W. Stilwell. Most of the early troops in the division were conscripted as a part of the US Army's first peacetime military draft. The 7th Division was assigned to III Corps of the Fourth United States Army, and transferred to Longview, Washington, in August 1941 to participate in tactical maneuvers. Following this training, the division moved back to Fort Ord, California, where it was located when the Japanese attack of Pearl Harbor caused the United States to declare war. The formation proceeded almost immediately to San Jose, California, arriving 11 December 1941 to help protect the west coast and allay civilian fears of invasion. The 53rd Infantry Regiment was relieved of assignment to the 7th Division and replaced with the 159th Infantry Regiment, newly deployed from the California Army National Guard. For the early parts of the war, the division participated mainly in construction and training roles.

The 7th Infantry Division began rigorous amphibious assault training under US Marines from the Fleet Marine Force, before being deployed to fight in the Pacific theater instead of Africa. USMC General Holland Smith oversaw the unit's training. Aleutian Islands Elements of the 7th Infantry Division first saw combat in the amphibious assault on Attu Island, the westernmost Japanese entrenchment in the Aleutian islands chain of Alaska. Elements landed on 11 May 1943, spearheaded by the 17th Infantry Regiment. The initial landings were unopposed, but Japanese forces mounted a counteroffensive the next day, and the 7th Infantry Division fought an intense battle over the tundra against strong Japanese resistance. The division was hampered by its inexperience, lack of winter clothing, and poor weather and terrain conditions, but was eventually able to coordinate an effective
