UA-E-06: The 2023 Counteroffensive and the Attrition Phase (2023–2024)

Status: DRAFTWords: 9,734

1. Key Takeaways

  • The 2023–2024 period marks the transition of the Russo-Ukrainian war from the manoeuvre phase of 2022 (UA-E-05) into a war of attrition that no offensive operation by either side has since decisively broken. Where the September–November 2022 record was characterised by rapid Ukrainian operational manoeuvre against a structurally-weakened Russian grouping, the 2023–2024 record is characterised by dense prepared defences, layered minefields, contested airspace saturated by reconnaissance and strike drones, and grinding positional battles measured in metres and tree-lines rather than the tens of kilometres of the Kharkiv collapse. The contrast between the two phases is the central analytical fact of this document: the operational lessons of 2022 did not transfer to 2023, and the structural reasons why they did not are the subject of the principal three-account contestation treated below.

  • The winter 2022–2023 Bakhmut battle — the longest and among the bloodiest single engagements of the war — consumed both armies' offensive momentum before the 2023 counteroffensive began. The battle for Bakhmut (a Donetsk-Oblast town of pre-war population approximately 70,000) ran from roughly August 2022 through its fall on 20 May 2023, with the Wagner Group private military company under Yevgeny Prigozhin as the principal Russian assault force. The town's military value was widely contested even within Ukrainian and Western analytical commentary; its symbolic value, and the attritional calculus of trading Russian (especially Wagner-recruited convict) lives for Ukrainian time and Russian materiel, dominated the Ukrainian decision to hold it. Casualty figures for Bakhmut remain among the most contested of the war [TBD-VERIFY: estimates of combined killed-and-wounded across the Bakhmut battle range from the tens of thousands to well over 100,000; no figure should be treated as established].

  • The long-delayed summer-2023 counteroffensive, launched in earnest on or around 4 June 2023 against the prepared Russian "Surovikin Line" in Zaporizhzhia Oblast, failed to achieve its operational objective of severing the Russian "land bridge" to Crimea. Across roughly June–November 2023 Ukrainian forces — including a dozen Western-trained-and-equipped brigades fielding Leopard 2 and Leopard 1 tanks, M2 Bradley and other infantry fighting vehicles — assaulted along three principal axes: the Robotyne–Tokmak axis in western Zaporizhzhia (the main effort), the Velyka Novosilka axis on the Zaporizhzhia–Donetsk boundary, and the Bakhmut-flank axis. The deepest advance, the September 2023 capture of Robotyne and the penetration toward Verbove, fell far short of Tokmak (let alone Melitopol or the Sea of Azov coast). Territorial gains for the entire counteroffensive are measured in low hundreds of square kilometres [TBD-VERIFY: total 2023-counteroffensive territorial gain is variously reported as a few hundred square kilometres; precise figures are contested and not established here].

  • Why the 2023 counteroffensive stalled is the document's principal three-account contestation, and the three accounts are not mutually exclusive. The Ukrainian/Zaluzhnyi account emphasises insufficient and late Western weapons — too few brigades, delivered too slowly, with no air superiority and (critically) no Western combat aircraft until the F-16 timeline slipped into 2024 — so that Ukraine was asked to breach a prepared defence by the rules of combined-arms manoeuvre without the means combined-arms manoeuvre requires. The Western-assessment account (reflected in the Washington Post post-mortem and parts of US/RUSI commentary) emphasises flawed Ukrainian operational choices: the dispersal of effort across three axes rather than concentration of mass, the abandonment of Western-advised combined-arms breaching tactics in favour of dismounted infantry attrition after early armoured losses, and command-coordination friction. The structural account — articulated by Zaluzhnyi himself in his 1 November 2023 Economist essay — holds that the war has entered a "positional" stage in which the maturation of reconnaissance-strike drone complexes, dense mining, and electronic warfare has made operational breakthrough structurally very difficult for either side regardless of national choices.

  • Valery Zaluzhnyi's 1 November 2023 Economist essay declaring the war "positional" was a primary-source intervention of unusual candour from a sitting commander-in-chief and a precipitant of the Zaluzhnyi–Zelensky rupture. In the accompanying nine-page document "Modern Positional Warfare and How to Win in It," Zaluzhnyi argued the front had reached a stalemate analogous to the First World War's trench deadlock, identified five capability gaps (air power, electronic warfare, counter-battery, mine-breaching, and reserve mobilisation) Ukraine needed to close to restore manoeuvre, and warned against a prolonged positional war that favoured Russia's larger resource base. President Zelensky publicly pushed back against the "stalemate" framing. The essay is widely read as a contributing factor to Zaluzhnyi's February 2024 replacement as commander-in-chief by General Oleksandr Syrskyi and reassignment as ambassador to the United Kingdom.

  • The parallel deep-strike and Black Sea campaign was the clearest Ukrainian success of 2023–2024 and the principal counterweight to the ground-offensive disappointment. Even as the land counteroffensive stalled, Ukraine — using domestically-produced long-range drones, the Magura-V5 and Sea Baby naval drones, and Western-supplied Storm Shadow / SCALP-EG cruise missiles (UK from May 2023, France from July 2023) and US ATACMS (from October 2023) — inflicted sustained attrition on the Russian Black Sea Fleet, struck the Sevastopol fleet headquarters, sank or damaged a substantial fraction of the fleet's combatants, struck the Crimean (Kerch) Bridge (notably the 17 July 2023 attack following the October 2022 strike), and forced the Russian navy to disperse from Sevastopol toward Novorossiysk. The cumulative effect was the de facto breaking of the Russian Black Sea blockade and the reopening of a Ukrainian maritime grain-export corridor after the July 2023 Russian withdrawal from the Black Sea Grain Initiative.

  • The October 2023 – April 2024 United States aid hold-up is the document's second principal three-account contestation, bearing directly on the worst Ukrainian battlefield period of the war. A roughly six-month suspension of new US military aid — the result of the supplemental appropriation stalling in the US Congress from autumn 2023 until the $61 billion Ukraine component was signed on 24 April 2024 — coincided with acute Ukrainian shortages of artillery ammunition and air-defence interceptors. The decisive-factor account (Ukrainian officials, much front-line reporting) holds the aid gap directly caused the fall of Avdiivka and subsequent reverses; the one-of-several-factors account (parts of Western analysis) holds that the aid gap compounded but did not alone cause reverses also driven by Ukraine's manpower shortfall, fortification deficits, and the structural attrition balance.

