On March 5, 2022, the wreck of the sailing ship Endurance was found in the depths of the Weddell Sea off the coast of Antarctica. This, of course, was the vessel lost in Ernest Shackelton’s third expedition to Antarctica, which became trapped in the ice and sank in 1915. The story of that expedition is an extraordinary tale of human fortitude – with the Endurance lost to the ice, Shackleton’s crew evacuated to a loose ice flow where they camped for nearly 500 days, drifting about the Antarctic seas, before making a desperate dash across the open ocean in an open 20 foot lifeboat, finally reaching the southern shore of inhospitable and mountainous South Georgia Island, which they then had to cross on foot to reach the safety of a whaling station.

The story itself has an essentially mythic quality to it, with Shackleton’s crew surviving for years on free floating ice floes in the most inhospitable seas on earth. For our purposes, however, it is the story’s coda that is particularly interesting. In Shackleton’s memoirs, he remembered that, upon finally reaching the safety of the Stromness whaling station, one of his first questions was about the war in Europe. When Shackleton first set out on his ill-fated expedition on August 8, 1914, the First World War was less than a week old, and the German Army had just begun its invasion of Belgium. There was little expectation then that the war would proceed as it did, unleashing four years of slaughterous positional warfare that engulfed the continent.

Shackleton, having been adrift at sea for years, clearly did not imagine that the war could still be raging, and asked the commandant of the whaling station “tell me, when was the war over?”

The answer came back: “The war is not over. Millions are being killed. Europe is mad. The world is mad.”

The timing is serendipitous, since the discovery of the Endurance’s wreck, after more than a hundred years, happened to occur only a few weeks after the world again went mad, with the beginning of the Russo-Ukrainian War in February 2022. As time continues its inexorable march and the calendar turns yet again, the war is passing through its third full winter. In February, Z-World will be three years old.

Of course, modern communications make it extremely unlikely that anybody could be cut fully out of the loop for years at a time, like Shackleton and his men. Instead of being ignorant as to whether or not the war is over, many of us are exposed on a daily basis to footage of men being killed, buildings being blown up, and vehicles being shredded. Twitter has made it essentially impossible to live under a rock, or on an ice floe, as it were.

If anything, we have the very opposite problem of Shackleton – at least as far as our wartime information infrastructure goes. We are saturated in information, with daily updates tracking advances of a few dozen meters and never ending bombast about new game changing weapons (which seem to change very little), and bluster about “red lines”. This war seems to have an unyielding dynamic on the ground, and no matter how many grand pronouncements we hear that one side or the other is on the verge of collapse, the sprawling front continues to grind up bodies and congeal with bloody positional fighting.

It would seem difficult to believe that a high intensity ground war in Europe with hundreds of miles worth of front could be boring, yet the static and repetitive nature of the conflict is struggling to hold the attention of foreign observers who have little immediately at stake.

My intention here is a radical zoom-out from these demoralizing and fatiguing small scale updates (as valuable as the work of the war mappers is), and consider the aggregate of 2024 – arguing that this year was, in fact, very consequential. Taken as a whole, three very important things happened in 2024 which create a very dismal outlook for Ukraine and the AFU in the new year. More specifically, 2024 brought three important strategic developments:

1. Russian victory in southern Donetsk which destroyed the AFU’s position on one of the war’s key strategic axes.

2. The expenditure of carefully husbanded Ukrainian resources on a failed offensive towards Kursk, which accelerated the attrition of critical Ukrainian maneuver assets and substantially dampened their prospects in the Donbas.

3. The exhaustion of Ukraine’s ability to escalate vis a vis new strike systems from NATO – more broadly, the west has largely run out of options to upgrade Ukrainian capabilities, and the much vaunted delivery of longer range strike systems failed to alter the trajectory of the war on the ground.

Taken together, 2024 revealed a Ukrainian military that is increasingly stretched to the limits, to the point where the Russians were able to largely scratch off an entire sector of front. People continue to wonder where and when the Ukrainian front might begin to break down – I would argue that it *did* break down in the south over the last few months, and 2025 begins with strong Russian momentum that the AFU will be hard pressed to arrest.

Front Collapse in South Donetsk

What stands out immediately about the operational developments in 2024 is the marked shift of energies away from the axes of combat that had seen the most intense fighting in the first two years of the war. In a sense, this war has seen each of its fronts activate in a sequence, one after the other.

After the opening Russian offensive, which boasted as its signature success the capture of the Azov coastline and the linkup of Donetsk and Crimea, the action shifted to the northern front (the Lugansk-Kharkov axis), with Russia fighting a summer offensive which captured Severodonetsk and Lysychansk. This was followed by a pair of Ukrainian counteroffensives in the fall, with a thrust out of Kharkov which pushed the front back over the Oskil, and an operation directed at Kherson which failed to breach Russian defenses but ultimately resulted in a Russian withdrawal in good order over the Dnieper due to concerns over logistical connectivity and an over-extended front. Energies then pivoted yet again to the Central Donbas axis, with the enormous battle around Bakhmut raging through the spring of 2023. This was followed by the failed Ukrainian offensive on Russia’s defenses in Zaporozhia, in the south.

