Okinawa - The Last Great Battle of WW II in the Pacific
April 1, 1945 marked the beginning of the invasion of Okinawa and the 81-day land and naval battle that was the 
costliest of the war in the Pacific with over 12,000 allied and 100,000 Japanese killed. The ferocity of the battles and Japan's extensive use of Kamikazi attacks ultimately led to the decision to use the atomic bomb rather than invade Japan. Robert Gandt's, "The Twilight Warriors" provides a riveting account of this great final battle of the war. Winner of the 2011 Samuel Eliot Morrison prize for naval literature.
