Someone forwarded this to me and even though the subject has probably been worn, I thought I'd share it. Here's the beginning:
--------------------------
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 declassified, 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 defenses the Japanese had prepared to counter the invasion had it been launched. Operation Downfall was finalized during the spring and summer of 1945. It called for two massive 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 assault during the early morning hours of November 1, 1945. 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 - 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 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, elements of the 7th Army Air Force, the 8th Air Force (recently deployed from Europe), the 10th Air Force, and the American Far Eastern Air Force. More the 1.5 million combat soldiers, with 3 million more in support or more than 40 percent of all servicemen still in uniform in 1945 - would be directly involved in the two amphibious assaults. Casualties were expected to be extremely heavy.
--------------------
It's one of the more interesting what-ifs? of the 20th century in my opinion. Even with conservative estimates, the "Battle of Japan" could have surpassed the Battle of Stalingrad (approx. 2 million casualties in 168 days) as the bloodiest battle in human history.
This guy did some research and painted an even costlier picture than many.
And one more extra source for additional info.
