Okinawa
Iwo became a base from which the Superforts could fly closer to the Japanese capital undetected and under protection of Iwo-based American fighter planes. Perhaps even more welcome to these gallant airmen, crippled B-29s unable to make the fifteen-hundred-mile flight back to Saipan could now touch down safely on tiny Iwo; or if shot down off the shores of Nippon, could even be reached by Iwo-based Dumbo rescue planes. Thus, not only could these exorbitantly expensive aerial elephants be saved, but their truly more valuable crews as well. On the night of March 9, to prove their worth and sound the requiem of the “unconquerable” island empire, the Superforts already striking Tokyo, Nagoya, Osaka, and Kobe in pulverizing three-hundred-plane raids came down to six thousand feet over Tokyo to loose the dreadful firebombs that consumed a quarter of a million houses and made a million human beings homeless while killing 83,800 people in the most lethal air raid in history—even exceeding the death and destruction of the atomic-bomb strikes on Hiroshima and Nagasaki that were to follow.
Meanwhile the huge Japanese merchant fleet, employed in carrying vital oil and valuable minerals to the headquarters of an empire singularly devoid of natural resources, had been steadily blasted into extinction by the flashing torpedoes of the United States Navy’s submarines. Here indeed were the unsung heroes of the splendid Pacific sea charge of three years’ duration: four thousand miles from Pearl Harbor to the reef-rimmed slender long island of Okinawa. These men of “the silent service,” as it was called, were fond of joking about how they had divided the Pacific between the enemy and themselves, conferring on Japan “the bottom half.” In fact it was true. Only an occasional supply ship or transport arrived at or departed Nippon’s numerous sea-ports, themselves silent, ghostly shambles. Incredibly, the American submarines, now out of sea targets, had penetrated Japan’s inland seas to begin the systematic destruction of its ferry traffic. Transportation on the four Home Islands of Honshu, Shikoku, Kyushu, and Hokkaido was at a standstill. Little was moved: by road or rail, over the water or through the air. In the Imperial Palace hissing, bowing members of the household staff kept from Emperor Hirohito the shocking, grisly protests arriving in the daily mail: the index fingers of Japanese fathers who had lost too many sons to “the red-haired barbarians.” Most of these doubters—silent and anonymous because they feared a visit from the War Lords’ dreaded Thought Police—were men who had lived and worked in America, knowing it for the unrivaled industrial giant that it was. They did not share the general jubilation when “the emperor’s glorious young eagles” arrived home from Pearl Harbor. Their hearts were filled with trepidation, with secret dread for the retribution that they knew would overtake their beloved country.
For eight months following Pearl Harbor, the victory fever had raged unchecked in Japan. During that time the striking power of America’s Pacific Fleet had rolled with the tide on the floor of Battleship Row. Wake had fallen, Guam, the Philippines. The Rising Sun flew above the Dutch East Indies, it surmounted the French tricolor in Indochina, blotting out the Union Jack in Singapore, where columns of short tan men in mushroom helmets double-timed through silent streets. Burma and Malaya were also Japanese. India’s hundreds of millions were imperiled, great China was all but isolated from the world, Australia looked fearfully north to Japanese bases on New Guinea, toward the long double chain of the Solomon Islands drawn like two knives across its lifeline to America. But then, on August 7, 1942—exactly eight months after Vice Admiral Chuichi Nagomo had turned his aircraft carriers into the wind off Pearl Harbor—the American Marines landed on Guadalcanal and the counter-offensive had begun.
In Japan the war dance turned gradually into a dirge while doleful drums beat a requiem of retreat and defeat. Smiling Japanese mothers no longer strolled along the streets of Japanese towns and cities, grasping their “belts of a thousand stitches,” entreating passersby to sew a stitch into these magical charms to be worn into battle by their soldier sons. For now those youths lay buried on faraway islands where admirals and generals—like the Melanesian or Micronesian natives whom they despised—es—caped starvation by cultivating their own vegetable gardens of yams and sweet potatoes. And the belts that had failed to preserve the lives of the boys who wore them became battle souvenirs second only to the Samurai sabers of their fallen officers.
