U.S. Navy Department (April 7, 1945)
CINCPOA Communiqué No. 324
On April 6 and 7 (East Longitude Dates), the enemy attempted strong counterattacks against our forces operating in the vicinity of Okinawa.
During the late afternoon and evening of April 6, a large force of enemy aircraft attacked our ships and shore installations in the vicinity of Okinawa. One hundred sixteen of these enemy aircraft were destroyed – 55 by our fighters and the remainder by our anti-aircraft fire. The attacking enemy aircraft pressed their attacks in with desperation and succeeded in sinking three of our destroyers and damaging several destroyers and smaller craft. No larger fleet units were hit.
Early on April 7, Navy search aircraft of Fleet Air Wing One sighted an enemy surface force which had left the Inland Sea and passing south of Kyushu had headed into the East China Sea. The force included the large battleship YAMATO, the most powerful ship left in the Japanese Navy, an AGANO-class light cruiser, one other small light cruiser or large destroyer, and a number of destroyers. A fast carrier task force commanded by VADM Marc A. Mitscher steamed toward the enemy at high speed and during the middle of the day brought the Japanese Force under air attack.
Our carrier aircraft which had destroyed 245 enemy aircraft on April 6, met no opposition over the Japanese ships but did meet heavy anti-aircraft fire. At a point about 50 miles southwest of Kyushu they sank the YAMATO, the light AGANO-class cruiser, the small cruiser and three destroyers. Three other destroyers were left burning. About three destroyers escaped from this attack.
The YAMATO was hit by at least eight torpedoes and eight heavy bombs. All the enemy ships were heavily strafed with rockets and machine guns.
Our carriers lost seven aircraft in this action. During minor contacts on April 7, they and their aircraft shot down 30 enemy aircraft. The task groups participating were commanded by RADMs F. C. Sherman, USN; A. W. Radford, USN; G. F. Bogan, USN, and J. J. Clark, USN.
The Marine III Amphibious Corps on Okinawa moved forward steadily in the northern sector throughout the afternoon of April 6. By 1800, it had made advances which placed its front lines across Ishikawa Isthmus from Chuda on the west coast to the mouth of the Kinbaru River on the east coast. In the south, strong enemy resistance developed during the day. From its strong defensive positions the enemy employed machine gun, small arms, mortar and artillery fire against the XXIV Army Corps throughout April 6, and the following night. Army troops along the East Coast in the southern sector advanced about 2,000 yards during the afternoon of April 6, and occupied the town of Tsuwa. The enemy in the south was brought under heavy fire by our artillery throughout the day.
Search aircraft of FlAirWing One attacked airfields in Kyushu, destroying four fighters on the ground, probably destroying three others and damaging about 15 more by strafing.
Liberators of the 7th Army Air Force bombed dock installations and buildings at Truk in the Carolines on April 5.
Neutralizing raids on enemy bases in the Marshalls were continued on April 5 by planes of the 4th Marine Aircraft Wing.
