Why did they use the atombomb?
(An Invasion Not Found in History Books)
Deep in the recesses of the National Archives in Washington, D.C., hidden for nearly four decades, lie thousands of pages of yellowing and dusty documents stamped "Top Secret." These documents, now declA**ified, are the plans for Operation Downfall, the invasion of Japan during World War II.
Only a few Americans in 1945 were aware of the elaborate plans that had been prepared for the Allied invasion of the Japanese home islands. Even fewer today are aware of the defences the Japanese had prepared to counter the invasion had it been launched.
Operation Downfall was finalised during the spring and summer of 1945.
It called for two mA**ive military undertakings to be carried out in succession and aimed at the heart of the Japanese Empire.
In the first invasion, - code-named Operation Olympic - American combat troops would land on Japan by amphibious A**ault during the early morning hours of 1 Nov. 1945 - 52 years ago. Fourteen combat divisions of soldiers and Marines would land on heavily fortified and defended Kyushu, the southernmost of the Japanese home islands after an unprecedented naval and aerial bombardment.
The second invasion 1 March 1946 - Code-named Operation Coronet - would send at least 22 combat divisions against 1 million Japanese defenders on the main island of Honshu and the Tokyo Plain. Its goal: the unconditional surrender of Japan. With the exception of a part of the British Pacific Fleet, Operation Downfall was to be a strictly American operation. It called for using the entire Marine Corps, the entire Pacific Navy, and elements of the 8th Army Air Force, the 8th Air Force (recently deployed from Europe), the 20th Air Force and the American Far Eastern Air Force. More than 1.5 million combat soldiers, with 3 million more in support -- more than 40 percent of all servicemen still in uniform in 1945 -- would be directly involved in the two amphibious A**aults.
Casualties were expected to be extremely heavy.
Admiral William Leahy estimated that there would be more than 250,000 Americans killed or wounded on Kyushu alone. Gen. Charles Willoughby, chief of intelligence for Gen. Douglas MacArthur, the Supreme Commander of the Southwest Pacific, estimated American casualties from the entire operation would be 1 million men by the fall of 1946. Willoughby's own intelligence staff considered this to be a conservative estimate.
During the summer of 1945, America had little time to prepare for such an endeavour, but top military leaders were in almost unanimous agreement that an invasion was necessary.
While a naval blockade and strategic bombing of Japan was considered to be useful, MacArthur, for instance, did not believe a blockade would bring about an unconditional surrender. The advocates for invasion agreed that while a naval blockade chokes, it does not kill; and though strategic bombing might destroy cities, it leaves whole armies intact.
So on 25 May 1945, the Joint Chiefs of Staff, after extensive deliberation, issued to MacArthur, Admiral Chester Nimitz and Army Air Force Gen. Henry "Hap" Arnold, the top secret directive to proceed with the invasion of Kyushu.
The target date was set for after the typhoon season.
President Truman approved the plane for invasions 24 July. Two days later, the United Nations issued the Potsdam Proclamation, which called upon Japan to surrender unconditionally or face total destruction. Three days later, the Japanese governmental news agency broadcast to the world that Japan would ignore the proclamation and would refuse to surrender.
During this same period it was learned -- via monitoring Japanese radio broadcasts -- that Japan had closed all schools and mobilised its school children, was arming its civilian population and was fortifying caves and building underground facilities.
Operation Olympic called for a four-pronged A**ault on Kyushu. Its purpose was to seize and control the southern one-third of that island and establish naval and air bases, to tighten the naval blockade of the home islands, to destroy units of the main Japanese army and to support the later invasion of the Tokyo Plain.
The preliminary invasion would begin 27 Oct. when the 40th Infantry Division would land on a series of small islands west and Southwest of Kyushu. At the same time, the 158th Regimental Combat Team would invade and occupy a small island 28 miles south of Kyushu.