This, then, was the Japan that the United States Joint Chiefs of Staff still considered a formidable foe, so much so that it could be subdued only by an invasion force of a million men and thousands of ships, airplanes, and tanks. To achieve final victory, Okinawa was to be seized as a forward base for this enormous invading armada. In the fall of 1945 a three-pronged amphibious assault called Operation Olympic was to be mounted against southern Kyushu by the Sixth U.S. Army consisting of ten infantry divisions and three spearheading Marine divisions. This was to be followed in the spring of 1946 by Operation Coronet, a massive seaborne assault on the Tokyo Plain by the Eighth and Tenth Armies, spearheaded by another amphibious force of three Marine divisions and with the First Army transshipped from Europe to form a ten-division reserve. The entire operation would be under the command of General of the Armies MacArthur and Fleet Admiral Chester Nimitz.
Okinawa would be the catapult from which this mightiest amphibious assault force ever assembled would be hurled.
The Divine Wind
CHAPTER THREE
Japanese Imperial Headquarters, still refusing to believe that Nippon was beaten, still writing reports while wearing rose-colored glasses, also anticipated an inevitable and bloody fight for Okinawa as the prelude to a titanic struggle for Japan itself. While the American Joint Chiefs regarded Operation Iceberg as one more stepping-stone toward Japan, their enemy saw it as the anvil on which the hammer blows of a still-invincible Japan would destroy the American fleet.
Destruction of American sea power remained the chief objective of Japanese military policy. Sea power had brought the Americans through the island barriers that Imperial Headquarters had thought to be impenetrable, had landed them at Iwo within the very Prefecture of Tokyo, and now threatened to provide them a lodgment 385 miles closer to the Home Islands. Only sea power could make possible the invasion of Japan, something that had not happened in three thousand years of Japan’s recorded history—something that had been attempted only twice before.
In 1274 and 1281 Kublai Khan, grandson of the great Genghis Khan and Mongol emperor of China, massed huge invasion fleets on the Chinese coast for that purpose. Japan was unprepared to repel such stupendous armadas, but a kamikaze, or “Divine Wind”—actually a typhoon—struck both Mongol fleets, scattering and sinking them.
In early 1945, nearly seven centuries later, an entire host of Divine Winds came howling out of Nippon. They were the suicide bombers of the Special Attack Forces, the new kamikaze who had been so named because it was seriously believed that they too would destroy another invasion fleet.
They were the conception of Vice Admiral Takejiro Onishi. He had led a carrier group during the Battle of the Philippine Sea. After that Japanese aerial disaster known to the Americans as “the Marianas Turkey Shoot,” Onishi had gone to Fleet Admiral Soemu Toyoda, commander of Japan’s Combined Fleet, with the proposal to organize a group of flyers who would crash-dive loaded bombers onto the decks of American warships. Toyoda agreed. Like most Japanese he found the concept of suicide—so popular in Japan as a means of atonement for failure of any kind—a glorious method of defending the homeland. So Toyoda sent Onishi to the Philippines, where he began organizing kamikaze on a local and volunteer basis. Then came the American seizure of the Palaus and the Filipino invasion.
On October 15, 1944, Rear Admiral Masafumi Arima—the first kamikaze—tried to crash-dive the American carrier Franklin. He was shot down by Navy fighters, but Japanese Imperial Headquarters told the nation that he had succeeded in hitting the carrier—which he had not done—and thus “lit the fuse of the ardent wishes of his men.”
The first organized attacks of the kamikaze came on Oct
ober 25, at the beginning of the Battle of Leyte Gulf. Suicide bombers struck blows strong enough to startle the Americans and make them aware of a new weapon in the field against them, but not savage enough to shatter them. Too many kamikaze missed their targets and crashed harmlessly into the ocean, too many lost their way either arriving or returning, and too many were shot down. Of 650 suiciders sent to the Philippines, only about a quarter of them scored hits—and almost exclusively on small ships without the firepower to defend themselves like the cruisers, battleships, and aircraft carriers. But Imperial Headquarters, still keeping the national mind carefully empty of news of failure, announced hits of almost 100 percent. Imperial Headquarters did not believe its own propaganda, of course. Its generals and admirals privately guessed hits ranging from 12 to 50 percent, but they also assumed that nothing but battleships and carriers had been hit.
