Iwo Jima, Volcano Islands · March 14, 1945

On this date in 1945 the U.S. flag was raised over the 10‑sq‑mile island of Iwo Jima in a for­mal flag-raising cere­mony. The battle for the bar­ren Japa­nese-held is­land lying some 760 miles south­east of Tokyo was the most bitterly con­tested of the war. Its cap­ture was a pre­lude to the battle for Oki­nawa, 340 miles closer to the Japa­nese Home Islands.

Japa­nese Army and Navy troops had bur­rowed deep into the vol­ca­nic rock, creating a de­fen­sive strong­hold of well-con­cealed tun­nels, bunkers, and machine-gun nests in­tended to inflict max­i­mum casual­ties on U.S. forces and delay their pro­gress toward their home­land. Each side in­flicted enor­mous car­nage on the other, partly because the bar­ren terrain offered little cover, and partly because the key wea­pons for clearing out the thou­sands of Japa­nese posi­tions were hand gre­nades, hand­held flame­throwers, and “Ron­son” or “Zip­po” tanks that shot flaming liquid on tar­gets almost 500 ft away.

Over 22,000 Japa­nese de­fenders died or com­mitted sui­cide during the 36‑day cam­paign, which began on Febru­ary 19 when landing craft un­loaded 30,000 men from the Third, Fourth, and Fifth Marine Divi­sions (the first of 70,000), along with am­phib­ious vehicles and equip­ment. Marines and sailors suffered over 6,700 killed out of some 26,500 casu­al­ties. Mt. Suri­bachi, the defining geo­graphical land­mark on the island and the site of the flag-raising made famous by Joe Rosen­thal’s iconic photo­graph, was captured on Febru­ary 23, but resis­tance con­tinued at the north end of the island for three more weeks.

Cap­turing Iwo Jima, which lay mid­way between the Mari­ana Is­lands and Japan, had been moti­vated by the desire to fly long-range P‑51 Mus­tang fighters from the island to escort B‑29 bombers from their Mari­ana bases in day­light raids on Japan. That proved un­neces­sary when U.S. Army Air Forces resorted to low-alti­tude (under 10,000 ft) night aerial attacks that met no signif­i­cant Japa­nese resis­tance. The is­land served as an emer­gency landing strip for Amer­i­can bombers for the rest of the war. Some 2,400 emer­gency stops were made over the next five months. Most of the landings were pre­cau­tionary, but if 10 per­cent of the crews were saved, that repre­sented about 2,600 airmen.

Japa­nese air­craft from Iwo Jima were able to bomb U.S. B‑29 bases in the Mari­anas, and radio opera­tors on Iwo Jima were able to send advance warning to the Japa­nese Home Islands every time B‑29s passed north over­head.

Japa­nese troops under their ingen­ious and cou­ra­geous com­mander, Gen. Tada­michi Kuri­ba­yashi, were respon­sible for the deaths of a third of all U.S. Marines killed during the en­tire four-year Pacific con­flict. Twenty-seven Medals of Honor were awarded to Marines and sailors, many post­humously, more than were awarded for any other single operation during the war.

These light but extremely accu­rate wea­pons did some of their best work in the south­ern part of the is­land. Over 35 days approx­i­mately 28,000 com­batants died, in­cluding 6,821 Amer­i­cans and nearly 22,000 Japa­nese by fighting or ritual sui­cide, making Iwo Jima one of the cost­liest battles of World War II. Only 216 Japa­nese defenders were cap­tured during the cataclysmic battle.

Right: Joe Rosenthal’s Pulitzer Prize-winning image depicts five Marines and one sailor raising the Stars and Stripes over Mt. Suri­bachi five days into the Battle of Iwo Jima. Three of the flag-raisers died at Bloody Gorge on the north side on the island, where the worst of the fighting took place. Three flag-raisers—Marine privates Rene Gagnon and Ira Hayes and Phar­macy Mate Second Class John Bradley—sur­vived the horrific com­bat and partici­pated in a war bonds tour in the States that featured reenactments of the flag raising.
