Japanese Banzai on Okinawa

On April 29, Emperor Hirohito’s birthday and the most important holiday in Japan, Lieutenant General Mitsuru Ushijima summoned his top commanders to his headquarters in a tunnel underneath Shuri Castle. For days they had been privately arguing over Isamu Cho’s proposal for a massive counter-stroke against the Americans. Now Ushijima wished them to discuss whether or not his strategy for defending Okinawa should be changed. Some historians say Ushijima was not present, others insist that he was. It does not seem likely, however, that the Thirty-second Army commander—even though it was not his custom to attend staff discussions—would ignore such a momentous meeting called by himself.

Ushijima’s chiefs sat on canvas camp chairs at a rough flat table covered with maps. Around them the stones of the tunnel glistened with sweat. Water from the moat surrounding medieval Shuri seeped through crevices in the wall or dripped incessantly on the floor of beaten earth. Dim light glinted weakly off the glasses worn by most of the officers in attendance or winked on the stars of the numerous generals present.

Isamu Cho sat close to Ushijima, staring arrogantly into the questioning gaze of his arch rival, Colonel Hiromichi Yahara. Just as he had predicted the debacle of General Cho’s abortive counter-attack of April 12-13, the rigidly rational Yahara was now prepared to oppose what he knew would be a plan for an even greater and more disastrous counter-stroke. By his patrician bearing he made it clear that he could not be bullied by either the rank or the fiery rhetoric of the burly general now rising to address the meeting.

Cho began with an incredible untruth: that the Japanese soldier—in the main from four to six inches shorter than his American enemies and from thirty to fifty pounds lighter—was a superb hand-to-hand fighter who could easily overpower the soft, effete American devils. A general clearing of throats and grunts of approval followed this absurd remark, either born of the School of the Rosy Report or emanating from the sake bottles being passed freely around. Very quickly most of the commanders present supported Cho’s plan: Lieutenant General Takeo Fujioka, commander of the Sixty-second Division, and also the plan’s coauthor; Lieutenant General Tatsumi Amamiya, swallowing his detestation of the boastful Fujioka in his eagerness to lead his untested Twenty-fourth Division into battle at last; and Major General Kosuke Wada, chief of the Fifth Artillery Command. Wada agreed with the others that the Thirty-second Army had made an achievement unprecedented in Pacific warfare: it had preserved its main body intact after a month of fighting.

This, Yahara bluntly interjected, happened only because the Americans had not yet hurled their full strength against the Naha-Shuri-Yonabaru line. But now that the outer defenses had fallen, because of the April 12-13 fiasco, the American commander was strengthening his assault forces, according to intelligence reports. An even bigger disaster would ensue if Cho’s massive counter-offensive were approved, he warned. And to speak of the valor of the troops was foolish, because even now, since there had been no issue of sweet-potato brandy on the emperor’s birthday, the men were discontented. For thirty days these gallant men had risen every morning to look down upon a Hagushi Anchorage still choked with enemy ships. The Divine Winds had not blown them away. It was difficult for even Japanese soldiers to believe that the Navy would come to their rescue—nor could they be blamed for complaining about being asked to fight alone one day’s sail from the homeland.

It was true, Isamu Cho replied slowly, that the Americans had not thrown in all their strength. But they were doing so now. There was a new Marine division in the enemy’s assault line, the First, the hated butchers of Guadalcanal. Another—the Sixth—was due to join them. This was the moment to destroy the Americans’ fresh power. But, Cho continued, the Thirty-second Army had also been reinforced. Had not our chief General Ushijima in his wisdom concluded that the enemy was not interested in storming the Minatoga Beaches, and so had ordered our comrades of the Twenty-fourth Division and Forty-fourth Brigade to join us here? Now it is we who are at full strength. Let us strike the enemy immediately and annihilate them before they can grind down to our main line.

Careful, full-scale counter-attack, not the foolish glory of the Banzai, would crush the Americans. There must be help from the kamikaze, then massed artillery fire with the troops attacking all along the line. The fresh Twenty-fourth Division would be hurled at the center and open a hole through which the Forty-fourth Brigade would pour in a thrust to the west coast. The Forty-fourth would then wheel south and the First Marine Division would be isolated and annihilated. The American Twenty-fourth Corps would be rolled up. There should also be counter-landings on both flanks. The Twenty-sixth Shipping Engineer Regiment would embark from Naha in barges, small boats, and native canoes to strike the rear of the Marine division. Later, the youths of the Twenty-sixth, Twenty-eighth, and Twenty-ninth Sea Raiding Squadrons would cross the reef and wade ashore to help the engineers. A similar counter-landing would strike the rear of the Seventh Infantry Division on the east.

It would be difficult to conceive a more complicated plan of attack, and Cho’s proposal calling for so many disconnected and disparate sallies—a montage of uncoordinated sorties if ever there was one—paid absolutely no heed to what the enemy’s reaction might be. Moreover, it was made doubly difficult by the Japanese unfailing reliance on a night attack to cancel out the American superiority in artillery, even if this meant confusing their own troops. Yet, when Colonel Yahara arose to criticize the operation, he praised it as tactically excellent, probably because he was about to demolish it as a strategic monstrosity and did not want to alienate Cho entirely. Yahara said:

“To take the offensive with inferior forces against absolutely superior enemy forces is reckless and will only lead to certain defeat. We must continue the current operation, calmly recognizing its final destiny—for annihilation is inevitable no matter what is done—and maintain to the bitter end the principle of a strategic holding action. If we should fail, the period of maintaining a strategic holding action, as well as the holding action for the decisive battle for the homeland, will be shortened. Moreover, our forces will inflict but small losses on the enemy, while on the other hand, scores of thousands of our troops will have been sacrificed in vain as victims of the offensive.”

