Two Marines from the 2nd Battalion, 1st Marine Regiment during fighting at Wana Ridge during the Battle of Okinawa, May 1945. On the left, Davis Hargraves (1925-) provides covering fire with his M1 Thompson submachinegun as Gabriel Chavarria (on the right; 1926-), with a Browning Automatic Rifle, prepares to break cover to move to a different position. Wana Ridge was a long coral spine running out of northern Shuri Hill and was lined on both sides with Okinawan tombs. In addition, Japanese emplacements in the tombs and on the reverse slope of the ridge forced the Marines to carefully fight their way through the fortifications. A Japanese counterattack on the Marines on the ridge on 22 May was repelled. It is not known if this photo was taken before or after the Japanese counterattack. Note that the photographer has apparently taken the picture from a covered position behind the ridgeline.[1]

The Battle of Okinawa was characterized by brutal fighting, widespread destruction, and unimaginable suffering.

The battle began on March 26, 1945, with a massive bombardment by U.S. naval forces. Followed by an amphibious landing by U.S. Marines and Army soldiers on the western coast of Okinawa.

Furthermore, the Japanese defenders put up a fierce resistance, using a combination of conventional tactics and suicide attacks. They had built an extensive network of tunnels and caves, which they used to shelter from the American bombardment and to launch surprise attacks on the U.S. forces.

The U.S. forces were able to make steady progress inland, but the fighting was brutal and costly. The Japanese defenders fought with incredible tenacity, and the U.S. forces became often forced to fight for every inch of ground. As a result, the battle quickly became a war of attrition. Furthermore, with both sides suffering heavy casualties.

One of the most devastating aspects of the Battle of Okinawa was the impact on the civilian population. The Japanese military ordered the civilian population to remain on the island, thus many of them caught in the crossfire.

As a result, the U.S. forces became forced to take extreme measures to root out Japanese defenders from civilian areas, often resulting in the deaths of innocent civilians. In addition, the Japanese military had organized a mass suicide campaign, encouraging civilians to kill themselves rather than be captured by the Americans.

As the battle dragged on, the Japanese defenders became increasingly desperate. They launched numerous suicide attacks on the U.S. forces, using a variety of weapons, including planes, boats, and human torpedoes. The U.S. forces suffered heavy losses from these attacks, and the psychological impact was enormous.

Despite the difficulties, the U.S. forces were eventually able to secure the island.

Moreover, the battle officially ended on June 22, 1945. However, the impact of the battle became felt for years to come. The U.S. forces had suffered over 12,500 killed and 38,000 wounded, while the Japanese defenders had lost almost their entire garrison. In addition, the civilian population had suffered terribly, with an estimated 100,000 civilians killed or wounded.

The Battle of Okinawa was a brutal and costly battle, but it was also a critical turning point in the Pacific War. The capture of the island provided a secure base for the U.S. forces to launch the final assault on Japan, and it also demonstrated the incredible strength and determination of the Japanese defenders. Lastly, the battle was a reminder of the terrible cost of war and the need to work for peace and reconciliation.
