It's strange when you visit Europe today, trying to imagine all the WWII devastation.
The hill leading up to Monte Casino Italy, is still littered with rusting trucks and armor. The Cologne Cathedral has a WWII display. It was not destroyed, but was heavily damaged. I think we left enough of it standing, to use as a landmark for bombing. The Remagen bridge across the Rhine is absolutely spooky looking. That's the bridge that was not destroyed by Germany when they were retreating. All that remains are the anchorage towers, but a lot of our soldiers died there, because we tried to overload the bridge, with men and equipment headed into Germany, and the stress collapsed the bridge.
