On the night of May 6, 1942, Lieutenant General Jonathan Wainwright sat in a concrete bunker on Corregidor Island and composed the hardest message of his life. Around him, some 11,000 American and Filipino soldiers waited in tunnels and bomb shelters. They had been under siege for seventy-three days. They were out of food, out of ammunition, and out of hope.

Above ground, Japanese artillery had turned the island into a moonscape. Every building was destroyed. Every gun position was obliterated. The defenders were eating mule meat and fighting with World War I rifles.

Medical supplies were gone. Water was running out. And five thousand Japanese assault troops had just come ashore. Wainwright knew what he had to do.

He picked up the radio and broadcast a message to the Japanese commander. Four words would haunt him for the rest of his life: “I surrender Corregidor unconditionally. ”

Corregidor sits at the mouth of Manila Bay, three miles long and shaped like a tadpole. The Americans called it “the Rock,” and for good reason.

Steep cliffs, dense jungle, and by 1941 the most heavily fortified position in the Pacific. America had spent forty years and millions of dollars turning Corregidor into an impregnable fortress. The island bristled with coastal defense guns, including massive twelve-inch weapons that could sink a battleship at fifteen miles, along with smaller batteries, anti-aircraft guns, mortars, and machine gun nests—more than sixty artillery pieces in total. But the real strength lay underground.

The Malinta Tunnel complex, a thousand feet of main tunnel carved through solid rock with dozens of lateral branches, held ammunition storage, a hospital with a thousand beds, headquarters offices, communication centers, and living quarters. The tunnel could house ten thousand men and withstand any bombardment. The plan had been simple. If Japan attacked, American forces in the Philippines would withdraw to the Bataan Peninsula and Corregidor, hold out for six months, and wait for the Navy to sail from Pearl Harbor and relieve them.

That was the plan. Reality played out very differently. On December 8, 1941, the same day as the attack on Pearl Harbor across the international date line, Japanese bombers struck American airfields in the Philippines. Within hours, most of the U.

S. Air Force in the islands was destroyed on the ground. Without air cover, the Philippines were defenseless. General Douglas MacArthur commanded all American and Filipino forces, 130,000 troops, but most were poorly trained Filipino reservists with outdated equipment.

When the Japanese invasion force landed on December 22, MacArthur’s defensive lines collapsed almost immediately. On December 24, he declared Manila an open city and withdrew to Bataan. Eighty thousand American and Filipino troops crammed into the jungle peninsula. Another ten thousand withdrew to Corregidor.

They thought they would hold for six months. But the Navy was not coming. Pearl Harbor had been devastated, and the Pacific Fleet could not sail to the Philippines even if it wanted to. MacArthur’s forces were on their own; they just did not know it yet.

January and February 1942 saw desperate fighting on Bataan. The defenders held against repeated Japanese attacks, but they were starving. Supply shipments could not get through the Japanese blockade. Rations were cut to half, then a quarter, then less.

Men were eating monkeys, snakes, anything they could find. On Corregidor, the garrison watched Bataan’s agony from across the water. They were better supplied and better protected, but they knew their turn was coming. On March 11, 1942, President Roosevelt ordered MacArthur to evacuate to Australia.

MacArthur did not want to go, but orders were orders. He left Corregidor by PT boat, leaving behind his famous promise: “I shall return. ” Command passed to Wainwright, a fifty-eight-year-old cavalry officer who had never expected to command the entire Philippine defense. Now he was responsible for ninety thousand men on Bataan and Corregidor with no hope of relief.

On April 9, 1942, Bataan fell. Seventy-six thousand starving, sick American and Filipino soldiers surrendered, the largest surrender in American military history. They would endure the Bataan Death March, and thousands would die. But eleven thousand men on Corregidor still held out.

And now every Japanese gun in the region turned on that tiny island. The day after Bataan surrendered, Japanese artillery batteries on the southern tip of the peninsula, just two miles across the water from Corregidor, opened fire. The bombardment started with a few shells testing range and finding targets. Then it became a deluge.

Hundreds of shells per hour rained down from heavy artillery and mortars. The Japanese were using every gun they had captured on Bataan—and they had captured a lot. The Americans called it “the pounding,” an unending barrage that shook the island day and night. Within days, most above-ground structures were destroyed.

Barracks collapsed. The parade ground became a crater field. But the real terror was what the bombardment did to the men. Constant explosions, no sleep, the ground shaking, dust choking the air.