  • The 17 February 2024 fall of Avdiivka was the most significant Russian territorial gain since the May 2023 capture of Bakhmut and the symbolic low point of the aid-gap period. Avdiivka, a fortified Donetsk-Oblast town contested since 2014 and a launch-point for Ukrainian fires against occupied Donetsk city, fell after months of costly Russian assault as Ukrainian units — newly under Syrskyi's command — withdrew under conditions of severe shell hunger, with reports of artillery firing ratios heavily favouring Russia at the battle's end [TBD-VERIFY: reported Ukrainian-to-Russian artillery firing ratios at Avdiivka, e.g. on the order of 1:5 to 1:10, are widely cited but not independently established].

  • The manpower-and-mobilisation crisis emerged through 2023–2024 as the structural Ukrainian constraint that no quantity of Western equipment could substitute for, and it is treated in depth at UA-D-04. The protracted parliamentary fight over a new mobilisation law (debated through late 2023 and into 2024, with a revised law adopted in April 2024 and effective from May 2024), the politically-fraught lowering of the mobilisation age from 27 to 25, and chronic disputes over rotation, demobilisation, and conscription enforcement reflected a binding demographic-and-political constraint distinct from, and in some assessments more important than, the materiel question.

  • The 6 August 2024 Kursk cross-border incursion was Ukraine's surprise operational counter-move and the first occupation of internationally-recognised Russian territory by a foreign army since the Second World War. Ukrainian mechanised forces crossed into Russia's Kursk Oblast, rapidly seizing a salient including the town of Sudzha and a reported area in the hundreds of square kilometres [TBD-VERIFY: the maximum Ukrainian-held area in Kursk Oblast, variously reported at its August–September 2024 peak as on the order of 1,000+ square kilometres, is contested and not established here]. The operation's strategic rationale — bargaining-chip territory, forcing Russian redeployment, restoring an offensive initiative, and a morale-and-information effect — is itself contested, and the incursion is anchored separately for the corpus at UA-E-07 (Kursk Incursion, when written); this document treats it as the closing operational event of the 2023–2024 attrition narrative.

  • The drone-warfare revolution — first-person-view (FPV) strike drones, reconnaissance-strike complexes, and naval drones — is the through-line technological transformation of the 2023–2024 period and a principal cause of the structural shift to attrition. The saturation of the front by cheap FPV drones (with annual production scaling into the millions by 2024, treated at UA-E-08), persistent ISR (intelligence, surveillance, reconnaissance) drone coverage that made massing armour for breakthrough nearly suicidal, and the emergence of a contested "drone kill zone" extending kilometres behind each front line transformed the tactical character of the war and underwrote Zaluzhnyi's "positional" thesis. The naval-drone campaign that broke the Black Sea blockade was the same revolution applied at sea.

  • By the end of 2024 the war's trajectory was itself contested — the document's third three-account question. The Ukrainian-resilience reading emphasises that Ukraine had survived the aid gap, broken the Black Sea blockade, scaled a domestic drone industry, and seized Russian territory at Kursk — that the line held and Russia's gains remained marginal at enormous cost. The slow-Russian-grind reading emphasises that Russia held the initiative across most of the line through 2024, took Avdiivka and a string of Donbas settlements, retained quantitative advantages in manpower and materiel, and was attriting Ukraine faster than Ukraine could regenerate. The mutual-exhaustion reading emphasises that neither side could achieve operational breakthrough, that both faced binding constraints (Ukraine on manpower, Russia on equipment quality and economic sustainability), and that the resulting deadlock set the conditions for the negotiation phase that opened in January 2025 (UA-D-05).

2. From Manoeuvre to Attrition: The Post-Kherson Operational Transition (November 2022 – Spring 2023)

The 2023–2024 phase of the war cannot be understood except against the operational baseline established in late 2022 and documented at UA-E-05. The Kharkiv counteroffensive of September 2022 and the Kherson liberation of November 2022 had produced an expectation — in Ukrainian public messaging, in Western political and media commentary, and to some degree within Western and Ukrainian military planning — that 2023 would extend the manoeuvre successes of 2022 into a decisive breaking of the Russian position in the south. The operational reality of 2023 confounded that expectation, and the structural reasons for the confounding were already taking shape over the winter of 2022–2023.

2.1 The Three Structural Changes Over the Winter of 2022–2023

Three structural changes distinguished the operational environment of 2023 from that of 2022. First, the 21 September 2022 Russian partial mobilisation (documented at UA-E-05) had injected an estimated 300,000 mobilised personnel into the Russian force structure; however poorly trained and equipped, these troops gave Russia the manpower to hold a continuous, densely-manned defensive line by spring 2023 — eliminating the thinly-held frontages that the Kharkiv collapse had exploited. Second, from October 2022 the Russian command, following the appointment of General Sergei Surovikin as overall theatre commander, had begun constructing extensive layered field fortifications across the occupied south and east — the defensive system that Ukrainian and Western commentary came to call the "Surovikin Line." Third, the reconnaissance-strike drone complex that would define 2023–2024 was maturing on both sides, progressively closing the surveillance gaps and creating the persistent battlefield transparency that makes massing forces for a breakthrough extraordinarily dangerous.

2.2 The Surovikin Line

The Surovikin Line was not a single trench but a defence in depth, typically comprising (from the Ukrainian side outward) a forward security zone seeded with dense minefields and covered by artillery and drones; a first main defensive belt of trenches, dragon's-teeth anti-tank obstacles, and anti-tank ditches; and one or more subsequent belts to absorb any penetration of the first. In the principal Zaporizhzhia sector the defensive system was widely reported as the most heavily fortified terrain in Europe since the Second World War, with minefield densities that RUSI's Watling and Reynolds and other front-line observers described as without precedent in recent conventional warfare [TBD-VERIFY: reported minefield densities — e.g. claims of up to five mines per square metre in places — are widely cited but not independently established here]. The depth and density of this system, more than any single subsequent decision, framed the operational problem the 2023 counteroffensive set out to solve.