On these islands, seaplane bases would be established and radar would be set up to provide advance air warning for the invasion fleet, to serve as fighter direction centres for the carrier-based aircraft and to provide an emergency anchorage for the invasion fleet should things not go well on the day of the invasion.
As the invasion grew imminent the mA**ive power of the Navy -- the Third and Fifth Fleets -- would approach Japan. The Third Fleet, under Admiral William "Bull" Halsey, with its big guns and naval aircraft, would provide strategic support for the operation against Honshu and Hokkaido. Halsey's fleet would be composed of battleships, heavy cruisers, destroyers, dozens of support ships and three fast carrier task groups. From these carriers hundreds of Navy fighters, dive bombers and torpedo planes would hit targets all over the island of Honshu.
The 3000 ship Fifth Fleet, under Admiral Raymond Spruance, would carry the invasion troops.
Several days before the invasion, the battleships, heavy cruisers and destroyers would pour thousands of tons of high explosives into the target areas. They would not cease the bombardment until after the landing forces had been launched. During the early morning hours of 1 Nov., the invasions would begin. Thousands of soldiers and Marines would pour ashore on beaches all along the eastern, south-eastern, northern and western coasts of Kyushu.
Waves of Helldivers, Dauntless dive bombers, Avengers, Corsairs and Hellcats from 66 aircraft carriers would bomb, rocket and strafe enemy defences, gun emplacements and troop concentrations along the beaches.
The Eastern A**ault Force, consisting of the 25th. 33rd and 41st Infantry Divisions, would land near Myasaki at beaches called Austin, Buick, Cadillac, Chevrolet, Chrysler and Cord and move inland to attempt to capture the city and its nearby airfield.
The Southern Force, consisting of the 1st Cavalry Division, the 43rd Division and America-L Division would land inside Amake Bay at beaches labelled DeSoto, Dusenberg, Essex, Ford and Franklin and attempt to capture Shibushi and to capture the city of Kanoya and its airfield.
On the western shore of Kyushu, at beaches Pontiac, Reo, Rolls Royce, Saxon, Star, Studebaker, Stutz, Winton and Zephyr, the V Amphibious Corps would land the 2nd, 3rd and 5th Marine Divisions, sending half of its force inland to Sendai and the other half to the port city of Kagoshima.
On 4 Nov., the reserve force, consisting of the 81st and 98th Infantry Divisions and the 11th Airborne Division, after feigning an attack off the island of Shikoku, would be landed - if not needed elsewhere - near Kaimondake, near the southernmost tip of Kagoshima Bay, at beaches designated Locomobile, Lincoln, LaSalle, Hupmobile, Moon, Mercedes, Maxwell, Overland, Oldsmobile, Packard and Plymouth.
Olympic was not just a plan for invasions, but for conquest and occupation as well. It was expected to take four months to achieve its objective, with three fresh American divisions per month to be landed in support of that operation if needed.
If all went well with Olympic, Coronet would be launched 1 March 1946. Coronet would be twice the size of Olympic, with as many as 28 American divisions landing on Honshu. All along the coast east of Tokyo, the American 1st Army would land the 5th, 7th, 27th, 44th, 86th and 96th Infantry Divisions along with 1st, 4th and 6th Marine Divisions.
At Samgami Bay, just south of Tokyo, the entire 8th and 10th Armies would strike north and east to clear the long western shore of Tokyo Bay, and attempt to go as far as Yokohama. The A**ault troops landing south of Tokyo would be the 4th, 6th, 8th, 24th, 31st, 32nd, 37th, 38th and 87th Infantry Divisions, along with the 13th and 20th Armoured Divisions.
Following the initial A**ault, eight more divisions -- the 2nd, 28th, 35th, 91st, 95th, 97th and 104th Infantry Divisions and the 11th Airborne Division -- would be landed. If additional troops were needed, as expected, other divisions redeployed from Europe and undergoing training in the United States would be shipped to Japan in what was hoped to be the final push.
