Packed with exhausted Ukrainian soldiers with clenched jaws, the truck drives away at full speed. The troops from the 81st brigade have just received an order to withdraw from the eastern front where Russian forces advance. The brigade walked 12 kilometres (7.5 miles) Saturday, camouflaged in the woods and under crossfire, until their point of retreat at Sviatoguirsk. For a month, the 81st — whose motto is “always first” — battled to push back the Russian advance in Ukraine’s eastern Donbas region where Moscow’s troops move forward slowly, taking villages one by one. “Everyone understands that we must guard the line here, we cannot let the enemy move closer, we try to hold it with all our force,” says lieutenant Yevgen Samoylov, anxious that the unit could be hit by Russian fire at any point. “As you can hear, the enemy is very, very near,” he says, pointing to the sky. The line of Russian tanks is on the other side of a hill, around seven kilometres (4.3 miles) away. At 21 years old, Samoylov, an officer from the Odessa military academy, finds himself managing 130 conscripts, often twice his age. “It’s my first war. I was supposed to graduate in four months, but they sent me here,” says the baby-faced officer with a short black beard. Samoylov, who goes by the nom de guerre “Samson”, never leaves his red notebook alone. He takes notes of every movement, but also each request and remark by the soldiers whom he always addresses with a soft voice. The unit swung into action on February 23, a day before Russia launched the invasion. At the start of the war, they spent a month defending Izium, which fell on April 1, before joining the fighting around the village of Oleksandrivka. “Some really difficult battles,” says the quiet Samoylov. In this brigade, like the others, they don’t say how many people have been killed. When the subject comes up, Samoylov’s gaze becomes misty. The pain is raw. A deadly silence takes over the military truck during the drive to the abandoned building where the soldiers will stay during their week of rest. When the convoy passes a truck loaded with long-range missiles dashing to the front, the soldiers automatically make a “V” sign for victory with their fingers before fixing their gaze once more on their feet or the horizon in silence. On arrival at the base, the soldiers unload their weapons, remove their kit and immediately go into one of the dilapidated rooms without electricity where they undergo a medical examination after returning from the front.
