Little Boy, was designated the target of Hiroshima. The bomb run was successful and the bomb obliterated the city. The destructive power of Little Boy was roughly the equivalent of 13,000 tons of TNT. At least 100,000 Japanese men, women, children and babies burned to death.
Later, the Americans dropped Fat Man, an even more powerful plutonium bomb, on Nagasaki. (PROSE: Endgame) The city was also flattened. (COMIC: 4-Dimensional Vistas) Approximately 150,000 more people were killed by the Nagasaki bomb, bringing the total number of dead to a quarter of a million Japanese civilians. (COMIC: Sky Jacks) Further deaths among people from both cities occurred later as a result of radiation poisoning. (PROSE: Endgame)
The destruction of the two cities ultimately convinced Japan's rulers of the need to surrender. The Japanese Emperor was forced to give the order to do so. (COMIC: The Road to Hell) Japan surrendered to the Americans (PROSE: Log 384) on 2 September 1945, (COMIC: Sky Jacks) ending the Pacific War and thus fully bringing World War II to its formal conclusion. (PROSE: Base of Operations) The date became celebrated as VJ Day (PROSE: Deadly Reunion) or Victory in the Pacific Day. The Allies celebrated the occasion with what the Eleventh Doctor described as "one hell of a victory party." (COMIC: Sky Jacks)