Men went deaf from the concussions. Some went mad from the stress. The defenders could not fight back effectively. Their coastal guns were designed to hit ships, not land targets, and the barrels could not depress low enough to reach the Japanese batteries on Bataan.

A few guns could engage, but Japanese counterfire quickly knocked them out. For every shell the Americans fired, the Japanese fired twenty back. Wainwright moved his headquarters deeper into Malinta Tunnel. The tunnel became home to ten thousand people—soldiers, nurses, civilians who had fled Manila, even women and children.

The lateral tunnels were packed. Men slept in shifts because there was not room for everyone to lie down at once. The air was stale and hot. Temperatures inside reached one hundred degrees.

Above ground was death. Below ground was miserable but survivable, so the defenders stayed underground as much as possible. The artillery crews were the bravest. They manned their positions during the day and retreated to the tunnel at night.

Some did not make it back. By late April, food became the critical problem. Rations were cut first to three-quarters, then half, then a third. Men were getting fifteen hundred calories per day when they needed three thousand.

The mules and horses were slaughtered for food. Mule meat became a staple—tough, stringy, and terrible, but it was protein. When the mules ran out, men caught anything that moved: monkeys, iguanas, snakes. One soldier wrote in his diary about eating roasted rat and being grateful for it.

Vitamin deficiency diseases appeared. Beriberi swelled men’s legs and weakened their hearts. Scurvy made gums bleed and teeth loosen. Night blindness set in from lack of vitamin A.

The hospital in Malinta Tunnel was overwhelmed, not from combat casualties, though there were plenty, but from disease and malnutrition. Dysentery was epidemic. Men lost thirty, forty, fifty pounds and looked like skeletons. Medical supplies were running out.

Morphine was rationed. Antibiotics were gone. Bandages were washed and reused until they fell apart. Surgery was performed with minimal anesthesia because there was not enough to go around.

The nurses were heroes. Army and Navy nurses who had stayed on Corregidor when they could have evacuated worked eighteen-hour shifts in the tunnel hospital, held men’s hands as they died, changed dressings on infected wounds, and never gave up. Water became scarce, not because the island lacked it, but because the distribution system was destroyed. Wells and pumps were hit by artillery.

Men collected water from shell holes and rainwater when it rained. May arrived. Day fifty of the siege. The defenders were ghosts: hollow-eyed, emaciated, filthy, with uniforms in tatters.

Ammunition was critically low. The big coastal guns were down to a few shells each. If the Japanese attacked, the defenders could fight for perhaps a day before running dry. Morale was the worst casualty.

The men knew no help was coming. They listened to Japanese propaganda broadcasts promising good treatment if they surrendered. They did not believe it, but the alternative was dying on the island for nothing. Wainwright tried to keep spirits up, walking through the tunnel and promising that America had not forgotten them.

But he knew it was a lie. The Philippines had been written off. Some men talked about escape; a few tried, and none succeeded. Suicide increased among those who saw no hope.

On May 1, day sixty-seven, the Japanese bombardment intensified beyond anything the defenders had thought possible. The Japanese had brought in heavy siege artillery from Singapore: eight-inch guns and 240-millimeter howitzers. The new bombardment averaged five hundred shells per hour. In a single twenty-four-hour period, Corregidor took over ten thousand shells.

Men’s ears bled from the overpressure. Topside ceased to exist as anything recognizable. The gun batteries were systematically destroyed. By May 4, only three batteries were still operational, and they had almost no ammunition.

Japanese bombers joined the attack, flying unopposed because the anti-aircraft guns had nothing left to fire. One bomb hit near the hospital lateral in Malinta Tunnel, partially collapsing the entrance and trapping wounded men. Some suffocated before rescuers reached them. On May 5, day seventy, Wainwright called a meeting of his commanders.

The situation was hopeless. They had maybe forty-eight hours of food left, almost no ammunition, and no water reserves. The men were too weak to fight effectively even if they had weapons. The commanders agreed they could not hold much longer, but they also could not surrender without a fight.

That night, the Japanese bombardment reached its climax, with over sixteen thousand shells falling on Corregidor in twenty-four hours. Dawn on May 6 revealed a hellscape. Smoke and dust obscured everything. Fires burned across the island.

This was the end. At 10:30 that night, the bombardment suddenly stopped. The silence was eerie. Then the defenders heard boat engines.