Just to briefly recapitulate this, we can enumerate several operational phases in the first two years of the war, occuring in sequence and each with a center of gravity in different parts of the front:

-A Russian offensive across the land bridge, culminating in the capture of Mariupol. (Winter-Spring 2022, Southern Front)

-A Russian offensive in Lugansk, capturing Severodonetsk and Lysychansk. (Summer 2022, Donets-Oskil front)

-Ukrainian Counteroffensives towards the Oskil and Kherson (Autumn 2022, Oskil and Dnieper fronts)

-The Russian assault on Bakhmut (Winter-Spring 2023, Central Front)

-Ukrainian counteroffensive on the land bridge (Summer 2023)

Amid all of this, the front that saw the least movement was the southeastern corner of the front, around Donetsk. This was somewhat peculiar. Donetsk is the urban heart of the Donbas – a vast and populous industrial city at the center of a sprawling conurbation, once home to some 2 million people. Even if Russia succeeds in capturing the city of Zaporizhia, Donetsk will be by far the most populous of Ukraine’s former cities to come under Moscow’s control.

In 2014, with the outbreak of the proto-Donbas war, Donetsk was the locus of much of the fighting, with the airport on the city’s northern approach the scene of particularly intense combat. This made it rather strange, then, that at the start of 2024 the Ukrainian Army continued to occupy many of the same positions that they built a decade prior. As intense fighting ebbed and flowed along other sectors of front, Donetsk remained besieged by a web of powerfully held Ukrainian defenses, anchored by heavily fortified urban areas stretching from Toretsk to Ugledar. Early Russian attempts to crack this iron ring open, including an assault on Ugledar in the winter of 2023, met with failure.

The signature operational development of 2024, then, was the re-activation of the Donetsk front, after years of static combat. It is not an exaggeration to say that after years of coagulation, the Russian Army cracked this front wide open in 2024 and Ukraine’s long and strongly held network of urban strongpoints collapsed.

The year began with the AFU fighting for its fortress in Avdiivka, where it continued to block the northern approach to Donetsk. At the time, the typical argument that one heard from the Ukrainian side was that the Russian assault on Avdiivka was pyrrhic – that the Russians were capturing the city with exorbitantly costly “meat assaults” that would inevitably sap Russian combat power and exhaust their ability to continue the offensive.

With the full measure of the year behind us, we can definitively say that this is not the case. After the fall of Avdiivka, Russian momentum never seriously slackened, and in fact it was the AFU that appeared to be increasingly exhausted. The Ukrainian breakwater position at Ocheretyne (which had previously been their staging point for counterattacks around Avdiivka) was overrun in a matter of days, and by the early summer the frontline had been pushed out towards the approach to Pokrovsk.

The Russian thrust towards Pokrovsk led many to believe that this city was itself the object of Russian energies, but this was a misread of the operational design. Russia did not need to capture Pokrovsk in 2024 to render it sterile as a logistical hub. Simply by advancing towards the E50 highway, Russian forces were able to cut off Pokrovsk from Ukrainian positions to the south on the Donetsk front, and Pokvrovsk is now a frontline city subject to the full spectrum of overwatch from Russian drones and tube artillery.

By autumn, the Russian advance had put the Ukrainians in a severe salient, creating an unstable chain of positions in Selydove, Kurakhove, Ugledar, and Krasnogorivka. Russia’s advance from Ocheretyne onto the southern approach to Pokrovsk acted like an enormous scythe, isolating the entire southeastern sector of the front and allowing Russian forces to carve through it in the closing months of the year.

This war has turned the word “collapse” into a devalued buzzword. We are told repeatedly that one side or the other is on the verge of collapse: sanctions will “collapse” the Russian economy, the Wagner uprising of 2023 proved that the Russian political system was “collapsing”, and of course we hear that exorbitant losses have one army or the other on the verge of total failure – which army that may be depends on who you ask.

I would argue, however, that what we saw from October 2024 onward represents a real occurrence of this oft-repeated and discarded word. The AFU suffered a genuine collapse of the southeastern front, with the forces positioned in their strongpoints too attrited and isolated to make a determined defense, Russian fires becoming too heavily concentrated in ever more compressed areas to endure, and no mechanized reserve in the theater available to counterattack or relieve the incessant Russian pressure.

Ukraine does maintain enough drones and concentrated fires to limit Russian a full Russian exploitation – that is, Russia is still not able to maneuver at depth. This gave the Russian advance is particular stop-start quality, leapfrogging from one settlement and fortress to the other. More generally, Russia’s preference to use dispersed small-unit assaults limits the potential for exploitation. We have to emphasize, however, that Russian momentum on this axis has never seriously slackened since October, and many of the key Ukrainian positions were overrun or abandoned very quickly.