2.3 The Winter Positional Battles

Through the winter of 2022–2023 the front largely froze into positional fighting, with two principal exceptions: the protracted Russian (largely Wagner-led) assault on Bakhmut in the east, and a costly, ultimately failed Russian offensive effort around Vuhledar in southern Donetsk Oblast in early 2023 that produced heavy Russian armoured losses and is frequently cited as an early demonstration of how transparent, drone-and-mine-saturated terrain punishes massed armour. The winter thus delivered a dual message that the summer would amplify: prepared defences supported by drones and artillery were extremely difficult to break, and the side that attacked across such terrain paid disproportionately. This was as true of the Russian failure at Vuhledar as it would prove of the Ukrainian difficulties at Robotyne.

3. The Bakhmut Meat-Grinder and the Wagner Group (Summer 2022 – May 2023)

The battle for Bakhmut was the longest single engagement of the war and the principal attritional event of the period bridging the 2022 counteroffensives and the 2023 offensive. It also brought the Wagner Group private military company, and its proprietor Yevgeny Prigozhin, to the centre of the Russian war effort — with consequences that extended to the abortive June 2023 Wagner mutiny inside Russia.

3.1 The Course of the Battle

Russian assaults on Bakhmut — a Donetsk Oblast town of some 70,000 pre-war residents, known before 2016 as Artemivsk — intensified from around August 2022 through the town's effective fall on 20 May 2023, when Prigozhin announced Wagner had taken the last urban districts. The Russian method was attritional in the most literal sense: repeated small-unit assaults, often using convicts recruited by Wagner under its "Project K" prisoner-recruitment scheme to identify and absorb Ukrainian fire, followed by exploitation by more capable units and overwhelming artillery — a slow envelopment that left Ukrainian forces holding a progressively narrowing pocket and a single contested supply road toward Chasiv Yar. By early 2023 Bakhmut had become the eastern front's focal point and the principal locus of Russian offensive effort, drawing in Ukrainian reserves whose diversion from the summer offensive is the question Section 3.2 takes up.

3.2 The Contested Military Logic

Whether holding Bakhmut was militarily sound was contested in real time, including within Ukrainian and allied circles. The case for holding — articulated by President Zelensky and the General Staff — rested on the attritional exchange (Bakhmut was understood as a place to destroy Russian and especially Wagner manpower at a favourable ratio while Western-equipped brigades were generated for the summer offensive), on the operational value of denying Russia a springboard toward Kramatorsk and Sloviansk, and on the symbolic-political cost of a visible withdrawal. The case against — voiced by some Western officials and analysts and reportedly by some Ukrainian commanders — held that the town's intrinsic military value was low, that the defence was consuming Ukrainian units and ammunition that the summer counteroffensive would need, and that the favourable-exchange premise was not clearly borne out as Ukrainian losses mounted. The post-mortem debate over whether Bakhmut's defence degraded the subsequent counteroffensive remains unresolved.

3.3 Casualties

Bakhmut casualty figures are among the least reliable of the war and should be treated with extreme caution. Ukrainian, Russian, Wagner, and Western sources have offered widely divergent figures, frequently for propaganda purposes [TBD-VERIFY: combined killed-and-wounded estimates for the Bakhmut battle span from the tens of thousands to figures above 100,000; Wagner's own reported losses, including convict recruits, are separately contested; no figure is established here]. What is not in serious dispute is that the battle was extraordinarily costly to both sides and that it consumed offensive combat power on both sides before the summer of 2023.

3.4 Wagner, Prigozhin, and the June 2023 Mutiny

Bakhmut elevated Prigozhin's public profile and sharpened his conflict with the Russian Ministry of Defence under Sergei Shoigu and Chief of the General Staff Valery Gerasimov, whom Prigozhin publicly accused of starving Wagner of ammunition. This feud culminated in the short-lived armed mutiny of 23–24 June 2023, when Wagner forces seized Rostov-on-Don and advanced toward Moscow before Prigozhin abruptly halted under a Belarus-brokered arrangement; Prigozhin died in an unexplained plane crash on 23 August 2023. The mutiny falls primarily within the Russian-governance corpus (RU-block, when written), but its Ukrainian-war relevance is direct: it briefly raised Ukrainian and Western hopes of Russian internal fragmentation precisely as the Ukrainian summer counteroffensive was opening, hopes that the offensive's subsequent stall did not vindicate.

4. The Long-Delayed Summer Counteroffensive: Force Generation and the Equipment Question (Winter 2022–2023 – June 2023)

4.1 The Western-Trained Brigades

Through the winter and spring of 2022–2023 Ukraine and its partners generated a tranche of new brigades trained and equipped to a partially Western standard for the express purpose of the summer offensive. Training was conducted across multiple programmes, including the UK-led Operation Interflex and dedicated brigade-level training in Germany and elsewhere. The equipment package was a heterogeneous mix: German-supplied Leopard 2 main battle tanks and older Leopard 1s, US-supplied M2 Bradley infantry fighting vehicles, a range of other Western and Soviet-legacy armour, and Western artillery. Several of these brigades were committed to the main southern axis.

4.2 The Equipment Debate in Advance

The composition and sufficiency of this package became, in retrospect, the heart of the first three-account contestation. The Ukrainian position — pressed publicly throughout the first half of 2023 — was that the package was too small and arriving too late: too few tanks and armoured vehicles, persistent shortfalls in mine-breaching equipment, no long-range fires sufficient to suppress Russian defences in depth before October 2023, and above all no Western combat aircraft and therefore no prospect of even local air superiority. Western governments, conscious of their own stock limits and of escalation-management concerns, supplied what RUSI and others later characterised as enough to attempt an offensive but not enough to guarantee one against the Surovikin Line.

4.3 The Delay

The offensive was widely anticipated for the spring but did not begin in earnest until on or around 4 June 2023. Ukrainian officials attributed the delay to incomplete deliveries, the need to complete brigade training and integration, weather and ground conditions, and ammunition husbanding. The delay itself became a contested factor: critics argued it gave Russia additional weeks to deepen the Surovikin Line, while Ukrainian planners argued an earlier start with unready forces would have been worse. The delay also raised Western and domestic expectations to a level the operation could not meet — a gap between expectation and outcome that shaped the post-mortem as much as the battlefield results did.

