During the war, the Military Intelligence Service Language School (MISLS), as it came to be called, grew dramatically. After the attack on Pearl Harbor Japanese-Americans on the West Coast and the Hawaii Territory were moved into internment camps in 1942. Because of anti-Japanese sentiments the Army did a nationwide survey for the least hostile environment and moved the school to a former Minnesota WPA camp named Camp Savage. By 1944 the school had outgrown those facilities and moved to Fort Snelling close by. There the school grew to 125 classrooms with over 160 instructors. Over 6,000 of its graduates served in the Pacific during the war and occupation of Japan.