Captured Japanese documents and postwar interrogation of Japanese military leaders disclose that information concerning the number of Japanese planes available for the defence of the home islands were dangerously in error.
During the sea battle at Okinawa alone, Japanese kamikaze aircraft sank 32 Allied ships and damaged more than 400 others. But during the summer of 1945, American top brA** concluded that the Japanese had spent their air force, since American bombers and fighters daily flew unmolested over Japan.
What the military leaders did not know was that by the end of July, the Japanese had been saving all aircraft, fuel and pilots in reserve, and had been feverishly building new planes for the decisive battle for their homeland.
As part of Ketsu-Go - the name for the plan to defend Japan -- the Japanese were building 20 suicide take-off strips in southern Kyushu with underground hangers. They also had 35 camouflaged airfields and nine seaplane bases.
On the night before the expected invasion, 50 Japanese seaplane bombers, 100 former carrier aircraft and 50 land based army planes were to be launched in a suicide attack on the fleet. The Japanese had 58 more airfields on Korea, western Honshu and Shikoku, which also were to be used for mA**ive suicide attacks.
Allied intelligence had established that the Japanese had no more than 2,500 aircraft of which they guessed 300 would be deployed in suicide attacks.
In August 1945, however, unknown to Allied intelligence, the Japanese still had 5,651 army and 7,074 navy aircraft, for a total of 12,725 planes of all types. Every village had some type of aircraft manufacturing activity. Hidden in mines, railway tunnels, under viaducts and in basements of department stores, work was being done to construct new planes.
Additionally, the Japanese were building newer and more effective models of the Okka -- a rocket-propelled bomb much like the German V-1, but flown by a suicide pilot.
When the invasion became imminent, Ketsu-Go called for a four-fold aerial plan of attack to destroy up to 800 Allied ships. While Allied ships were approaching Japan, but still in the open seas, an initial force of 2,000 army and navy fighters were to fight to the death to control the skies over Kyushu. A second force of 330 navy combat pilots were to attack the main body of the task force to keep it from using its fire support and air cover to protect the troop carrying transports.
While these two forces were engaged, a third force of 825 suicide planes were to hit the American transports.
As the invasion convoys approached their anchorages, another 2,000 suicide planes were to be launched in waves of 200 to 300, to be used in hour-by-hour attacks.
American troops would be arriving in about 180, lightly armed transports and 70 cargo vessels.
By mid-morning of the first day of the invasion, most of the American land-based aircraft would be forced to return to their bases, leaving the defence against the suicide planes to the carrier pilots and the shipboard gunners.
Japanese pilots crippled by fatigue would return time and time again to re-arm and fight. Guns would malfunction from the heat of continuous firing and ammunition would become scarce.
Gun crews would be exhausted by nightfall, but still the waves of kamikazes would continue. With the fleet hovering off the beaches, all remaining Japanese aircraft would be committed to nonstop suicide attacks, which the Japanese hoped could be sustained for 10 days.
The Japanese planned to co-ordinate their air strikes with attacks from the 40 remaining submarines from the Imperial Navy -- some armed with Long Lance torpedoes with a range of 20 miles -- when the invasion fleet was 180 miles off Kyushu.
The Imperial Navy had 23 destroyers and two cruisers, which were operational. These ships were to be used to counterattack the American invasion. A number of the destroyers were to be beached at the last minute to be used as anti-invasion gun platforms. Once offshore, the invasion fleet would be forced to defend not only against the attacks from the air, but would also be confronted with suicide attacks from sea. Japan had established a suicide naval attack unit of midget submarines, human torpedoes and exploding motorboats.
The goal of the Japanese was to shatter the invasion before the landing. The Japanese were convinced the Americans would back off or become so demoralised that they would then accept a less-than unconditional surrender and a more honourable and face-saving end for the Japanese.
But as horrible as the battle of Japan would be off the beaches, it would be on Japanese soil that the American forces would face the most rugged and fanatical defence encountered during the war.
