Excerpts from Books and Wikipedia
"After the victory at Midway the impetus in the Naval Pacific War lay with the United States, and Japanese hopes for a quick and decisive victory were over." [Furtado: 1001 Days] "One month later, on June 5-6, the navy suffered another setback, losing four large aircraft carriers, one heavy cruiser, and approximately three thousand men, including 121 skilled pilots, in battles near Midway Island in the Central Pacific." [Hirohito, p. 449] "But American offensives always developed at a pace that outstripped the ability of the Imperial Army and navy to consolidate and respond effectively. Unable to read Allied radio messages (as the British and Americans could read theirs), the high command was never sure where to concentrate to meet Allied thrusts." [Hirohito, p. 470]