5. The Assault on the Surovikin Line: Robotyne, Velyka Novosilka, and the Bakhmut Flank (June–November 2023)

5.1 The Operational Design and Its Three Axes

The counteroffensive's principal objective was to drive south from western Zaporizhzhia toward Tokmak, Melitopol, and the Sea of Azov coast, severing the Russian "land bridge" connecting Russia to Crimea through occupied southern Ukraine. The effort was distributed across three axes — the Robotyne–Tokmak axis (the main effort), the Velyka Novosilka axis on the Zaporizhzhia–Donetsk boundary, and a Bakhmut-flank axis — rather than concentrated as overwhelming mass on one, a dispersal central to the Western critique in Section 7.

5.2 The Opening and the Early Armoured Losses

Early June 2023 produced one of the offensive's most-discussed episodes: Ukrainian mechanised columns attempting Western-advised combined-arms breaching ran into dense minefields under artillery, attack-helicopter, and drone fire, suffering visible losses of Western-supplied equipment (including Leopard 2 tanks and Bradley fighting vehicles) south of Mala Tokmachka. The episode crystallised the central tactical problem: breaching doctrine assumes the attacker can suppress the defender's artillery and aviation and clear lanes under cover, but without air superiority, sufficient counter-battery fire, or adequate mine-clearing assets, and against a defender with persistent drone overwatch, the columns were detected, channelled into minefields, and struck before they could exploit — Russian information operations seized on the resulting imagery despite most damaged Bradleys later being recovered and repaired. The losses prompted the shift to dismounted infantry breaching treated in Section 6.

5.3 Robotyne and the Limit of Advance

Ukrainian forces then shifted to a slower, dismounted-infantry approach — small groups clearing mines and assaulting tree-lines and trenches on foot, trading tempo for reduced armour exposure. This produced the offensive's principal territorial achievement, the capture of Robotyne (reported late August 2023) and a penetration toward Verbove that breached the leading edge of the first Russian defensive belt — but the slower tempo gave Russian command time to identify the main effort and commit reserves, including redeployed airborne formations, containing the penetration before it could reach the more lightly defended ground planners had hoped lay behind. The advance stalled well short of Tokmak, itself only an intermediate objective; by autumn 2023, with weather closing in, ammunition constrained, and Russian reserves committed in depth, the southern advance had culminated without operational penetration.

5.4 The Velyka Novosilka and Bakhmut-Flank Results

The Velyka Novosilka axis produced early gains of several villages (including Staromaiorske and Urozhaine through summer 2023) but likewise culminated short of operational significance. On the Bakhmut flank, Ukrainian forces achieved limited local advances around Klishchiivka and Andriivka without reversing the May 2023 loss of the town. None of the three axes achieved the operational breakthrough the offensive was designed to produce.

5.5 The Aggregate Result

The aggregate territorial result of the entire summer–autumn 2023 counteroffensive was modest in the extreme relative to its objectives — measured in low hundreds of square kilometres of mostly agricultural ground and a handful of villages, against an objective of reaching the Azov coast roughly 100 kilometres to the south [TBD-VERIFY: the total territorial gain of the 2023 counteroffensive, variously reported in the few-hundred-square-kilometres range, and the depth of the deepest penetration, are contested and not established here]. The "land bridge" remained intact; Melitopol and the Azov coast were never seriously threatened; and Tokmak, the first major operational objective on the main axis, was never reached. The deepest Ukrainian penetration in the south breached the first Russian main defensive belt only in a narrow sector around Robotyne–Verbove, where it was contained by committed Russian reserves and by the depth of the fortification system behind the first belt. The gap between this result and the pre-offensive expectation — an expectation that Ukrainian messaging, Western commentary, and some Western planning had all helped inflate — set the terms of the post-mortem and of Zaluzhnyi's November intervention. RUSI's Stormbreak report (Watling and Reynolds, 4 September 2023), written from front-line observation as the offensive culminated, framed the core problem as the difficulty of conducting a breaching operation through a prepared, drone-surveilled, deeply-mined defence without air superiority and with insufficient enabling assets — a framing that anticipated both the materiel and the structural accounts of the failure.

6. Why It Stalled: The Three-Account Contestation

The explanation of the 2023 counteroffensive's failure to achieve operational breakthrough is the document's first and most-developed three-account contestation. The three accounts overlap and are best read as emphasising different links in a single causal chain rather than as mutually-exclusive alternatives.

6.1 The Ukrainian / Zaluzhnyi Account: Insufficient and Late Western Weapons

The Ukrainian command's account — articulated by Zaluzhnyi, by Ground Forces and brigade commanders in interviews, and by Ukrainian officials — emphasises the materiel and capability deficit. On this account, Ukraine was asked to breach the most heavily fortified defensive system in modern European warfare without the elements that combined-arms breaching doctrine requires: without air superiority or even local air parity, because no Western combat aircraft had arrived (the F-16 timeline, Section 7, had slipped to 2024); with too few mine-breaching vehicles and engineering assets to clear lanes under fire; with long-range fires (ATACMS) arriving only in October 2023, too late to shape the summer battle; and with too few trained brigades to generate decisive mass. The deliveries that did arrive were, on this account, "too little, too late" — sufficient to attempt the offensive, insufficient to succeed.

6.2 The Western-Assessment Account: Flawed Operational Choices

A second account — prominent in the Washington Post's December 2023 post-mortem reconstruction and in parts of US and allied commentary — emphasises Ukrainian operational choices. On this account, Ukraine dispersed effort across three axes instead of concentrating overwhelming mass on the main southern axis as Western planners had urged in pre-offensive war-gaming; abandoned the Western-advised combined-arms breaching method after the early-June armoured losses in favour of a slower attritional dismounted approach that surrendered tempo and allowed Russian reserves to redeploy; and suffered from command-coordination friction and from a force only partially trained to the combined-arms standard the plan assumed. This account does not deny the materiel constraints but holds that within those constraints the operation could have been conducted more effectively.

6.3 The Structural Account: Drones and Mines Have Dominated the Offence

The third account — articulated most influentially by Zaluzhnyi himself in his 1 November 2023 Economist essay (Section 8) and developed in RUSI and other tactical analysis — holds that the war has entered a structurally defensive, "positional" phase. The maturation of reconnaissance-strike drone complexes has made the battlefield transparent for tens of kilometres, so that any concentration of forces for a breakthrough is detected and struck before it can mass; dense minefields, electronic warfare, and ubiquitous artillery compound the effect. On this reading, the failure of the 2023 offensive was less a failure of Western supply or Ukrainian command than a structural condition of contemporary high-intensity warfare that would have defeated a better-supplied, better-coordinated offensive too — until one side closes the specific capability gaps (air power, electronic warfare, counter-battery, mine-breaching, reserves) that Zaluzhnyi enumerated.

