In the autumn of 1941, Pechorlag (the railroad camp) had a listed population of fifty thousand prisoners, and in the spring of 1942, ten thousand. During this period not one prisoner transport was sent out of Pechorlag anywhere—so where did the forty thousand prisoners go? I have written thousand here in italics—why? Because I learned these figures accidentally from a zek who had access to them. But you would not be able to get them for all camps in all periods nor to total them up.