Thus was the kamikaze born, in an outburst of national ecstasy and anticipated deliverance. In the homeland a huge corps of suiciders was organized under Vice Admiral Matome Ugaki. By January 1945 they were part of Japanese military strategy, if not the dominant part. So many suiciders would be ordered out on an operation, to be joined by so many first-class fighters and bombers: the fighters to clear the skies of enemy interceptors, the bombers to ravage American shipping and guide the kamikaze to their victims.
They needed to be guided because they usually were a combination of old, stripped-down aircraft and young, often hopped-up flyers. Admiral Ugaki did not use his newest planes or his most skilled pilots, as Admiral Onishi had in the Philippines. Ugaki considered this wasteful. He believed that the “spiritual power” of the “glorious, incomparable young eagles” would compensate for the missing firepower of obsolete crates from which even the instruments had been removed. At a period in the Pacific War when perceptive Japanese commanders were beginning to ridicule the “bamboo-spear tactics” of the School of Spiritual Power, as opposed to the realities of firepower, Ugaki was showering his brave young volunteers—for brave they truly were—with encomiums of praise intended to silence whatever reservations they may have had about piloting these patched-up old cripples, and also to inspire the nation.
So the suiciders were hailed as saviors: wined, dined, photographed, lionized. Many of them attended their own funerals before taking off on their last mission. Farewell feasts were held in their honor at the numerous airfields on the southernmost Japanese island of Kyushu. Solemn Samurai ceremonies were conducted, and many toasts of sake drunk, so that some of the pilots climbed aboard their airplanes on wobbly legs. It did not seem to occur to the Japanese—and especially Ugaki—that insobriety might affect the aim of the kamikaze and thus defeat the purpose of the suicide corps; and this was because the concept of the suicide-savior had so captivated the nation from schoolgirls to Emperor Hirohito himself that the slightest word of criticism would have been regarded as treason. And it was this very deep and very real faith in another coming of a Divine Wind that dictated to the planners at Imperial Headquarters exactly how the battle of Okinawa was to be fought.
The speed with which the Americans were overrunning the Philippines had produced a mood of the blackest pessimism at Imperial Headquarters in Tokyo in late 1944—until those roseate reports of kamikaze success during December and January replaced the darkest despair with the brightest hopes. By 1945 Headquarters had decided that the United States would next strike at Okinawa to seize a base for the invasion of Japan proper, as the four Home Islands were called. It was now believed that the kamikaze corps could greatly improve the chances for a successful defense of Okinawa, and thus perhaps—even probably—prevent enemy landings in the Home Islands. So a plan called Ten-Go, or “Heavenly Operation,” was devised. New armies were to be formed from a reserve of military-age men who had been deferred for essential labor, while a powerful air force built around the kamikaze would be organized to destroy the Americans.
More than four thousand airplanes, both suicide and conventional, would launch an all-out attack, joined by hundreds of suicide motorboats operating from Okinawa and the Kerama Islands and followed by a suicide dash of Japan’s remaining warships, including the mighty battleship Yamato. The air assaults would come from two directions: north from Formosa where the Japanese Army’s Eighth Air Division and the Navy’s First Air Fleet were based, and south from Kyushu, with a more powerful force combining several Army and Navy commands, all under the direction of Vice Admiral Ugaki. On February 6 a joint Army-Navy Air Agreement stated:In general Japanese air strength will be conserved until an enemy landing is underway or within the defense sphere ... Primary emphasis will be laid on the speedy activation, training and mass employment of the Special Attack Forces (kamikaze) ... The main target of Army aircraft will be enemy transports, and of Navy aircraft carrier attack forces.
On its face this was a bold plan conceived in an atmosphere of the most cordial cooperation. Actually, the only leaders motivated by the same conviction were those who believed that the war could no longer be won. Otherwise, there was a deep divergence: the Navy officers seeing Ten-Go as the last opportunity to score a great, redeeming victory; the Army staffers in agreement that the final battle would be fought not on Okinawa but on Kyushu. Though their views conflicted, their reasoning was logical: the sailors, certain that if airpower could not stop the enemy at Okinawa, neither would it do so on Kyushu; the Army insisting that even on the Philippines the Americans had not yet fought a major Japanese army, and that, shattered and whittled by the suicide-saviors, they could be repulsed in Japan proper. However, all—even the doubters—were convinced that at the very least a severe defeat must be inflicted on the Americans to compel the Allies to modify their demand for Unconditional Surrender.
