Finally sent to France, Lt. Roosevelt first helped in setting up the large Air Service training base at Issoudun. He was a supply officer and then over time ran one of the training airfields. Eventually he became a pilot in the 95th Aero Squadron, part of the 1st Pursuit Group. The unit was posted to Touquin, France and, on July 9, 1918, Saints, France. During the time that he was flying from Saints, he was billeted just half a mile away at Melina Thibault's home in Mauperthuis, France where he roomed with supply officer Ed Thomas. Roosevelt had one confirmed kill of a German aircraft he shot down on July 10, 1918. Four days later, in a massive aerial engagement at the commencement of the Second Battle of the Marne, he was himself shot down behind German lines.
