This was the name of the American plan for the two phase invasion of Japan, due to start with Operation Olympic in November 1945 if the war had not been brough to an end beforehand. Apart from the British Pacific Fleet, it would have been an all American affair. These two links give good information on the plan and the planned Japanese defence: http://www.ibiblio.org/pha/war.term/olympic.html http://sandysq.gcinet.net/uss_salt_lake_ci...25/topsecrt.htm Up to a million US casualties were predicted. I only learned of this plan fairly recently and I bet it is largely unknown to many in Britain who otherwise know a lot about WWII. What are your thoughts?
