My great uncle was gassed and wounded by shrapnel during the Meuse-Argonne campaign and, according to his daughters, abandoned on the battlefield for a while. He was eventually found, patched together and sent home, after his family was told he was missing in action. (The gas injury took its toll and he died from lung problems.) I have basic information about his unit -- company, regiment and Division -- but I would like to find out a little more about his wounds and possibly where he was treated in France. I'm assuming he was awarded the Wound Chevron, the predecessor to the Purple Heart. Would those records most likely have been destroyed in the infamous 1973 fire or are there other sources to check? I am currently living in France and would like to take advantage of my proximity to the battlefields and surrounding towns.
