The 43rd Infantry Division was a formation of the United States Army from 1920 to 1963, serving in the Pacific during World War II.

The staff participated in the First Army command post exercises at Camp Dix, New Jersey, in 1931 and 1934, and at Fort Devens, Massachusetts, in 1936 and 1937.

During that camp, training was conducted at the squad and platoon level due to the relative inexperience of the units’ soldiers.

The next opportunity for the 43rd Division to function as a complete unit came in August 1935 when it participated in the First and Second Corps Area phase of the First Army maneuvers at Pine Camp, New York.

In 1939, the “Winged Victory” Division again participated in the First Army maneuvers, this time at Plattsburg, New York, as part of the provisional I Corps.

The 43rd Division's last major training event before induction was the First Army maneuvers near Canton, New York, in August 1940.

It was inducted into federal service at home stations on 24 February 1941 and ordered to move to Camp Blanding, Florida, where it arrived on 13 March 1941.

The division staged for shipment overseas at Fort Ord, California, on 6 September 1942 and departed San Francisco on 1 October.

The division arrived in New Zealand on 23 October 1942, prior to being committed to combat in the South West Pacific Theater under the command of General Douglas MacArthur.

Vela Cela and Baanga were taken easily, but the Japanese resisted stubbornly on Arundel Island before withdrawing, 22 September.

It engaged in patrols and reconnaissance at Tadji and along the Drinumor River, 25 July, and took the offensive, 8 August 1944, ending organized resistance on the 25th.

On 9 January 1945, the 43rd made an assault landing in the San Fabian area, Lingayen Gulf, Luzon.

The division troops were then moved to Camp Stoneman near Pittsburg, California, and arrangements were made to send each man to the Army separation center nearest his home.

During the Korean War, the 43d Division was again ordered into active Federal Service on 5 September 1950 and was moved to Seventh United States Army, VII Corps in West Germany in 1951.
