Wartime History
During September 1944, the Japanese defended this feature. From their positions in and on the hills, the Japanese were able to interdict American movements along the East Road or West Road. The southern slopes overlooked the landing beaches and Peleliu Airfield. The southern slopes of Umurbrogol were attacked by the 1st Marine Division under Puller with 2/7 attached. By September 19, 1944 the southern slopes were secured but the Japanese were still able to harass the Americans.

On September 20, 1944 the 7th Marines took over the offensive and between September 21-29, 1944 attempts were to advance from the south to north. Despite American artillery, tank and air support, enemy positions inside the hills and canyons were untouched and able to fire down on advancing Marines.

The Marines were determined to break the defense but their offensive devolved into a long siege to reduce the defensive position. Attacked by U. S. Marines including the 7th Marines and U. S. Army 81st Division until November 27, 1944 (D plus 73) when the defenders were finally neutralized.
