He explained the gist of the documentary being filmed recounting the historical details of some of World War II's bloodiest battles in the Pacific Theater:
"On D-Day (Pacific Theater), 15 Sept.,1944, five infantry battalions of the 1st Marine Division's 1st, 5th, and 7th Marines, in amphibious tractors (LVTs) lumbered across 600 to 800 yards of coral reef ... reportedly smashed Peleliu in the Palau Island group, and moved toward five selected landing beaches," he wrote. "That westward anchor of the 1,000-mile-long Caroline archipelago was viewed by some U.S. planners as obstacles, or threats, to continued advances against Japan's Pacific empire.
"The Marines in the LVTs had been told that their commanding general, Maj.Gen. William H. Rupertus, believed the operation would be tough, but quick, in large part because of the devastating quantity and quality of naval gunfire and dive bombing scheduled to precede their assault landing," Cunningham wrote. "On some minds were the grim images of their sister 2nd Marine Division's bloody assault across the reefs at Tarawa, many months earlier. But 1st Division Marines, peering over the gunwales of their landing craft saw an awesome scene of blasting and churning earth along the shore."
Cunningham — the son of Justice Bill Cunningham and his wife, Paula — is captain of the Alucia, the ship from which "The Deadliest Catch," also is filmed.