6.4 The Role of Expectation

A distinct strand running through all three accounts is the role of inflated expectation. The 2023 offensive was preceded by a public build-up — Ukrainian messaging, Western political signalling, and intensive media coverage of the Western-equipped brigades — that set the standard of success implicitly at a decisive breakthrough comparable to Kharkiv 2022. Measured against that standard, the offensive was a failure; measured against the realistic problem (breaching the most-fortified terrain in modern Europe without air superiority), the modest gains were closer to the achievable ceiling. Freedman, Kofman, and Gady each noted in 2023–2024 commentary that the expectation-setting itself contributed to the political damage of the outcome, feeding Western "war fatigue" narratives that the result, soberly assessed, did not strictly warrant. The pre-offensive loss of strategic surprise — the operation's general direction and timing were widely anticipated, including by Russia, which used the time to deepen the Surovikin Line — is a related cost that all three accounts acknowledge.

6.5 Synthesis

The three accounts are complementary. The structural account explains why breakthrough was hard for anyone; the materiel account explains why Ukraine specifically lacked the means (air power, fires, engineering, mass) that might have overcome the structural difficulty; and the operational account explains why the means Ukraine did have may not have been employed to best effect. The post-2023 analytical consensus (RUSI, Gady, Kofman, Freedman) does not adjudicate a single cause but treats the outcome as overdetermined — the product of a structurally defence-dominant battlefield, an under-resourced attacking force, and contestable operational choices, no one of which is sufficient alone to explain the result.

7. The Equipment Pipeline and the F-16 Timeline

The materiel account of Section 6 turns on the specifics of the Western equipment pipeline across 2023, which is worth setting out because the timing — what arrived, and when — bears directly on the counteroffensive's outcome and on the subsequent aid-gap battle.

7.1 Armour and Artillery

The tank debate of the winter of 2022–2023 — resolved in January 2023 with the German decision to authorise Leopard 2 transfers and re-exports and the parallel US commitment of M1 Abrams (which arrived only in autumn 2023, too late for the offensive) — delivered Leopard 2s, Leopard 1s, Bradleys, and other armour in numbers sufficient to equip several brigades but not to provide the depth of replacements that high-intensity mechanised assault against prepared defences consumes. Western artillery (M777, PzH 2000, Caesar, and others) and ammunition were chronically constrained by Western production limits — the artillery-ammunition shortfall that would become acute during the 2024 aid gap was already a binding factor in 2023.

7.2 Long-Range Fires: Storm Shadow, SCALP-EG, and ATACMS

The long-range strike picture improved across 2023 but on a timeline that lagged the ground offensive. The United Kingdom supplied Storm Shadow air-launched cruise missiles from approximately May 2023, and France followed with the equivalent SCALP-EG from approximately July 2023; these gave Ukraine a deep-strike capability against Russian rear-area headquarters, logistics, and (critically) Black Sea Fleet and Crimea targets. The United States, after prolonged internal debate driven by stock and escalation concerns, supplied the longer-range ATACMS only from October 2023 — after the summer offensive had culminated. The lateness of ATACMS is a recurring item in the Ukrainian "too little, too late" account.

7.3 The F-16 Timeline

No item better encapsulates the air-power gap than the F-16. A multinational coalition to provide F-16 fighters and to train Ukrainian pilots was formed in 2023, with a Danish-and-Dutch-led commitment announced in August 2023; but pilot and maintainer training timelines, basing arrangements, and delivery sequencing meant the first F-16s reached Ukraine only in approximately August 2024 — more than a year after the counteroffensive opened and after it had failed. For the entire 2023 offensive, therefore, Ukraine prosecuted an assault on a prepared defence with no Western combat aircraft and against a Russian air force that, while constrained by Ukrainian ground-based air defence, could employ standoff glide bombs (the increasingly-used UMPK-kitted bombs that became a defining Russian weapon of 2024) and attack helicopters against the advancing brigades from beyond the reach of Ukrainian short-range defences. Even after their 2024 arrival, the F-16s were committed cautiously — primarily to air defence against missiles and drones and to standoff strike rather than to contested close air support over the front — reflecting both their limited numbers and the lethality of Russian long-range surface-to-air systems. The F-16 timeline is the single clearest illustration of the gap between what combined-arms breaching doctrine assumes and what Ukraine actually possessed in the summer of 2023, and it is the capability gap Zaluzhnyi placed first among the five in his November essay.

8. Zaluzhnyi's November 2023 "Positional War" Essay and the Command Rupture

8.1 The Essay

On 1 November 2023 The Economist published an interview with, and a signed nine-page essay by, the Commander-in-Chief of the Armed Forces of Ukraine, General Valery Zaluzhnyi, under the framing that the war had reached a "stalemate." In the accompanying document, "Modern Positional Warfare and How to Win in It," Zaluzhnyi argued that the front had settled into a positional deadlock analogous to the trench stalemate of the First World War; that the technological conditions of the contemporary battlefield — persistent ISR drones, mines, electronic warfare, precision fires — favoured the defence and denied either side the conditions for operational manoeuvre; and that to break out of the deadlock Ukraine needed to achieve advantage in five areas: air power, electronic warfare, counter-battery capability, mine-breaching, and the building of reserves. He warned explicitly that a prolonged positional war advantaged Russia, with its larger population and resource base.

8.2 The Significance

The essay was a primary-source intervention of unusual candour from a sitting wartime commander-in-chief. Coming weeks after the counteroffensive's culmination, it functioned as a public acknowledgement that the offensive had not achieved its objectives and a public argument for the structural account of why. It reframed the strategic conversation away from imminent breakthrough and toward the long-war, capability-building, attritional logic that would dominate 2024. It is the foundational text of the "positional war" reading of the conflict and is cited throughout subsequent analytical literature.