Yahara sat down.

It was now up to Ushijima.

He nodded to Cho.

The attack would begin at dawn on May 4. Before that, the flank counter-landings would be launched. Before them the artillery would commence, and before everything would come the kamikaze.

The Japanese aerial assaults began at six o’clock on the night of May 3. Once again, the bombers sought to get at the rich pickings in the Hagushi Anchorage, but thirty-six of them were shot down and the rest forced to unload at high altitude, with little damage. Only the suicide-diving kamikaze broke through. They sank destroyer Little and an LSM, while damaging two mine layers and an LCS. After midnight, sixty bombers struck Tenth Army rear areas, coming in scattering window. Terrible antiaircraft fire rose in crisscrossing streams of light, as though a million narrow-beamed searchlights were aimed into the night, and the bombers dropped their loads aimlessly—though some of them landed in a Marine evacuation hospital.

An hour later Marine amtanks guarding Machinato Airfield on the west coast fired at voices on the beach. American cruisers, destroyers, and gunboats on “flycatcher” patrol shot at squat Japanese barges sliding darkly upcoast from Naha. The barges lost their way. Instead of landing far enough north to take the Marines in their rear, they veered inshore and blundered into the outposts of B Company, First Marines.

The Japanese sent up a screeching and gobbling of battle cries and the surprised Marines sprang to their guns. All up and down the sea wall the battle raged, with Marine amtracks moving out to sea and coming in again to grind the Japs to pieces between two fires. Some five hundred Japanese died in this futile west-flank landing.

The east-flank landings came to the same annihilating end. Navy patrol boats sighted the Japanese craft. They fired at them and turned night into day with star-shells. Soldiers of the Seventh Division’s Reconnaissance Troops joined the sailors to complete the destruction of four hundred men.

At dawn, the main attack began.

It went straight to the doom that Colonel Yahara had predicted. Wave after wave of the Twenty-fourth Division’s men shuffled forward to death in that gray dawn, moving among their own artillery shells, taking this risk in hopes of getting in on the Americans. But the soldiers of the Seventh and Seventy-seventh Divisions held firm—while American warships, sixteen battalions of division artillery, and twelve battalions of heavier corps artillery, plus 134 airplanes, smothered the enemy in a wrathful blanket of steel and explosive. Ships as big as the fourteen-inch-gunned New York and Colorado, as small as gunboats with 20 mm cannons, ranged up and down the east coast firing at the Japanese on call.

Across the island, the kamikaze dove again on ships in the Hagushi Anchorage, again falling on the luckless small vessels of the radar picket screen. With them were the baka bombs. This May 4 one of the baka hit the light mine-layer Shea and set it temporarily on fire. The kamikaze also sank two more destroyers, Luce and Morrison, as well as two LSMs, while damaging the carrier Sangamon, the cruiser Birmingham, another pair of destroyers, a minesweeper, and an LCS. Again, they failed to get at the cargo and transport ships. And they lost 95 planes.

Ashore, Isamu Cho’s massive counterthrust was being broken by that material power for which Mitsuru Ushijima had shown such profound respect. Much of the Japanese assault died aborning. Sometimes the Japanese closed, but rarely. There were seesaw battles up and down some of the ridges held by the Seventy-seventh, but they ended with the GIs either in command of their previous position or holding new ground farther inside the Japanese territory. One battalion of the Japanese Twenty-fourth Division got behind the Seventy-seventh on the left, but it was annihilated by a reserve battalion of the Seventh Division in a three-day fight. Otherwise the Twenty-fourth Division never punched that hole through which the Forty-fourth Brigade was to race and isolate the First Marine Division.

And the First began attacking on the morning of May 4. Even as the GIs on their left bore the brunt of Cho’s big sally, these Marines were battling southeast toward the key bastion of Shuri. They scored gains of up to four hundred yards. The next day they attacked again, once more pushing the Japanese back—even though their advance was made more costly by the fact that they were up against rested battalions of the Japanese Sixty-second Division. By the night of May 5 the Marines had picked up another three hundred yards. By that time Lieutenant General Isamu Cho’s massive stroke had been completely shattered. Those two days of fighting had cost the Japanese 6,227 dead. The Seventh and Seventy-seventh Divisions had lost 714 men killed or wounded while holding the line, the First Marine Division had taken losses of 649 men in the more costly business of attack. The next day the First gained another three hundred yards, and added a fourth Medal of Honor winner to its rolls since coming into the line on May 1. That day Corporal John Fardy smothered a grenade with his life, as had Pfc. William Foster. Sergeant Elbert Kinser did it on May 4. Two days before that, Corpsman Robert Bush had risked his life to give plasma to a wounded officer, driving off a Japanese rush with pistol and carbine, killing six of the enemy and refusing evacuation though badly wounded.

There would be more Medals of Honor won in the days to come. The First Division by May 5 had come against Ushijima’s main line, as had the GIs on their left. In front of the First was the western half of the Shuri bastion. To their right was Naha, and this would be assigned to the Sixth Marine Division the next day. In the sector of both these Marine divisions were systems of interlocking fortified ridges such as those encountered on Iwo Jima. Nor would the way be made easy here by further counter-attack.

A change had taken place at Shuri Castle. In tears, Lieutenant General Ushijima had promised Colonel Yahara that from now on he would listen to no one but him. The Ushijima-Cho relationship had ended in the recrimination of a red and useless defeat. Isamu Cho argued no longer. He became silent and stoical, convinced now that only time stood between the Thirty-second Army and ultimate destruction.
