Thanks alot gentlemen! That's a beginning.
I'm focusing at the area around Vienna, Austria during the time period April - May 1945. Several local historian describe an air attack by sovjets on April 17th, 1945. They hit railwaystation and small military objects in several small towns south east of Vienna.
