Chronological Storyline (17 Milestones)

Dec 7, 1941 CE

USS Nevada Beached to Avoid Sinking

Having sustained heavy damage while attempting to sortie, the USS Nevada was deliberately beached at Waipio Point to avoid sinking in the harbor channel. This action prevented the ship from blocking the main navigable entrance to Pearl Harbor. · Wikipedia: https://en.wikipedia.org/wiki/USS_Nevada_(BB-36)

Japanese Pilots Consider Third Wave

Mitsuo Fuchida remained over Pearl Harbor to assess damage and relayed information to Admiral Chuichi Nagumo regarding the possibility of a third strike. Nagumo ultimately decided against launching a third wave, fearing increasing American resistance and risk to his carriers. · Wikipedia: https://en.wikipedia.org/wiki/Chuichi_Nagumo

Casualty Reports and Damage Assessment Begin

American forces began assessing the catastrophic damage to the Pacific Fleet, confirming over 2,400 military and civilian deaths. The devastating surprise attack galvanized American public opinion, leading directly to the United States declaring war on Japan the following day. · Wikipedia: https://en.wikipedia.org/wiki/Attack_on_Pearl_Harbor

View looks about east, with the supply depot, submarine base and fuel tank farm in the right center distance. A torpedo has just hit USS West Virginia on the far side of Ford Island (center). Other battleships moored nearby are (from left): Nevada, Arizona, Tennessee (inboard of West Virginia), Oklahoma (torpedoed and listing) alongside Maryland, and California. On the near side of Ford Island, to the left, are light cruisers Detroit and Raleigh, target and training ship Utah and seaplane tender Tangier. Raleigh and Utah have been torpedoed, and Utah is listing sharply to port. Japanese planes are visible in the right center (over Ford Island) and over the Navy Yard at right. U.S. Navy planes on the seaplane ramp are on fire.