8.3 The Zaluzhnyi–Zelensky Rupture

The essay also crystallised a growing tension between the General Staff and the Presidential Office. President Zelensky publicly disputed the "stalemate" characterisation, which he regarded as strategically and diplomatically damaging — feeding Western "war fatigue" and Russian narratives of inevitability at a moment when Ukraine needed to sustain Western political and materiel commitment. The disagreement was substantive (over the honest characterisation of the front) and political (over messaging, over mobilisation, and over the relationship between the military command and the political leadership). It culminated in February 2024 with Zelensky's replacement of Zaluzhnyi as commander-in-chief by General Oleksandr Syrskyi — the commander of the September 2022 Kharkiv counteroffensive (UA-E-05) — and Zaluzhnyi's subsequent appointment as Ukraine's ambassador to the United Kingdom. The command change is treated more fully at UA-I-07 and in the H-CSC biographies (when written); here it marks the institutional consequence of the counteroffensive's failure and of the honest reckoning Zaluzhnyi's essay forced.

9. The Deep-Strike Campaign and the Breaking of the Black Sea Blockade (2023–2024)

While the land counteroffensive disappointed, the parallel deep-strike and maritime campaign was the clearest Ukrainian operational success of 2023–2024 and is treated from the capability-development side at UA-E-08.

9.1 The Black Sea Fleet Attrition

Across 2023–2024 Ukraine conducted a sustained campaign against the Russian Black Sea Fleet using domestically developed naval drones (the Magura-V5 and Sea Baby uncrewed surface vessels), missiles including Storm Shadow/SCALP-EG and Neptune, and special-operations raids — striking the fleet's Sevastopol headquarters and ship-repair facilities and sinking or disabling a series of major combatants and support vessels [TBD-VERIFY: the count of Russian Black Sea Fleet vessels sunk or damaged across 2023–2024 — variously reported as roughly a third of the fleet's combatants over the war — and the named-vessel attributions and dates, are contested in detail and not established here], ultimately forcing the Russian navy to relocate much of its surviving fleet from Sevastopol eastward to Novorossiysk. The campaign's notable feature is that it was prosecuted by a country with effectively no conventional navy: Ukraine attrited a major surface fleet using cheap uncrewed vessels and standoff missiles, an asymmetric outcome that drew sustained analytical attention (CEPA, DFRLab, naval commentators) and that, by 2024, had substantially degraded the fleet's ability to project power in the western Black Sea.

9.2 The Crimean (Kerch) Bridge Strikes

The Crimean Bridge across the Kerch Strait — the principal physical and symbolic link between Russia and occupied Crimea, opened in 2018 — was struck on 8 October 2022 (treated at UA-E-05) and again on 17 July 2023, the latter attributed to a Ukrainian naval-drone operation that damaged the roadway and forced traffic restrictions. The strikes degraded the bridge's logistical role and forced Russia to rely more heavily on the vulnerable overland route through occupied southern Ukraine — the "land bridge" the land counteroffensive had failed to sever — for sustaining its Crimea and southern-front positions.

9.3 Breaking the Blockade and the Grain Corridor

The maritime campaign's strategic payoff was the de facto breaking of the Russian Black Sea blockade. The Black Sea Grain Initiative — the July 2022 UN-and-Turkey-brokered arrangement (treated at UA-F-05, when written) that had permitted Ukrainian grain exports from Odesa-area ports under a Joint Coordination Centre in Istanbul — was terminated by Russia in July 2023. Rather than accept renewed blockade, Ukraine established a unilateral humanitarian corridor hugging the western Black Sea coast, protected by the attrition of the Black Sea Fleet and by coastal anti-ship fires. Through late 2023 and 2024 this corridor restored Ukrainian seaborne exports toward and beyond pre-initiative volumes, a substantial economic and strategic achievement accomplished without a negotiated agreement and against Russian objection. The breaking of the blockade is the principal counter-example to any unqualified narrative of 2023–2024 as a period of Ukrainian failure.

10. The Strategic Shift to Attrition: The US Aid Hold-Up and the Fall of Avdiivka (October 2023 – Spring 2024)

10.1 The Aid Hold-Up

From autumn 2023 the flow of new US military aid to Ukraine effectively halted as a national-security supplemental appropriation including roughly $61 billion for Ukraine stalled in the US Congress amid domestic-political contestation, principally in the House of Representatives, where the package became entangled with US border-security demands and intra-Republican division. The Biden administration's existing Presidential Drawdown Authority funds were exhausted by late 2023, and absent a new appropriation no further large-scale drawdowns could be announced. The hold-up persisted until the supplemental was finally passed and signed on 24 April 2024 — roughly six months during which the United States, by far Ukraine's largest single supplier of artillery ammunition and air-defence interceptors, sent little or no new materiel. The gap coincided with, and on most accounts caused or sharply worsened, acute Ukrainian shortages of 155mm artillery ammunition and of the interceptors (Patriot and others) needed to defend cities and the front from Russian ballistic and cruise missiles, glide bombs, and Shahed-type one-way attack drones. European partners and the EU's own ammunition initiatives could not fully compensate on the relevant timescale, and the European one-million-shells pledge for the year to March 2024 fell short of its target. The aid gap thus produced a measurable degradation of Ukrainian fires and air defence precisely as Russia pressed its post-counteroffensive initiative.

10.2 The Fall of Avdiivka

The clearest battlefield consequence attributed to the aid gap was the fall of Avdiivka on 17 February 2024. Avdiivka — a fortified Donetsk-Oblast industrial town immediately north of occupied Donetsk city, contested since 2014 and heavily entrenched — had withstood Russian pressure for years. From October 2023 Russia mounted a sustained, costly assault; by February 2024 Ukrainian defenders, newly under Syrskyi's overall command, withdrew under conditions of severe shell hunger, with widely-reported claims that Russian artillery massively out-fired Ukrainian guns in the battle's final phase [TBD-VERIFY: reported Ukrainian-to-Russian artillery firing ratios at Avdiivka, sometimes cited at 1:5 or worse, are not independently established; Russian assault losses at Avdiivka were also reported as very heavy but are not established here]. Avdiivka was the most significant Russian gain since Bakhmut and the symbolic nadir of the aid-gap period.

