Which have broken the trick Japanese naval password, brand new You.S. Navy understood the important points of their bundle. Based on Naval-intelligence records, an attack push might possibly be launched out of Japan to Get 20, and a bit shortly after Can get twenty four, the new Aleutians and Midway might possibly be assaulted. The new Commander-in-Captain of one’s Pacific Collection, Admiral Chester W.
