120MM GUN BUNKERS: Overlooking the cliffs of the East Boat Basin were three large concrete bunkers. Only one was still standing, with the other two destroyed by American naval and aerial bombardment. Standing atop this bunker you could see directly down the flank of the landing beaches. This area, the East Boat Basin was well fortified with heavy guns such as the 120MM guns that were once housed in these very bunkers. Behind these bunkers were a series of mortar positions that rained down upon the Marines and Sailors on the beach.