10.3 The Three-Account Contestation on the Aid Delay

The battlefield significance of the US aid delay is the document's second three-account contestation. The decisive-factor account — advanced by Ukrainian officials and reflected in much front-line reporting — holds that the six-month gap directly caused the fall of Avdiivka and the broader spring-2024 reverses: with adequate shells and interceptors, the line would have held. The one-of-several-factors account — advanced in parts of Western analysis (Kofman, Gady, RUSI) — holds that the aid gap was real and damaging but compounded constraints that pre-dated and outlasted it: Ukraine's binding manpower shortfall (Section 11), under-prepared second-line fortifications, the structural attrition balance, and the cumulative exhaustion of units after Bakhmut and the failed counteroffensive. On this account the aid gap accelerated and worsened reverses that the manpower and fortification problems would have produced in some form regardless. The contestation matters because it bears directly on the lesson drawn: whether Ukraine's 2024 difficulties were primarily an artefact of a contingent US political failure (reversible) or of deeper structural constraints (not reversible by Western supply alone).

10.4 The Post-Avdiivka Grind

After Avdiivka, Russian forces pressed westward across the spring and summer of 2024 — taking a string of Donbas settlements (Ocheretyne, and later in 2024 pressure toward Pokrovsk and Toretsk) — at a slow pace and, on most accounts, at heavy cost, while Ukraine stabilised the line behind belatedly-constructed fortifications as the post-April-2024 US aid resumed. The pattern of 2024 was Russian initiative across most of the line, marginal Russian gains, and a Ukrainian defence that bent without breaking — the slow-grind reading of the war's trajectory (Section 14).

11. The Manpower and Mobilisation Crisis (2023–2024)

The structural constraint that emerged through 2023–2024 as the one no quantity of Western equipment could substitute for was manpower. This dimension is anchored at UA-D-04 (mobilisation, conscription law, and manpower architecture) and is treated here only in its operational-consequence aspect.

11.1 The Binding Constraint

By 2024 the Ukrainian war effort confronted a manpower problem with three components: the cumulative attrition of the 2022–2024 fighting (including the heavy losses at Bakhmut and in the failed counteroffensive); the difficulty of rotating exhausted units out of the line, as too few fresh formations existed to relieve them; and the political and demographic difficulty of generating new soldiers from a population already heavily mobilised, partly displaced abroad, and acutely sensitive to the fairness and enforcement of conscription. The asymmetry with Russia compounded the problem: Russia, drawing on a far larger population and sustaining recruitment through high financial inducements and the September 2022 mobilised cohort, could regenerate manpower at a pace Ukraine could not match without measures politically costly to a democratic government under martial law. Where 2022 had been a war of materiel improvisation and 2023 a war of equipment debates, 2024 increasingly became a war of manpower arithmetic — and the arithmetic, on the slow-grind reading (Section 14.2), did not favour Ukraine.

11.2 The Mobilisation-Law Fight

A protracted political struggle over a new mobilisation law ran through late 2023 and into 2024, reflecting the binding nature of the constraint and its political toxicity. A revised mobilisation law was adopted in April 2024 and took effect from May 2024, tightening registration, enforcement, and record-keeping; separately, the mobilisation age was lowered from 27 to 25 in April 2024 to widen the conscription pool. Disputes over demobilisation terms (soldiers who had served continuously since 2022 with no defined end of service), over draft-evasion enforcement, and over the equity of the burden persisted and were not resolved by the legislation. The manpower crisis is, in the assessment of several analysts (Kofman, Gady), at least as important as the materiel question in explaining Ukraine's 2024 difficulties — and unlike the materiel question it could not be solved by Western decisions.

12. The Drone-Warfare Revolution (2023–2024)

The technological through-line of the 2023–2024 period — and, on the structural account, the principal cause of the shift to attrition — was the maturation of drone warfare. The industrial side is treated at UA-E-08; this section treats the operational-tactical transformation.

12.1 The FPV Revolution and the Kill Zone

The defining tactical development of 2023–2024 was the proliferation of cheap first-person-view (FPV) strike drones — small, rapidly-produced, remotely-piloted quadcopters carrying explosive payloads, capable of striking individual vehicles, fortifications, and personnel at ranges of several to tens of kilometres at a tiny fraction of the cost of a guided artillery shell or missile. Combined with persistent reconnaissance drones providing near-continuous overwatch, FPVs created a contested "kill zone" extending several to many kilometres behind each front line, within which any movement — and especially any concentration of vehicles for an assault — risked rapid detection and strike. Ukrainian FPV-and-drone production scaled into the millions of units annually by 2024 (the "one-million-drones" and successor programmes, UA-E-08), and Russia matched the scaling. The mutual saturation of the front by drones is the proximate tactical reason that massed armoured breakthrough — the method the 2023 counteroffensive attempted in its opening days — had become extraordinarily costly.

12.2 The Structural Consequence

The drone revolution underwrites Zaluzhnyi's "positional" thesis directly. Persistent transparency and cheap precision strike together make the defence dominant: the attacker who masses is seen and struck before contact, while the defender, dispersed and entrenched, presents fewer lucrative targets. This is the technological mechanism behind the structural account of the counteroffensive's failure (Section 6.3) — and it cut both ways, defeating Russian massed-armour assaults (as at Vuhledar in early 2023 and across 2024) as reliably as it defeated Ukrainian ones.

12.3 The Naval-Drone Application

The same revolution applied at sea produced the Black Sea successes of Section 9: uncrewed surface vessels, cheap relative to the warships they attacked, sank or disabled major Russian combatants and helped break the blockade. The naval-drone campaign is the clearest demonstration that the drone revolution, defensively dominant on land, could be decisively offensive against an adversary — the Black Sea Fleet — that lacked an answer to it.

13. The Kursk Incursion as Surprise Counter-Move (August 2024)

13.1 The Operation

On 6 August 2024 Ukrainian mechanised forces launched a surprise cross-border incursion into Russia's Kursk Oblast, rapidly overrunning lightly-held border positions and seizing a salient that included the town of Sudzha and a substantial area of Russian territory [TBD-VERIFY: the maximum extent of Ukrainian-held territory in Kursk Oblast at the late-August/September 2024 peak, variously reported on the order of 1,000 square kilometres or more, and the number of settlements taken, are contested and not established here]. It was the first occupation of internationally-recognised Russian territory by a foreign army's regular forces since the Second World War, and it achieved strategic and tactical surprise after a period dominated by Russian initiative.

