My grandfather was in Duren and also was in battle at the roer river.and there was also mentioned about the pennisular of crozon where there was a general in charge of the defense of Brest.I believe he was in the army and was wounded in germany. He ended up blind and was at Valley forge and later went to the olds faarm convalescent hospital in connecticut. he was in ward one for the legally blind. he did recieve 3 purple hearts for sharpnel wound to his leg, stomach, and blindness. Was wondering how you find out what regiment or infantry he was in?
