“If there was any wood to burn in the small bunker stoves, smoke emerged from little chimney stacks, made from empty food tins rammed together. Duckboards, tables, even bunks as men died, were broken up as fuel. The only substitute for real warmth was a fug, created with packed bodies and tarpaulins, but men still shivered uncontrollably. The comparative heat did little more than stir their lice into activity, and drive them wild with itching. They often slept two to a bunk with a blanket over their heads in a pathetic attempt to share body heat. The rodent population swelled rapidly on a diet of dead horses and humans. Out in the steppe, mice became voracious in their search for food. One soldier reported that mice ‘had eaten two of his frozen toes’ while he was asleep.” – Antony Beevor, Stalingrad