13.2 The Contested Rationale

The strategic rationale for Kursk is itself contested, and the incursion is anchored separately at UA-E-07 (Kursk Incursion, when written). The principal rationales offered — by Ukrainian officials and by analysts — included: seizing Russian territory as a bargaining chip for any future negotiation; forcing Russia to redeploy forces from the Donbas offensive (an effect that materialised only partially, as Russia continued pressing toward Pokrovsk through late 2024); restoring an offensive initiative and a morale-and-information victory after the grinding defensive year; and demonstrating to Western backers that Ukraine retained offensive capability. Critics questioned whether committing scarce, capable brigades to Kursk — rather than to the defence of the Donbas, where Russia continued to advance — was a sound allocation given the manpower constraint of Section 11. The incursion's ultimate strategic value remained unresolved at the close of 2024 and is properly assessed in the negotiation-phase context of UA-D-05.

13.3 Place in the Narrative

For this document, Kursk is the closing operational event of the 2023–2024 attrition narrative: a Ukrainian move that broke the pattern of the year, reasserted initiative, and created a territorial fact that would carry directly into the bargaining of the 2025 negotiation phase. It neither reversed the war's broader attritional trajectory nor altered the Donbas balance, but it ensured that Ukraine entered the negotiation phase holding Russian ground.

14. The Trajectory by End-2024: The Third Three-Account Contestation

The character of the war at the close of 2024 — and therefore the conditions under which the 2025 negotiation phase opened — is the document's third three-account contestation.

14.1 The Ukrainian-Resilience Reading

The first reading emphasises endurance and asymmetric success. On this account, Ukraine in 2024 survived the worst: it weathered a six-month US aid gap without strategic collapse, broke the Black Sea blockade and restored its seaborne exports, built a domestic drone industry producing at a scale that partially offset Western-supply uncertainty, took the war onto Russian soil at Kursk, and held a continuous front against a larger adversary. The line bent at Avdiivka and in the Donbas but did not break; Russian gains, measured against Russian losses, were marginal. This reading stresses Ukrainian agency and the contingent, reversible nature of the 2024 reverses.

14.2 The Slow-Russian-Grind Reading

The second reading emphasises the adverse trend. On this account, Russia held the strategic initiative across most of the front through 2024, took Avdiivka and a steady accumulation of Donbas settlements, retained quantitative advantages in manpower, artillery ammunition, and glide-bomb employment, and was attriting Ukraine — especially Ukrainian manpower — faster than Ukraine could regenerate it. On this reading the 2024 trajectory, if extrapolated, favoured Russia, and the Kursk incursion was a tactically-bold but strategically-questionable diversion from a defensive task Ukraine was slowly losing.

14.3 The Mutual-Exhaustion Reading

The third reading emphasises the deadlock. On this account neither side could achieve operational breakthrough — the structural, drone-and-mine-dominated, defence-favouring conditions of Section 12 denied manoeuvre to both — and both faced binding constraints: Ukraine on manpower, Russia on equipment quality, trained personnel, and the economic sustainability of a war economy under sanctions. The 2023 Ukrainian offensive and the 2024 Russian grind alike produced costly, marginal results. This reading holds that the war by end-2024 had reached the kind of mutual-exhaustion equilibrium in which negotiation becomes thinkable not because either side has won but because neither can — the condition that the January 2025 Trump-2 negotiation track (UA-D-05) would test.

14.4 Synthesis

As with the counteroffensive-failure and aid-delay contestations, the three trajectory-readings are not mutually exclusive: Ukraine was simultaneously resilient (it held and innovated), losing ground slowly (Russia advanced), and locked with Russia in a deadlock neither could break. The disagreement among analysts is one of emphasis and extrapolation rather than of fact — all three readings accept the same operational record (a held but slowly-receding land front, a won Black Sea, a held Russian salient, a strained manpower base) and differ over which trend to project forward. Which emphasis one adopts shaped — and continues to shape — the assessment of whether the negotiation phase that opened in 2025 represented a reasonable settlement of an unwinnable war, a premature concession of a war Ukraine could still have turned, or the inevitable terminus of mutual exhaustion. This document does not adjudicate among them; it establishes the operational record on which the adjudication rests.

15. Conclusion and Forward View

The 2023–2024 period transformed the Russo-Ukrainian war from the manoeuvre conflict of 2022 (UA-E-05) into the positional, attritional war that Valery Zaluzhnyi named in November 2023 and that has defined it since. The arc of the period is one of confounded expectation and adaptive endurance. The Bakhmut battle consumed both armies' momentum before the decisive year had begun. The long-prepared summer counteroffensive, on which Ukrainian and Western hopes had been concentrated, broke against the minefields and drones of the Surovikin Line and achieved a fraction of its objectives — for reasons that the document's first three-account contestation locates in a combination of late and insufficient Western weapons (the Ukrainian account), contestable Ukrainian operational choices (the Western account), and a structurally defence-dominant battlefield (the structural account, Zaluzhnyi's own). The US aid hold-up of October 2023 – April 2024 produced the war's worst Ukrainian battlefield period and the fall of Avdiivka, though whether it was the decisive cause or one of several compounding factors is itself contested. The manpower crisis emerged as the binding constraint no equipment could substitute for. And against this ground-war disappointment, Ukraine recorded its clearest successes off the battlefield's main axis: the deep-strike campaign that broke the Black Sea blockade and reopened the grain corridor, and the drone revolution that scaled a domestic industry and reshaped the tactical character of the war. The Kursk incursion of August 2024 closed the period by reasserting Ukrainian initiative and seizing Russian territory that would carry into the bargaining to come.

The forward view is set by the third three-account contestation. Whether the war by end-2024 is best read as Ukrainian resilience, slow Russian grind, or mutual exhaustion conditions the assessment of everything that follows. What is not contested is that the manoeuvre optimism of 2022 was gone, that neither side could break the other by offensive action, and that the resulting deadlock — a front largely static, a Black Sea reopened, a Russian salient occupied, a Ukrainian manpower base strained — set the conditions under which the 2025–2026 ceasefire negotiations and peace architecture (UA-D-05) would open in January 2025. This document ends at that threshold. The defence-industrial and drone dimensions that underwrote both the deep-strike successes and the attritional stalemate are developed at UA-E-08; the manpower-and-mobilisation crisis at UA-D-04; the Kursk incursion at UA-E-07 (when written); and the command rupture that removed Zaluzhnyi at UA-I-07 and the relevant H-CSC biographies (when written). The operational record established here is the baseline against which the negotiation phase, and any eventual settlement, must be read.
