It is around midnight in Donbas, eastern Ukraine, and the first emergency ambulance of the night is charging 75mph down a single carriageway road from the frontline. Inside, under the care of two watchful medics, is Ihor, an unconscious soldier wounded from the battle of Chasiv Yar, with shrapnel, perhaps from a mine, in his abdomen.
The medics’ task is to complete the last leg of evacuation from the battlefield, which involves Ihor and tonight’s most serious casualties being taken to a hospital in the safe central city of Dnipro. Four ambulances are following on a bumpy high-speed run that takes three hours down roads largely deserted because of the 9pm curfew, the full single beds creaking and bouncing as they go.
