Fascinating, thanks for sharing that. I hadn't seen it before.

It doesn't surprise me that different military branches had different proposed plans - that's common. I wonder how much sway the Army had at that point? I'm pretty sure the Navy generally had more authority in Pacific operations since so much of the fighting was naval-based. Also, a lot of infantry in the Pacific campaign was the U.S. Marine Corps, who worked a lot more closely with the Navy than the Army during that era.

That said, the Air Force was actually a branch of the Army at that point - I'm not sure if it was Army or Navy planes that were involved in the raids and bombing of Japan. Edit: The Enola Gay which bombed Hiroshima was an Army plane. Which doesn't entirely answer the question.

Was MacArthur in favor of Operation Downfall? Pretty sure Admiral Nimitz wasn't...

I keep looking up Wikipedia links trying to figure it out, but not really getting great answers:

> A unified command was deemed necessary for an invasion of Japan. Inter-service squabbling over who it should be—the U.S. Navy wanted Nimitz, while the U.S. Army wanted MacArthur—was so serious that it threatened to derail planning. Ultimately, the Navy partially conceded, and MacArthur was to have total command of all forces, if circumstances made it necessary

Just spent about 10 minutes reading through that link and it's not quite clear who drafted the plans for Operation Downfall and who its proponents were vs. the blockade route.

I hadn't seen read about Operation Downfall before - I still wonder how much it was an option vs. a serious a consideration if the Japanese hadn't surrendered. Fascinating stuff - thanks for sharing.



Thanks for your very civil, truth-seeking reply! I don't usually notice or remember usernames on HN but I've noticed that in your comments before.

I don't know much more about Operation Downfall that you won't have already come across, but there is one detail you'll be interested in - from the Wikipedia article on Purple Hearts:

"During World War II, nearly 500,000 Purple Heart medals were manufactured in anticipation of the estimated casualties resulting from the planned Allied invasion of Japan...In 2003, there were still 120,000 of these Purple Heart medals in stock." - http://en.wikipedia.org/wiki/Purple_Heart


If the initial post war policy thinking is an indication (see Admiral's Rebellion), then the Army (w/Air Force) probably held sway.
