I have a friend of mine coming in next week end who was part of the invasion force of about 500,000 troupes that were ready to invade Japan until the Bomb was dropped.
I once heard this bizarre story about a troop train from the East Coast taking troops who had returned from Europe to the West Coast to assemble for the Invasion of Japan.
Apparently the train stopped for no apparent reason in a field in the middle of Nebraska. It sat there for 3 days. They had local townspeople bring in food, and the guys played pick-up baseball games on the Nebraska prairie to pass the time.
On Day 3 they brought radios in and let them all hear President Truman’s announcement and that the war was over.