There was one more consideration, probably more apparent to the Army than the Navy. Bamboo-spear tactics were out. The illogical belief that spiritual power could conquer firepower had spawned that other cause of Japan’s absolute inability to halt the American charge across the Pacific: the doctrine of destroying the enemy invaders “at the water’s edge.” Those nocturnal, massed frontal attacks known as “Banzai charges” had repeatedly been broken in blood, leaving the Japanese defenders so weakened that they were powerless to resist. Now there was a new spirit informing the Japanese Army: defense in depth—as careful as the Banzai was reckless, as difficult for the enemy to overcome as the foolhardy wild Banzai had been easy for him to shatter, and so costly in the attrition of enemy men, machines, and ships as to weary the Americans and thus induce them to negotiate.
Ambush, or the tactics of delay raised to a military science, began on the large island of Biak off the western extremity of New Guinea. It was conceived by Colonel Kuzume Naoyuki, commander of about eleven thousand troops of the defense garrison there. Disdainful of the doctrine of destruction at the water’s edge, he decided instead to allow the Americans to come ashore unopposed so that they would stroll unwarily into the trap he would prepare for them. This would turn the area around the vital airfield there into a martial honeycomb of caves and pillboxes—all mutually supportive—filled with riflemen, automatic weapons, artillery, batteries of mortars, and light tanks. Naoyuki also stockpiled these positions with enough ammunition, food, and water—that priceless liquid was less than abundant on Biak, where the heat and humidity would take a toll equal to enemy gunfire—to sustain his defense for months. Thus, when the 162nd Infantry of the Forty-first Division of the U.S. Army landed on Biak on May 27, 1944, they did indeed move confidently inland expecting little opposition—until they reached that vital airfield. Then, from the low-lying terrain around them and the ridges above, there fell a terrible storm of shot and shell that pinned them to the ground; it was not until dark that amtracks were able to extricate them from the trap.
Thereafter, there was no foolish and furious Banzai by which the Japanese enemy customarily bled itself to death. Biak was a grinding, shot-for-shot battle. Ambush, or delay, was repeated at Peleliu and Iwo Jima, battles that the U.S. Mar
ines expected to be won within days or a week or so but lasted for months, with staggering losses not only in valuable time but in still more valuable life and equipment.
These were the tactics that Lieutenant General Mitsuru Ushijima intended to employ on Okinawa with his defending Japanese Thirty-second Army. After his arrival there in August 1944, he hurled himself into the gratifying task of turning that slender long island into an ocean fortress. In January 1945, he sent his chief of staff, Lieutenant General Isamu Cho, to Tokyo for a review of his defenses. Imperial Headquarters planners were delighted with his preparations, for they dovetailed with Ten-Go. Ushijima’s monster ambush was just the tactic to lure the Americans within range of the suiciders—airborne and seaborne—to be smashed so shatteringly that the Thirty-second Army could take the offensive and destroy them.
Upon his return to Okinawa, Isamu Cho was a happy soldier, thirsting for battle and bursting to tell his chief the good news about Japan’s devastating new weapon of the Divine Wind.
The Japanese Samurai
CHAPTER FOUR
To understand the Samurai—a hereditary class of professional warriors peculiar to Japan—it is necessary to understand the history of Nippon. Up until 1853, when the American Commodore Matthew Perry opened Japan to world trade, Nippon had been a hermit kingdom into which no foreigner who valued his life would venture. True, between the founding of the Island Empire in 660 B.C. and the arrival of Perry, there had been a brief interlude of intercourse with the West. This occurred after a storm drove a China-bound Portuguese ship ashore in 1543. Later ships brought Catholic missionaries, among them Saint Francis Xavier, the great Jesuit missionary and a leader of the Catholic Counter-Reformation, who stepped ashore in 1549. Under his influence the population of a large area of the southern island of Kyushu became Catholic Christians. This pleased neither the ruling shoguns (military commanders in chief who had seized power from the emperor) or the Buddhist priests.
