, and warned by intelligence of the storm to come, utterly defeated a massive and sustained Japanese counter-attack, which began on 7 March 1944. Despite ample warning and thorough defensive preparations, the battle soon degenerated into a bitter, close-quarters infantry affair, with artillery restricted by the need to avoid friendly troops and tanks unable to reach the scene. The 37th and Americal Divisions stood firm, and by March 25, the Japanese were forced to retreat. It was the last Japanese ground offensive in the South Pacific.

The Division Returned to U. S. on 1945-11-21, and was inactivated on 1945-12-12. It was reactivated on 1954-12-01 as the 23rd Infantry Division, retaining the name "Americal" as part of its official designation, and served in the Panama Canal Zone

As new U.S. brigades arrived in Vietnam, they were assigned to Task Force Oregon, which was re-designated the 23rd Infantry Division (Americal). The Division was composed of the 11th, 196th, and 198th Light Infantry Brigades and divisional support units.

In spite of a large number of successful operations, the Division's history is marred by such incidents as the massacre at My Lai and the overrun of FSB Mary Ann, as well as the fact that two of its brigades, the 11th and 198th, arrived as the division was formed in 1967 without prior combat experience and inadequate unit training.

The 198th and 11th Brigades were withdrawn from Vietnam in November, 1971, and the Division was inactivated. The 196th Brigade was reconstituted as a separate brigade and remained in Vietnam until June 29, 1972, the last major combat unit to be withdrawn. Its 3rd Battalion 21st infantry was the last battalion to leave Vietnam, on August 23, 1972.

Insignia


The shoulder sleeve insignia was originally approved for the Americal Division on December 20, 1943. It was redesignated for the 23d Infantry Division on November 4, 1954. On December 14, 1967 the Distinctive Unit Insignia was approved.

The shoulder sleeve insignia's four white stars on a blue field are symbolic of the Southern Cross under which the organization has served. The blue color stands for infantry.

On the Distinctive Unit Insignia, the saltire (cross of St. Andrew) alludes to New Caledonia in the Southwest Pacific where the Division was created and first activated on May 27, 1942. Each of the four stars stands for four World War II campaigns (Guadalcanal

In view of the Division's origin and outstanding service in World War II and inasmuch as it was one of the few U.S. Army Divisions to bear a name instead of a number, the Division's former name "Americal" has been taken as a motto, the association with that name being both inspirational and of historical military significance.
