The fields are flat and generally featureless, and residents of the local villages have evacuated their homes. However, this area is of critical importance because it serves as a gateway to the city of Kherson. A metropolitan center of about 300,000 inhabitants, it is the only regional capital that the Russians managed to capture – making it an invaluable military prize. By capturing the city, the Ukrainians will effectively drive the enemy from the western side of the Dnipro River, strengthening the momentum they have built up in recent weeks. Their forces are about 30km from the outskirts of the city and we were driven into a series of narrow walled trenches that form the Ukrainian side of the current front line.

We walked across a section of open ground and found a pair of gunners at the edge of a shallow trench. We were told that this spot had recently been captured by the Russians. “Browning gun, Germany. I can show you,” said one, as he gripped the grips of his heavy machine gun. “If you look ahead, 11 o’clock, there’s a building there, and our intelligence now tells us that there are Chechens inside.” Chechen fighters, led by Ramzan Kadyrov, a prominent Russian supporter of Vladimir Putin, are actively involved in this war, developing a terrifying reputation for brutality. “Have you used (the gun)?” I asked. “Yes, we’ve used it and successfully – it’s indefensible.
