Any way you count it, the figures are stark: Ukrainian casualties are running at a rate of somewhere between 6oo and 1,000 a day. One presidential adviser, Oleksiy Arestovych, told the Guardian this week it was 150 killed and 800 wounded daily; another, Mykhaylo Podolyak, told the BBC that 100 to 200 Ukrainian troops a day were being killed.

The sheer number – more than 20,000 casualties a month – raises questions about what state Ukraine’s army will be in if the war drags on into the autumn.

Ammunition is certainly running short on the Ukrainian side, again by their own admission. Vadym Skibitsky, the deputy head of Ukraine’s military intelligence, has said Ukraine is using 5,000 to 6,000 artillery rounds a day, and has “almost used up” its stockpile of Soviet 152mm standard shells. It is now relying on Nato-standard 155mm howitzers; it is unclear how many of these it has.