Throughout the island-hopping Pacific campaign, Allied troops had always outnumbered the Japanese by 2 to 1 and sometimes 3 to 1.
In Japan it would be different. By virtue of a combination of cunning guesswork and brilliant military reasoning, a number of Japan's top military leaders were able to deduce, not only when, but where the United States would land its first invasion forces.
Facing the 14 American divisions landing at Kyushu would be 14 Japanese divisions, 7 independent mixed brigades, 3 tank brigades and thousands of naval troops. In Kyushu the odds would be 3 to 2 in favour of the Japanese, with 790,000 enemy defenders against 550,000 Americans.
This time the bulk of the Japanese defenders would not be the poorly trained and ill equipped labour battalions that the Americans had faced in the earlier campaigns.
The Japanese defenders would be the hard-core of the home army. These troops were well-fed and well-equipped. They were familiar with the terrain, had stockpiles of arms and ammunition, and had developed an effective system of transportation and supply almost invisible from the air. Many of these Japanese troops were the elite of the Army, and they were swollen with a fanatical fighting spirit.
Japan's network of beach defences consisted of offshore mines, thousands of suicide scuba divers attacking landing craft, and mines planted on the beaches.
Coming ashore, the American Eastern amphibious A**ault forces at Miyazaki would face three Japanese divisions, and two others poised for a counterattack. Awaiting the South-eastern attack force at Ariake Bay was an entire division and at least one mixed infantry brigade.
On the western shores of Kyushu, the Marines would face the most brutal opposition. Along the invasion beaches would be the three Japanese divisions, a tank brigade, a mixed infantry brigade and an artillery command. Components of two divisions would also be poised to launch counterattacks.
If not needed to reinforce the primary landing beaches, the American Reserve Force would be landed at the base of Kagoshima Bay 4 Nov., where they would be confronted by two mixed infantry brigades, parts of two infantry divisions and thousands of the naval troops.
All along the invasion beaches, American troops would face coastal batteries, anti-landing obstacles and a network of heavily fortified pillboxes, bunkers and underground fortresses.
As Americans waded ashore, they would face intense artillery and mortar fire as they worked their way through concrete rubble and barbed-wire entanglements arranged to funnel them into the muzzles of these Japanese guns.
On the beaches and beyond would be hundreds of Japanese machine gun positions, beach mines, booby traps, tripwire mines and sniper units. Suicide units concealed in "spider holes" would engage the troops as they pA**ed nearby.
In the heat of battle, Japanese infiltration units would be sent to wreak havoc in the American lines by cutting phone and communication lines. Some of the Japanese troops would be in American uniform. English-speaking Japanese officers were A**igned to break in on American radio traffic to call off artillery fire, to order retreats and to further confuse troops.
Other infiltrators with demolition charges strapped on their chests or backs would attempt to blow up American tanks, artillery pieces and ammunition stores as they were unloaded ashore.
Beyond the beaches were large artillery pieces situated to bring down a curtain of fire on the beach. Some of these large guns were mounted on railroad tracks running in and out of caves protected by concrete and steel.
The battle for Japan would be won by what Simon Bolivar Buckner, a lieutenant general in the Confederate army during the Civil War, had called "Prairie Dog Warfare." This type of fighting was almost unknown to the ground troops in Europe and the Mediterranean. It was peculiar only to the soldiers and Marines who fought the Japanese on islands all over the Pacific -- at Tarawa, Saipan, lwo Jima and Okinawa. Prairie Dog Warfare was a battle for yards, feet and sometimes inches. It was a brutal, deadly and dangerous form of combat aimed at an underground, heavily fortified, non-retreating enemy.
In the mountains behind the Japanese beaches were underground networks of caves, bunkers, command posts and hospitals connected by miles of tunnels with dozens of entrances and exits. Some of these complexes could hold up to 1,000 troops.
In addition to the use of poison gas and bacteriological warfare (which the Japanese had experimented with), Japan mobilised its citizenry.
