To me, one of the most interesting aspects of the Stalingrad battle was the treatment of the surrendered 6th German army. Many thousands died along the frozen march to Siberia.
Many more died there until a very few—I believe the number was under 5000—were finally sent home in the mid 1950’s. The Soviets were not signers of the Geneva accords pertaining to the treatment of POW’s.
I do not know if any of those march-to-Siberia survivors are alive today.
I believe some of the wounded who were flown out of the besieged German pocket in Dec ‘42 and Jan ‘43 are still living.
Also interesting is how Germans treated the Russian POW’s.
Trying to find information about German POWs in Russia prior to the internet was almost impossible.
I had always been interested in what happened to the millions of Germans who were sent East after the war. Treatment, conditions, deaths etc.
There was testimony made by a former Russian prisoner of the gulags to congress back in the 1970s. He stated that after the 1956 release of German POWs there were still many in Russia. Quite a few on Wrangel Island.
But that may have just been rumor. Who knows.
