Question: Was the town where Timmerman was stationed larger than the town the the IX corps was defending? Passage:On July 6, 1940, Karl Timmermann enlisted in the U.S. Army. He was stationed at Fort Lewis, Washington and assigned to the 15th Infantry Regiment of the 3rd Infantry Division. After the Japanese military attacked Pearl Harbor, his unit began training for war. The 3rd Infantry Division, with the 41st Infantry Division, were then part of IX Corps. In May 1941, the two divisions moved to the Hunter Liggett Military Reservation where June war games pitted them against Major General Joseph Stilwell's 7th Division and the 40th Division. Large scale maneuvers continued in August on the Olympic Peninsula, with IX Corps defending Tacoma, Washington until the two divisions from California could arrive to assist.
