Thank you for the warm welcome, Larry! I do recall my great uncle telling me about buliding a pontoon bridge across the Rhine River at Worms, Germany, and later on, picking up an abandoned German rifle and going deer hunting to provide some venison for his comrades. At the time, I found this story interesting as at that time, I was using a German K98 Mauser rifle as a deer hunting rifle. I still have the rifle, and everytime I get it out of the rack, I think of Charlie and his hunting trip in Germany.
As far as research goes regarding the 305th, I've sent off to the Personnel Records Center in St. Louis for the records of a Captain Gordon Queen who was KIA serving in the 305th Engineer Battalion in France. I don't even know what company he was with, but hopefully the records will arrive shortly.
