With a reserve commission in the army (like Quentin and Archibald), soon after World War I started, Ted was called up. When the United States declared war on Germany, Ted volunteered to be one of the first soldiers to go to France. There, he was recognized as the best battalion commander in his division, according to the division commander. Roosevelt braved hostile fire and gas and led his battalion in combat. So concerned was he for his men's welfare that he purchased combat boots for the entire battalion with his own money. He eventually commanded the 26th Regiment in the 1st Division as a lieutenant colonel. He fought in several major battles, including America's first victory at Cantigny.
