I'm just saying: they walked to Stalingrad so why the Soviets should change their habits. Just let them keep walking. But, of course I know and all these soldiers at the both sides knew much better that the life in south-east Russia wasn't a picnic. There were no trains in Stalingrad - the Germans destroyed anything they could, along with the railway station. The 6th army have eaten their own horses. They had no other option but to walk away to wait for transportation to their final destination in other parts of the USSR. Those who want to learn more may find more information in Beevors' "Stalingrad - The Fateful Siege" from page 414 on. Now, let's get back to transportation methods and trains. To illustrate how the life of a soldier can bring bitter surprises, here is a short passage from Beevor, pp. 415: ... After the experience of Beketovka, they were certain that the worst must be over, and the prospect of movement and change had its own appeal, but they soon discovered their mistake. Each railway wagon, with up to a hundred men forced into each one, had a single hole in the middle of the floor as a latrine. The cold was still terrible, but thirst was again the worst affliction, for they were given dried bread and salt fish to eat, but little water. So desperate did they become, that they licked the condensation frozen to metal parts inside the truck. At stops men allowed out often could not resist seizing handfuls of snow and forcing it into their mouths. Many died as a result, usually so silently that their comrades only realized that they had gone much later. Their corpses were then stacked by the sliding door of the wagon, ready for unloading. 'Skolko kaputt?'' Soviet guards would shout out in their pidgin-German at stops. 'How many dead?'
