Ukraine and Russia ‘compete to be last army standing’ as Donbas deaths mount

Three and a half months into the Ukraine war and what was once a fight across the whole country feels like it has become concentrated on Sievierodonetsk, the centre of weeks of combat that looks likely to have cost hundreds of lives as Russia appears to be closing in.

Ukrainian insiders estimate that Russia now has 120 battalions inside Ukraine, but such has been the attrition so far, their strength is perhaps 40% or 50% of a normal full complement of about 800. Half that total force is concentrated in the eastern Donbas region - and a third, so 40, around Sievierodonetsk.

It demonstrates the level of concentration Russia needs to make progress, blasting the area with a mix of air, artillery, mortar and even rocket-propelled grenade strikes before advancing over the destruction that remains. All for a city that, while it may be in the frontline, is not militarily strategic.

Ukraine says its goal is simply to hold up the Russians, inflict losses on the larger invading army and reduce their morale. At one point over the weekend the defenders managed a short-lived counterattack, but this seems to have provoked an even more intense bombardment from the invaders.

A similar fight looms for neighbouring Lysychansk across the Siverskyi Donets River that Russian forces have had difficulty crossing. It lies on higher ground than Sievierodonetsk, and is the final city in the Luhansk region held by Ukraine. Ukraine holds more of the neighbouring Donetsk oblast, the other half of the Donbas. Kramatorsk, the most likely final target, is about 40 miles from Lysychansk.

A key question is whether Ukraine can cope with the losses it is sustaining. Estimates vary, but Oleksiy Arestovych, a high-profile Ukrainian military analyst and presidential adviser, said "up to 150 troops a day were being killed and 800 wounded".

That is higher than the 50-100 a day acknowledged by President Volodymyr Zelenskiy, and a high rate of wounded that could reflect poor access to battlefield medicine, or the difficulty of evacuation - or is perhaps an overestimation. But there is also likely to be a similar rate of casualties on the Russian side, amid indications the invading forces are approaching the point of exhaustion.
