Army landing on Biak, Americans occupied portions of the cave while the rest was held by the Japanese and used to harass the landing force and bombard Mokmer Airfield (Mokmer Drome). To eliminate the threat, American forces began probing the cave system for entrances and weaknesses.

On July 7, 1944 during the early morning, the U. S. Army began attacking the cave and bombing and bombarding of the area. The attacks culminated with pumping drums of gasoline into cave entrances that was ignited. Inside, an estimated 3,000 Japanese were killed in the attacks.
