This is the story of the U.S.S. Yorktown and the Japanese carrier fleet and includes, aside from the Battle of Midway, the Battle of the Coral Sea. It is told from the points of view of the officers of the bridge, seamen below deck, pilots in the air and of the officer of the Japanese submarine that did the decisive damage that sank the Yorktown. Following the disaster at Pearl Harbor, a mere four U.S. aircraft carriers could be mustered for the defense of the Pacific. (Not a single carrier had been scratched on December 7th.) The Yorktown, commissioned in 1936, was a relatively new vessel as she set off to protect our remaining holdings in the Pacific and harry the Japanese fleet. After some action in the Marshall and Gilbert Islands, off New Guinea and Tulagi, she entered the Battle of the Coral Sea. Though our fleet was hit hard during this engagement, it significantly turned back the Japanese fleet and shook confidence of their navy. And Japanese carriers were put out of action that would otherwise have made the Battle of Midway an American shambles. Instead, the Yorktown contributed heavily to our success at Midway which meant that Japan had no further hope of invading Australia. Eyewitness reports of bomb explosions on deck, racing torpedoes, death and turmoil are gripping, as is the description of the ghostly decks of the abandoned ship.