Ugledar is a good example: the Russians began their final push toward the town on September 24. By September 29, the 72nd Mechanized Brigade began evacuating. By October 1, Ugledar was fully under Russian control. This was a keystone Ukrainian position put in a completely untenable position and it went down in a week. One could argue, of course, that Ugledar held out for years (how then can we say with a straight face that it was captured in a week), but this is precisely the point. In early 2023 Ugledar (with the help of artillery stationed around Kurakhove) successfully repelled a multi-brigade Russian attack in months of heavy fighting. By October 2024, the position was completely untenable and was abandoned almost immediately when attacked.

The Ukrainians did no better trying to hold Kurakhove – previously a critical rear area that served as both a logistical hub and a base of fire for supporting (former) frontline strongpoints like Ugledar and Krasnogorivka. Kurakhove, now under full Russian control, will in turn serve as a base of support for the ongoing Russian push to the west towards Andriivka.

Taking the state of the front holistically, the AFU is currently holding two severe salients at the southernmost end of the line – one around Velyka Novosilka, and another around Andriivka. The former is likely to fall first, as the town has been fully isolated by Russian advances on the flanks. This is not a Bakhmut-like situation, where roads are described as “cut” because they are under Russian fire – in this case, all of the highways into Velyka Novosilka are cut by physical Russian blocking positions, making the loss of the position only a matter of waiting for the Russians to assault it. Further north, a more gentle and less strongly held salient exists between Grodivka and Toretsk. With Toretsk now in the final stages of capture (Ukrainian forces now hold only a small residential neighborhood on the city’s outskirts), the front should level here as well in the coming months.

This leaves the Russians more or less in full control of the approaches to Kostyantinivka and Pokrovsk, which are in many ways the penultimate Ukrainian held positions in Donetsk. Pokrovsk has already been bypassed several miles to the west, and the map portends a re-run of the typical Russian tactical methodology for assaulting urban areas – a methodical advance along the wings of the city to isolate it from arterial highways, followed by an attack on the city itself via several axes.

The coming months promise continued Russian advances across this front, in a continuation of what can only be regarded as the collapse of a critical front on the part of the AFU. The Russian Army is advancing to the western border of Donetsk oblast and will ferret the Ukrainians out of their remaining strongpoints at Velyka Novosilka and Andriivka, while pushing into the belly of Pokrovsk. At no point since the fall of Avdiivka have the Ukrainians demonstrated the ability to seriously stymie Russian momentum along this 75 mile front, and the ongoing dissipation of Ukrainian combat resources indicates that little will change in this regard in 2025…..

Conclusion: Debellation

Trapped in an endless news cycle, with daily footage of FPV strikes and exploding vehicles, and a dutiful cottage industry of war mappers alerting us to every 100 meter advance, it can easily feel like the Russo-Ukrainian War is trapped in an interminable doom loop which will never end – Mad Max meets Groundhog Day.

What I have endeavored to do here, however, is argue that 2024 actually saw several very important developments which make the coming shape of the war relatively clear. To briefly recapitulate:

1. Russian forces caved in Ukrainian defenses at depth across an entire critical axis of front. After remaining static for years, Ukraine’s position in Southern Donetsk has been obliterated, with Russian forces advancing through an entire belt of fortified positions, pushing the front into Pokrovsk and Kostayantinivka.

2. The main Ukrainian gambit on the ground (the incursion into Kursk) failed spectacularly, with the salient being progressively caved in. An entire grouping of critical mechanized formations wasted much of the year fighting on this unproductive and secondary front, leaving Ukrainian positions in the Donbas increasingly threadbare and bereft of reserves.

3. An attempt by the Ukrainian government to reinvigorate its mobilization program failed, with enlistments quickly trailing off. Decisions to expand the force structure exacerbated the shortage of manpower, and as a result the decay of Ukraine’s frontline brigades has accelerated.

Long awaited western upgrades to Ukraine’s strike capabilities failed to defeat Russian momentum, and stocks of ATACMs and Storm Shadows are nearly exhausted. There are now few options remaining to prop up Ukrainian strike capacity, and no prospect of Ukraine gaining dominance in this dimension of the war.

In short, Ukraine is on the path to debellation – defeat through the total exhaustion of its capacity to resist. They are not exactly out of men and vehicles and missiles, but these lines are all pointing downward. A strategic Ukrainian defeat – once unthinkable to the western foreign policy apparatus and commentariat – is now on the table. Quite interestingly, now that Donald Trump is about to return to the White House, it is suddenly acceptable to speak of Ukrainian defeat. Robert Kagan – a stalwart champion of Ukraine if there ever was one – now says the quiet part out loud:

“Ukraine will likely lose the war within the next 12 to 18 months. Ukraine will not lose in a nice, negotiated way, with vital territories sacrificed but an independent Ukraine kept alive, sovereign, and protected by Western security guarantees. It faces instead a complete defeat, a loss of sovereignty, and full Russian control.”

Indeed.

None of this should be particularly surprising. If anything, it is shocking that my position – that Russia is essentially a very powerful country that was very unlikely to lose a war (which it perceives as existential) right in its own belly – somehow became controversial or fringe. But here we are.
