“Would appreciate a reference...The information I’ve seen indicates we’d outnumber them about 3:1.”
Same here. Where did you get the 3:1?
The final plan for Olympic called for 18 US divisions to attack 11 Japanese divisions. Don’t know about comparative size of the divisions.
I’ve seen claims the Japanese had 900,000 men on Kyushu by August.
The Japanese had plenty of men, but very limited stocks of fuel, equipment, ammo, etc. and almost no way to replace those stocks when used. Their combat power was not at all proportionate to their numbers.
Who knows what would have happened? What is very nearly certain is that the total number of casualties would have exceeded those of the A-bombs by at least an order of magnitude.
