Invasion of Iwo Jima

Invasion of Iwo Jima. The Battle of Iwo Jima was a major military campaign conducted by the United States Marine Corps against the Imperial Japanese Army during the final stages of the Pacific War. Fought from 19 February to 26 March 1945, the battle resulted in the capture of the strategically important island of Iwo Jima, which provided a critical airbase for United States Army Air Forces operations against the Japanese archipelago. The intense fighting and iconic photograph of the Raising the Flag on Iwo Jima have cemented the battle's place in American military history.

Background

Following the successful Marianas and Palau Islands campaign, American military planners sought an advanced base to support the strategic bombing campaign against Japan and provide emergency landing fields for damaged B-29 Superfortress bombers. The Volcano Islands, particularly Iwo Jima, were identified as a key objective due to their location roughly halfway between the Mariana Islands and Tokyo. The island's two Japanese airfields, Central Field and Motoyama Airfield No. 2, were used by the Imperial Japanese Navy Air Service to launch raids against American bases. The Joint Chiefs of Staff approved the operation, codenamed Operation Detachment, as a necessary precursor to the planned invasion of Okinawa.

Planning and preparation

American planning was overseen by the V Amphibious Corps under Lieutenant General Holland Smith, with detailed operational command given to Major General Harry Schmidt. The invasion force, comprising the 3rd Marine Division, 4th Marine Division, and 5th Marine Division, underwent extensive training in Hawaii and the Marshall Islands. The United States Navy assembled a massive fleet, including battleships like the USS ''Tennessee'' and aircraft carriers from Task Force 58, to provide naval gunfire and air support. Japanese commander Lieutenant General Tadamichi Kuribayashi abandoned traditional beach defenses, instead constructing a vast network of interconnected tunnels, bunkers, and fortified positions, including Mount Suribachi, designed for a protracted battle of attrition.

Battle

The initial naval bombardment began on 16 February 1945, but failed to destroy many Japanese fortifications. The first Marine landings on the southeastern beaches on 19 February met initially light resistance, which intensified as forces moved inland. Fierce fighting occurred at Mount Suribachi, which was secured on 23 February, an event immortalized by Associated Press photographer Joe Rosenthal. The battle then shifted north to the main Japanese defenses in the "Meat Grinder" complex, which included Hill 362A and the Amphitheater. The 3rd Marine Division entered the fight to relieve battered units. Organized resistance ended with the final Banzai charge on 26 March, though isolated holdouts continued for months.

Aftermath

American casualties were exceedingly high, with nearly 7,000 killed and over 19,000 wounded, making it one of the costliest battles for the United States Marine Corps. Japanese losses were almost total, with only about 216 of the original garrison taken prisoner. The island was rapidly transformed into a major airbase; the first emergency landing of a B-29 Superfortress occurred even before the battle concluded. Iwo Jima Air Base subsequently supported the Air raids on Japan, including the Bombing of Tokyo, and saved an estimated 24,000 airmen. The battle demonstrated the Japanese military's commitment to the Kantai Kessen strategy of inflicting maximum casualties, which directly influenced planning for the anticipated Operation Downfall.

Legacy

The battle became a powerful symbol of sacrifice and determination, epitomized by the Raising the Flag on Iwo Jima photograph and the subsequent Marine Corps War Memorial in Arlington, Virginia. Several participants, including John Basilone and Daniel Inouye, were celebrated as heroes. The battle has been depicted in numerous films, such as Sands of Iwo Jima and Letters from Iwo Jima, and is a central subject in the historiography of the Pacific War. The island was returned to Japan in 1968 and is today visited by veterans and families for memorial services, jointly administered by the Japan Air Self-Defense Force and the United States Armed Forces.
