The Fall of Pearl Harbor in November 10 of the current Toaru Majutsu no Index timeline was a major victory by the Trident and GREMLIN forces led by Cinesic Evers over the military forces stationed at Pearl Harbor. The battle was unprecedented, and in the chaos of the invasion, the United States military could not properly mount a counterattack against Trident, and were forced to retreat. Despite their victory however, Trident quickly abandoned Pearl Harbor in order to search for Lindy Blueshake.
