The Battle of Iwo Jima: “Uncommon Valor Was a Common Virtue”

On a cold, wind-swept volcanic island in the Pacific, U.S. Marines and sailors fought one of the most grueling battles in American military history. The Battle of Iwo Jima, lasting 36 days from February 19 to March 26, 1945, became a defining moment in the Pacific War. It was a battle of ash, fire, and relentless attrition—where every yard of ground was paid for in blood. Yet amid the devastation, one image rose above the chaos: Joe Rosenthal’s photograph of Marines raising the American flag atop Mount Suribachi. That image came to symbolize not only victory, but the determination, sacrifice, and shared courage of the men who fought there. As Admiral Chester W. Nimitz later said, “Among the Americans who served on Iwo Jima, uncommon valor was a common virtue.”

Why Iwo Jima Mattered

Iwo Jima was a tiny volcanic island, just eight square miles in size, but its strategic importance was enormous. Located roughly halfway between the Mariana Islands and Japan, it sat near the air route used by American bombers striking the Japanese home islands. The island also contained warning stations and fighter airfields that could help Japan detect incoming raids and scramble defenses.

For U.S. planners, capturing Iwo Jima offered several advantages. First, it could serve as an emergency landing base for damaged B-29 bombers returning from missions over Japan. Second, it could provide a base for American fighter escorts and reconnaissance aircraft. Third, it would remove a forward Japanese observation post that had been used to track U.S. air operations.

The island was not expected to be easy to take, but many American commanders believed the cost would be justified by the payoff. They were right about the importance of the island—but the battle would prove far more costly than anticipated.

The Island of Ash and Fire

Iwo Jima was unlike the tropical battlefields many Americans imagined when they thought of the Pacific. It was bleak, black, and unnerving. The island was formed from volcanic rock and ash, with soft, sulfurous soil that made digging foxholes and tunnels difficult. Beneath the surface, however, Japanese engineers had spent months creating one of the most formidable defensive systems of the war.

The Japanese commander, Lieutenant General Tadamichi Kuribayashi, understood that he could not stop the American invasion on the beaches. Instead, he built a defense in depth. His troops constructed miles of tunnels, bunkers, caves, gun emplacements, and hidden artillery positions. They were ordered to conserve ammunition and avoid the kind of suicidal banzai charges that had cost Japan so dearly elsewhere. Kuribayashi’s strategy was to inflict maximum casualties and delay the Americans as long as possible.

When U.S. Marines landed on February 19, 1945, they encountered a nightmare. At first, the beaches seemed strangely quiet. Then the Japanese opened fire from concealed positions inland and on the heights overlooking the landing zones. Tanks bogged down in volcanic sand. Men struggled to move equipment. Machine guns, mortars, and artillery raked the beachhead. What had begun as an assault quickly turned into a brutal test of endurance.

A 36-Day Struggle for Every Inch

The battle for Iwo Jima was not a swift assault but a grinding campaign of close combat, flamethrowers, grenades, demolition charges, and hand-to-hand fighting. The Marines had to seize a series of heavily fortified ridges, ravines, and high ground positions one by one. Japanese defenders, hidden in caves and tunnels, often appeared to vanish only to reemerge elsewhere. Even when positions were taken, they were often retaken by fire from another angle.

Mount Suribachi, the island’s southern peak, became one of the first major objectives. After days of combat, Marines reached the summit on February 23. It was there that they raised the American flag, an act that was both tactical and symbolic. From the top of the mountain, the flag could be seen across the island and from ships offshore. The moment lifted morale for the men still fighting below and signaled that progress, though costly, was being made.

But the battle was far from over. The northern half of the island was even more heavily fortified in places, and the fighting continued for weeks. American forces had to clear terrain such as the Motoyama Plateau and the “Meat Grinder,” where Japanese defenses exacted a terrible toll. The fighting became a war of attrition in the most literal sense. Every cave had to be sealed, every bunker destroyed, every ridge taken under fire.

By the time organized resistance ended on March 26, the Marines had suffered staggering casualties. More than 6,800 Americans were killed, and nearly 20,000 were wounded. Japanese losses were even more devastating, with almost all of the island’s defenders killed. Iwo Jima was one of the bloodiest battles in Marine Corps history.

Joe Rosenthal’s Photograph and the Power of an Image

The flag-raising on Mount Suribachi might have been remembered as a proud but local moment in a long and costly campaign if not for Joe Rosenthal, an Associated Press photographer who happened to capture it on film. Rosenthal’s photograph showed six Marines raising the second, larger American flag on the summit. The image was not posed in the theatrical sense, but it did capture a real and spontaneous moment of teamwork and resolve.

The photograph spread quickly and electrified the American public. In a nation weary from years of war, it offered a powerful visual of unity and sacrifice. Unlike battlefield images that showed destruction and death, Rosenthal’s photo communicated motion, purpose, and shared effort. The men in the picture were anonymous at