The Japanese were coming. Two thousand troops of the Fourth Division loaded onto landing craft and headed for the eastern beaches of the island’s tail. The few remaining guns opened fire, but there were not enough defenders and almost no ammunition. The first wave took casualties, but more waves followed.

By midnight, two thousand Japanese troops were ashore. By 2:00 a. m. , another three thousand had landed.

The defenders, weak from starvation and armed with obsolete rifles, could not stop them. Japanese forces pushed toward Malinta Tunnel from the east while more troops landed on the north shore. A Japanese tank battalion came ashore. The defenders had no anti-tank weapons.

Inside the tunnel, panic spread. Ten thousand people, mostly non-combatants, were trapped underground with Japanese troops approaching. Wainwright faced an impossible choice: keep fighting and everyone in the tunnel dies, or surrender and hope some survive as prisoners of war. He knew what Japanese captivity meant.

He had heard the stories from China. Torture, execution, death marches. But at least some men would survive. If they kept fighting, none would.

At 4:00 a. m. on May 6, Japanese troops were five hundred yards from Malinta Tunnel. Fighting was hand-to-hand in places.

Wainwright made his decision. He ordered a white flag raised and broadcast a message to the Japanese commander, Lieutenant General Masaharu Homma, offering to surrender the forces on Corregidor. The Japanese response was immediate: they demanded unconditional surrender of all American forces in the Philippines, not just Corregidor but all remaining troops, including guerrilla forces scattered across dozens of islands. Wainwright could not agree to that; he did not command those forces.

But Homma threatened to resume the attack and kill everyone on Corregidor if he did not comply. Wainwright had no choice. He agreed and broadcast messages to all American commanders in the Philippines, ordering them to surrender. Some did.

Others refused and continued fighting as guerrillas. But officially, American resistance in the Philippines ended on May 6, 1942. The surrender of Corregidor was the largest American surrender since the Civil War. Eleven thousand five hundred American and Filipino troops laid down their arms.

Combined with the seventy-six thousand who surrendered on Bataan, nearly ninety thousand men went into Japanese captivity. What followed was a nightmare that made the siege look merciful by comparison. The prisoners were marched to Manila. Those who could not walk were bayoneted or shot.

Hundreds died on the march. In the prison camps—Bilibid, Cabanatuan—the men were overcrowded, filthy, and disease-ridden. Dysentery killed hundreds. Malaria was epidemic.

Food was worse than on Corregidor: a handful of rice per day. The average prisoner lost sixty pounds. Japanese guards were brutal, beating men for minor infractions and executing them at random. Some prisoners were shipped to Japan on “hell ships,” cargo vessels packed with men in the holds.

Many died from suffocation, disease, and thirst, and some ships were sunk by American submarines that did not know they carried prisoners. Of the 11,500 men who surrendered on Corregidor, approximately 40 percent died in captivity. Four thousand six hundred men survived the seventy-three-day siege only to die in prison camps over the next three years. Wainwright survived.

He was held in Manchuria as a high-value prisoner, forced to make propaganda broadcasts urging resistance forces to surrender. He endured three years of psychological torture, humiliation, and starvation. When Japan surrendered in August 1945, he was freed, weighing 140 pounds, down from 200. He was present on the USS Missouri when Japan signed the surrender documents.

MacArthur had invited him specifically. Wainwright wept during the ceremony. He returned to America expecting a court-martial for surrendering. Instead, he received the Medal of Honor.

President Truman personally awarded it, recognizing that Wainwright had made an impossible choice and saved thousands of lives. The defenders of Corregidor could not win. They could only delay the inevitable and hope for relief that never came. They were starving, out of ammunition, and out of water, facing five thousand Japanese assault troops with tanks while defending ten thousand non-combatants trapped in a tunnel.

They could have fought to the last man. Some wanted to. But Wainwright made the harder choice. He surrendered to save lives.

Thousands of men survived captivity who would have died in a final battle. Many more died as prisoners, but some lived. A last stand would have meant total annihilation. They held an impossible position for seventy-three days under conditions that would break most men.

They fought until they literally had nothing left to fight with. Their sacrifice was not in vain. They tied down Japanese forces and bought time for America to rebuild after Pearl Harbor. They showed the world that America would not quit, even when losing.

Today, Corregidor is a memorial. The ruins remain, preserved as they were after the bombardment. Malinta Tunnel is open for tours.

Visitors can see where eleven thousand men made their final stand, where America suffered one of its darkest defeats but also one of its finest hours of courage.
