In mid-April 1942, the aircraft carriers Hornet and Enterprise were vulnerable to submarine attack as they sped toward Japan on their mission to launch Col. Jimmy Doolittle on his now famous raid on Tokyo and four other Japanese cities.
What if there had been a lucky Japanese submarine lurking in those waters? What if the US Navy's calculated risk hadn't paid off and the two carriers were lost and therefore not available for the Battle of Midway a month and a half later?
Interviews with Col. CV Glines and Col. Bill Bower plus extensive research at the National Archives and Naval Historical Center in Washington DC have been blended into an accurate but fictional tale of the Navy's contribution to that raid and the submarine force's astonishing performance against overwhelming challenges at the beginning of the war in the Pacific.
