Helping to ensure that the Marines would stay on shore once they landed was a host of unheralded support troops who had been struggling since daylight to manage the flow of vital supplies to the beaches. Now, as W-Day’s darkness approached, the 4th Ammunition Company, a black Marine unit, guarded the brigade’s ammunition depot ashore. During their sleepless night, these Marines killed 14 demolition-laden infiltrators approaching the dump.

A Japanese cave position on the reverse slope of Chonito Ridge offered protection for the enemy from the prelanding bombardment and enabled them to reoccupy prepared positions from which they could oppose the advance of the 3d Marines.

Faulty communications delayed the order to land the Army’s 305th Regimental Combat Team (Colonel Vincent J. Tanzola), elements of the assault force, for hours. Slated for a morning landing, the 2d Battalion of Lieutenant Colonel Robert D. Adair did not get ashore until well after nightfall. As no amtracs were then available, the soldiers had to walk in from the reef. Some soldiers slipped under water into shellholes and had to swim for their lives in a full tide. The rest of the 305th had arrived on the beach, all wet, some seasick, by 0600 on W plus-1.

Medal of Honor Recipients

Private First Class Luther Skaggs, Jr.’s Medal of Honor citation reads as follows: “For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as squad leader with a mortar section of a rifle company in the 3d Battalion, 3d Marines, 3d Marine Division, during action against enemy Japanese forces on the Asan-Adelup beachhead, Guam, Marianas Islands, 21–22 July 1944. When the section leader became a casualty under a heavy mortar barrage shortly after landing, Private First Class Skaggs promptly assumed command and led the section through intense fire for a distance of 200 yards to a position from which to deliver effective coverage of the assault on a strategic cliff. Valiantly defending this vital position against strong enemy counterattacks during the night, Private First Class Skaggs was critically wounded when a Japanese grenade lodged in his foxhole and exploded, shattering the lower part of one leg. Quick to act, he applied an improvised tourniquet and, while propped up in his foxhole, gallantly returned the enemy’s fire with his rifle and hand grenades for a period of 8 hours, later crawling unassisted to the rear to continue the fight until the Japanese had been annihilated. Uncomplaining and calm throughout this critical period, Private First Class Skaggs served as a heroic example of courage and fortitude to other wounded men and, by his courageous leadership and inspiring devotion to duty, upheld the high traditions of the United States naval service.”
