Historical Section, Admiralty Naval Staff, 1st.ed., 1951. 148 pp., 2 tables (fldg.), 3 plans (cold. & fldg.) + 15 text ills. Blue cloth ; gilt ; ("Confidential" & "Restricted" run through). 25 x 16cm. Some rubbing & light wear to extremities of binding o/w V.G. The official Admiralty study of two U.S. naval battles in the Pacific during the Second World War, Coral Sea and Midway. Coral Sea occupies the first 55 pages and is illustrated with 2 folding coloured plans and 3 figures in text. Coral Sea was significant as being the first naval battle during which aircraft carriers engaged each other, and the first in which neither side’s ships sighted or fired directly upon the other. Both sides claimed victory and both sides exaggerated damage inflicted. This book examines the strategic situation in April 1942 ; the action at Tulagi, 4th May 1942 ; the action off Misima and Japanese air attacks on the 7th May ; and the air battles of the 8th May. Pages 57 to 148 cover Midway, illustrated with 1 large folding coloured plan and 12 text figures. Midway, in contrast, was a decisive American victory, taking place only six months after Pearl Harbour and a month after Coral Sea. The U.S. Navy inflicted devasting losses on the Imperial Japanese Navy that could never be replaced. Midway was the turning point in the Pacific War. This book examines the situation after Coral Sea ; preliminary moves, 3rd & 4th June ; air attack on Midway 4rth June ; attack on Japanese First Air Fleet the same day ; the destruction by US carrier aircraft of the First Air Fleet, and Japanese attacks on USS YORKTOWN, also 4th June ; pursuit of the enemy 5th June ; the last contacts on the 6th June and the sinking of YORKTOWN ; and finally the lessons and effects of the battle.
