Plan to Attack Pearl Harbor

The Commander and Chief of the Japanese Navy Admiral Isorku Yaamoto developed a plan to launch a surprise attack against the US fleet at Pearl Harbor. The successful British attack on Italian fleet at Taranto served as a model for the Japanese attack.

While negotiations between the US continued the Japanese planned their attack. They were aided by excellent intelligence information supplied by their consulate officials in Hawaii. On November 26, 1941 the Japanese fleet of 23 warships weighed anchor-destination Hawaii. Their plan; a surprise attack on the American fleet on the morning of December 7th by torpedo and dive bombers on the American fleet. The attack was to be combined with an attack by midget submarines on the fleet.
