The Invasion Plans
ww2dbaseAs the naval and air forces bombarded Japan, the Allied leaders planned the actual invasion, which was code named Operation Downfall. The responsibility of planning went to Douglas MacArthur, Chester Nimitz, George Marshall, Ernest King, Hap Arnold, and William Leahy. The inter-service rivalry between the US Army and US Navy was addressed by an agreement that, should situation deem necessary, US Army General Douglas MacArthur would assume total command. Regarding the Japanese capacity to defend the Japanese home islands, American planning assumed:
"That operations in this area will be opposed not only by the available organized military forces of the Empire, but also by a fanatically hostile population."
"That approximately three (3) hostile divisions will be disposed in Southern KYUSHU and an additional three (3) in Northern KYUSHU at initiation of the OLYMPIC operation."
"That total hostile forces committed against KYUSHU operations will not exceed eight (8) to ten (10) divisions and that this level will be speedily attained."
"That approximately twenty-one (21) hostile divisions, including depot divisions, will be on HONSHU at initiation of that operation Coronet and that fourteen (14) of these divisions may be employed in the KANTO PLAIN area."
"That the enemy may withdraw his land-based air forces to the Asiatic Mainland for protection from our neutralizing attacks. That under such circumstances he can possibly amass from 2,000 to 2,500 planes in that area by exercise of rigid economy, and that this force can operate against KYUSHU landings by staging through homeland fields."
ww2dbaseThe invasion plan called for two separate invasions.

My own dear dad, a sergeant in the Army Air Corps, had served in the European Theater, and had received his orders to report to the South Pacific. Thankfully, those orders were countermanded, and he returned to the States.
