The 40th Infantry Division's first oversea assignment was the defense of outer islands of Hawaii, where it
arrived in September 1942. Training continued as defensive positions were improved and maintained. In
July 1943 the Division was concentrated on Oahu, and relieved the 24th of the defense of the North
Sector. Relieved of the North Sector in October 1943, the 40th entered upon a period of intensive
amphibious and jungle training. On 20 December 1943, the first units left for Guadalcanal, and
by mid-January 1944, movement was completed, and the Division prepared for its first combat
assignment. On 24 April 1944, it left Guadalcanal for New Britain. The Regiments of the Division took
positions at Talasea on the northern side of the island, at Arawe on the southern side, and at Cape
Gloucester near the western end. Neutralization of the enemy was effected by patrols. No major
battle was fought. Heavy rain and mud were constant problems. The 40th was relieved of
missions on New Britain, 27 November, and began training for the Luzon landing. Sailing from
Borgen Bay, 9 December 1944, the Division made an assault landing at Lingayen, Luzon, under
command of XIV Corps, on 9 January 1945. Seizing Lingayen airfield, the Division occupied
Bolinao Peninsula and San Miguel, and advanced toward Manila, running into heavy fighting in the
Fort Stotsenburg area and the Bambam Hills. Snake Hill and Storm King Mountain were taken in
February and the 40th was relieved, 2 March. Leaving Luzon, 15 March, 1945, to cut
behind the Japanese, the Division landed on Panay Island on the 18th and knocked out
Japanese resistance within 10 days, seizing airfields at Santa Barbara and Mandurriao. On 29 March, it
landed at Pulupandan, Negros, advanced through Bacolod toward Talisay, which it
secured by 2 April 1945. After mopping up on Negros Island, the Division returned to
Panay in June and July 1945. In September 1945, the Division moved to Korea for occupation duty.
