Major General

Unit:

1st Marine Division "The Old Breed", U.S. Marine Corps

Awarded for:

Operation Detachment

"For exceptionally meritorious service to the Government of the United States in a duty of great responsibility as Commanding General of the FIRST Marine Division during the attack and occupation of Okinawa Shima in the Ryukyu Chain, from 1 April 1945 to 21 June 1945. A brilliant tactician, Major General Del Valle effected the strategic landing of his units on the western shores of Okinawa on 1 April and immediately initiated a vigorous offensive, slashing through Japanese resistance and cutting across the island to seize, in 72 hours of swift, aggressive action, a segment of enemy held territory extending from the west to the east coast. Turning southward, he advanced his forces toward the formidable system of natural and man-made defenses comprising the ramparts of the hostile stronghold at Shuri to find that heavy mud precluded the use of many supporting weapons and made supply almost impossible except by air. Analyzing the situation with keen military acumen, he organized his attack plans with unerring judgment and laid constant, bitter siege to the enemy until the defending garrison was reduced and the elaborate bastion destroyed. An indomitable leader, he continued to wage a relentless battle, attacking and violently overthrowing a series of heavily fortified, mutually supporting ridge positions to the extreme southern most tip of the island. Undaunted by the deadly accuracy of enemy gunfire, he repeatedly visited the fighting fronts, maintaining close tactical control of operations and rallying his weary but stout-hearted Marines to heroic effort during critical phases of the long and arduous campaign. By his superb general-ship, outstanding valor and tenacious perseverance in the face of overwhelming opposition, Major General Del Valle contributed essentially to the conquest of this fiercely defended outpost of the Japanese Empire and his decisive conduct throughout the savage hostilities reflects the highest credit upon himself, his gallant command and the United States Naval Service."
