During the Battle of Okinawa in the Pacific War, an American scout soldier who was in the valley of the Oroku Peninsula and was killed or wounded lies beside an American soldier who invaded the Oroku Peninsula, where the Japanese naval air station was located, on June 4, 1945.

     During the Battle of Okinawa in the Pacific War, U.S. forces landed from Oroku Beach southwest of Naha, Okinawa, on June 4, 1945, and invaded the Oroku Peninsula, where the Japanese Naval Air Station was located. Beside the U.S. scouts lay a U.S. soldier who had been killed or wounded in the valley of the Oroku Peninsula, and as of June 4, the Japanese naval forces were struggling to attack and defend almost half of the Oroku Peninsula.

　Japanese naval forces returned to their old positions at Oroku Naval Air Station from Maepyeong in the south on the night of May 28, 1945. American forces landed on Oroku Beach from an amphibious assault on June 4, increasing the speed of the invasion. They advanced to the Oroku Naval Air Station position defended by the Japanese naval forces. The IJN's fighting force was small and poorly equipped. The IJN took separate action from the Army garrison and confined itself to the Oroku area to fight the invasion, and by the retreat on May 26, it had destroyed its remaining heavy weapons and had only about 4,000 men. By June 5, the Japanese naval forces were surrounded by American troops and were unable to retreat. On June 6, Rear Admiral Minoru Ota sent a telegram to all parts of the country, saying, "The people of Okinawa are fighting this war, and I hope that the people of Okinawa will be granted special favor in future generations.

  　The U.S. invasion of the Oroku Peninsula was met with fierce resistance from Japanese naval forces, which suffered heavy losses, and on June 11, the U.S. forces surrounded the positions of the Japanese naval forces. The siege of the Oroku Peninsula lasted for about 10 days, resulting in approximately 1,608 casualties among the U.S. forces. Despite the meager weaponry of the Japanese naval forces, the casualty rate of the American forces far exceeded that of the Shuri Offensive. The Japanese naval forces were annihilated and crushed by suicide when a group of American tanks attacked the cave headquarters on June 11. In the naval headquarters dugout, five of the staff officers committed suicide together on June 13. After overrunning the Oroku area, the U.S. forces conducted a special search of the cave command center in the bunker of the Japanese naval forces. The bodies of hundreds of Japanese soldiers who had committed suicide lay there. In the central room of the bunker, they found the corpses of five senior officers. The hill where the bunker of the headquarters of the Japanese naval forces was located was named "Admiral's Hill. In the Kosoku area, on June 12 and 13, for the first time in the Battle of Okinawa, about 159 Japanese soldiers surrendered en masse and were taken prisoner.
