US divisions for Coronet 1946

Post by Larso » 08 Oct 2021 08:09

The US Pacific theater divisions were all assigned to either the 6th or 8th Armies. The US 1st army was to be transferred from Europe to assist with the second phase of operation Downfall.

I was sure I once read which European based divisions were allocated to the invasion of Japan. Now I can't seem to find a list of these, apart from the 13th and 20th Armoured being assigned to the 8th Army. I know the 86th was being transferred and I'm pretty sure the 13th Airborne was also slated to participate but does anyone have a complete list?

Perfect - thank you very much!

The 4th would've had a very long war by the end.