Had Olympic come about, the Japanese civilian population, inflamed by a national slogan -- One Hundred Million Will Die for the Emperor and Nation -- was prepared to fight to the death.
At the early stage of the invasion, 1,000 Japanese and American soldiers would be dying every hour. Every foot of Japanese soil would have been paid for by Japanese and American lives.
Twenty-eight million Japanese had become a part of the National Volunteer Combat Force. They were armed with ancient rifles, lunge mines, sachel charges, Molotov ****tails and one-shot black powder mortars. Others were armed with swords, long bows, axes and bamboo spears.
The civilian units were to be used in night-time attacks, hit and run manoeuvres delaying actions and mA**ive suicide charges at the weaker American positions. The invasion of Japan never became a reality because on 6 August 1945, an atomic bomb was exploded over Hiroshima. Three days later, a second bomb was dropped on Nagasaki. Within days the war with Japan was at a close.
Had these bombs not been dropped and had the invasion been launched as scheduled, combat casualties in Japan would have been at a minimum in the tens of thousands. Every foot of Japanese soil would have been paid for by Japanese and American lives. One can only guess at how many civilians would have committed suicide in their homes or in futile mA** military attacks.
In retrospect, the 1 million American men who were to be the casualties of the invasion, were instead lucky enough to survive the war.
Intelligence studies and military estimates made more than 40 years ago, and no latter-day speculation, clearly indicate that the battle for Japan might well have resulted in the biggest blood bath in the history of modern warfare.
Far worse would be what might have happened to Japan as a nation and as a culture. When the invasion came, it would have come after several months of firebombing all of the remaining Japanese cities. The cost in human life that resulted from the two atomic blasts would be small in comparison to the total number of Japanese lives that would have been lost by this aerial devastation.
With American forces locked in combat in the south of Japan, little could have prevented the Soviet Union from marching into the northern half of the Japanese home islands. Japan today could be divided much like Korea and Germany before.
The world was spared the cost of Operation Downfall, however, because Japan formally surrendered to the United Nations 2 Sept. 1945, and World War 11 was over. In the fall of 1945, in the aftermath of the war, few people concerned themselves with the invasion plans.
Following the surrender, the clA**ified documents, maps, diagrams and appendices for Operation Downfall were packed away in boxes and eventually stored at the National Archives. These plans that called for the invasion of Japan paint a vivid description of what might have been one of the most horrible campaigns in the history of man.

Battles of Wake Island:
Wake Island has the distinction of being the only time defenders were able to prevent a landing during World War II. The marines and naval personnel on Wake, a refueling station for the Pan American Clipper, would become heroes to the American public starved for good news as the Japanese advanced across the Pacific.
Wake Island was 2000 miles west of Hawaii, across the International Date Line. Some 1600 civilian construction workers and servicemen were on the island, and they were attacked within minutes of the Pearl Harbor attack by Kwajalein-based bombers. On December 11, the defenders used their World War I issue 5-inch guns to repel a landing force and damage three cruisers and a destroyer.
By December 23, the island had been bombed and shelled for 12 days. Some 120 Americans and 880 Japanese died during the invasion. Public sentiment for the Wake Island garrison was heightened by the first American war movie, Wake Island, which was rushed into theatres within months.
The garrison was broken up. Most were shipped to China, while 98 men were left on Wake to construct defenses for the Japanese. The POWs sent to China were shocked by five random beheadings during the voyage. On October 7, 1943, Rear Admiral Shigematsu Sakaibara announced that he had executed the 98 men for radio contact with Hawaii.
The American command left Sakaibara and his 4400 men to wither on the vine, bypA**ing Wake. Wake was bombed and shelled repeatedly. American replacements used Wake as a training ground. Only 1200 men were let alive when the garrison surrendered on September 4, 1945. Sakaibara was arrested and tried for war crimes. He was executed in 1947.
