Hi Alex:
I thought Werner's question was ligitimate.
- Austria is a big place, even in April 1945.
- There were lots of actions going on and flowing in from Germany, CZ, Hungary and Italy
- Records at this date are extremely sparse unless there are FBs or KTs available.
So, you might be a little more specific as your information allows. If you do not have it, be patient. You are asking for "rare" information.
