The second invasion, Coronet, was to involve at least twenty-two divisions against one million Japanese defenders at Honshu and the Tokyo Plain. Many people may not know what those kinds of numbers represent. To put this invasion in perspective, the invasion of Normandy saw , allied soldiers storm the beaches, made up of six American Divisions and six British Divisions.
Chapter "DOWNFALL"- The Plan for the Invasion of Japan
A few images below help depict the size of the Normandy Invasion. The invasion of Normandy is known as the largest invasion in modern history, and is known to have been very brutal. When comparing Operation Downfall to the Normandy invasion, it is difficult to grasp the horror and tragedy that would have ensued. On the 4th. It is quite obvious that the planners for this invasion, all enjoyed their motor cars, by naming all the proposed landing beaches after these famous vehicle names. Objective of Olympic. Not only was this operation an invasion plan, but was designed for conquest and occupation of Japan.
It was felt that four months were probably needed for its objective to be reached, and three divisions a month would, if needed, also be landed to back up the original forces.
Operation Coronet. If all went well and according to plan, Coronet would swing into operation on the 1st.

It was to be twice the size of Olympic, with up to twenty eight Divisions planned to land on Honshu. Along the coast east of Tokyo, the US 1st. Army would land the 5th, 7th, 27th, 44th, 86th, and 96th Infantry Divisions, plus two Marine Divisions, the 4th and 6th. Just south of Tokyo at Sagami Bay, the total 8th and 10th Armies would move north and east to grab Yokohama.
Troops landing south of Tokyo, would be the 4th, 6th, 8th, 24th, 31st, 32nd, 37th, 38th, and 87th Infantry Divisions, backed up by two Armoured Divisions, the 13th, and 20th. After the initial assault, these troops would be augmented by another eight divisions, namely the 2nd, 28th, 35th, 91st, 95th, 97th, and th Infantry, with the 11th Airborne Division backing them up. Logistics Required. The logistics needed, firstly to carry out this invasion, and then support these huge numbers of troops would be horrific, and one can but shudder at the thought of how much paper was needed to set up these plans, and then follow with the back up needed once the troops had battled to gain a beach head and then fought to exploit it.
The endless stream of food, gasoline, ammunition, medical needs, equipment, reserves of manpower etc that had to flow across the Pacific from both the United States and Australia would be an organisational nightmare. Numbers of Japanese Aircraft available to defend their Homeland.
By the northern summer of , top American planners held the view that Japan had exhausted their Airforce, as US bomber and fighter aircraft were flying over Japan essentially unmolested. But, the Japanese were deliberately husbanding their aircraft, fuel and pilots, holding them in reserve against the day that their country would be invaded by US forces.

Allied intelligence considered 2, Japanese aircraft were available, with perhaps an additional available to be deployed in suicide attacks. In fact, how very wrong these estimates were, in August of , the Japanese nation had 5, Army and 7, Navy aircraft, ie 12, aircraft of all types available to defend the Homeland.
In addition, a newer and more effective model of Okka, a rocket propelled bomb, like the German V-1, but flown by a sucide pilot, were being built and becoming available. Japanese plans to fight off the invading forces. Whilst the Allied invasion force was still in open seas and approaching Japan, a force of 2, Army and Navy fighters would battle to control the skies over Kyushu. A second group of Navy combat pilots would attack the Task Force, aiming to prevent its fire support, and provision of air cover for the troop transports. As the convoys of invasion ships closed on their proposed anchorages, another 2, suicide aircraft would be launched, at a time, hour after hour.
During the invasion of Lingayen Gulf in January , I had seen many kamikaze attacks on the bombardment group of ships, and also on the invasion fleet. I saw a large number of hits on ships with devastating results, eg, our sister ship HMAS Australia , only yards away from Shropshire , was hit five times by kamikaze aircraft, resulting in a large loss of life. It was my experience, that no matter how many of our aircraft flew the Combat Air Patrol, and no matter how intense the anti-aircraft fire from the fleet, a number of the determined enemy kamikaze pilots always got through, to then crash on the ship they had individually selected as a target.
To be subjected to such attacks, day after day, over a long period, becomes mind numbing, one can sense the slow lowering of morale in a crew, you start to think, we as a ship, and her company, and I, as an individual, cannot continue to be lucky, we escaped yesterday, we escaped again today, but: How much longer can we continue?

Will our time to become a victim come tomorrow? I can only reiterate, when President Truman made his decision to drop those two atomic bombs, and the Japanese accepted unconditional surrender, I was a happy and delighted young man of 23 years of age , I was going to live, I had survived WW2, I had been involved since September across all the oceans of the world since I was Submarine Attacks.
http://fensterstudio.ru/components/lorogup/hyqo-como-localizar-celular.php During the war, Japan lost submarines in the Pacific war, reports at the time of planning for Operation Downfall, suggest that 40 submarines were still available to attack the Invasion Fleet. The Story of the Japanese Submarine Fleet.
What ever the number of Japanese submarines still in existence might have been, they would be used to attack the invasion force, backed up by midget submarines, Kaiten, ridden and guided by a sucide pilot to become human torpedoes, plus motor boats packed with explosives. The Japanese hoped to be able to shatter the Allies morale, and force the invasion fleet to back off, and hopefully, from the Japanese viewpoint, accept a more honourable and face saving prospect than unconditional surrender.
In most of the Pacific fighting during the island hopping campaign, our forces always outnumbered the Japanese forces by at least 2to1, and at times at 3 to 1. The wags in my ship used to describe a US invasion force, they landed their supplies on the beach, built it up, and up, and still up, until it became so large that it then toppled over and crushed all the enemy. Japanese Defenders. To face the 14 US divisions that would invade Kyushu, would be at least an equal number of Japanese divisions, independent mixed brigades, 3 tank brigades and many thousands of naval troops.
The Japanese would be at a 3 to 2 majority, , versus , US troops.

The land forces were backed up by offshore mines, thousands of suicide scuba divers to attack the incoming laden landing craft, and then mine infested beaches. Sixth Army would lead the southern-most assault on the Home Island of Kyushu to secure airfields and anchorages to support the second stage, Operation Coronet, a decisive invasion of the industrial heartland of Japan through the Tokyo Plain, miles to the north, led by the First and Eighth armies.
A common theme in these works is their reliance on a relatively few declassified high-level planning documents. An attempt to fully understand how both the U. Hell To Pay examines the invasion of Japan in light of substantial new sources, unearthed in both familiar and obscure archives, and brings the political and military ramifications of the enormous casualties and loss of material projected by trying to bring the Pacific War to a conclusion by a military invasion of the island.
