er ... No my mother-in-law is no longer with us, nor, sadly, are most of the other relatives who lived through the war. It is possible that the robbery and rape stuff was all rumour, but based on what little she did say, the Poles detested the Russians even more than the did the Germans.
We do know that MIL came from an area where there were a fair number if Jews before the war (she spoke Yiddish, as we discovered after she died). We are also fairly sure that she had some kind of nursing training during the war, but never could get her to tell us the details.
We also know that her father (who died many years before I met her) slipped away to live in the forest when the Germans arrived because he knew he would be conscripted by them. He did come out of hiding when the Germans threatened to kill his family and wound up in some kind of Polish batallion fighting (very reluctantly) for the Germans. He, along with some of his friends, surrendered to the Americans at the earliest opportunity, and eventually wound up over here.
It would have been good to learn their stories, but it's no longer possible, and the few people we know who did live through the war are very reluctant to talk about it.
