Wartime History
In preparation for the 1st Squadron, 12th Cavalry's attack on Koruniat, which had earlier been suspected of harboring naval guns, PT boats and a rocket boat as well as artillery took the island under fire. Bombing and strafing by the RAAF and heavy mortar fire from Mokerang Point also preceded the assault. On April 1, 1944 the US Army, 12th Cavalry, 1st Squadron, reinforced, made an amphibious landing, transported in native canoes on Koruniat and Ndrilo. No Japanese were found on Koruniat. On April 2, the 1st Squadron returned to Lombrum.

On April 4, 1944 the 5th Cavalry began constructing a semi-permanent bivouac on Koruniat Island. Troops of the 1st Brigade would settle down to housekeeping, rehabilitation, and training, with existence in the tropics made more bearable by the arrival of refrigeration, bakery, and laundry companies.
