1938

October

 * 30 - Orson Welles and the Mercury Theatre performed an adaptation of H. G. Wells' The War of the Worlds on CBS Radio. The broadcast caused nationwide panic across the United States of America. Although calm soon settled as America realised it was only a play, unknown to the public some elements of the production were based on actual events. (BFA: Invaders from Mars)

Unknown dates

 * Adolf Hitler obtained the Validium Arrow, one of the key components of the Nemesis statue. Around the same time, the Nemesis statue passed Earth, heralding Hitler's annexation of Austria and the coming outbreak of World War II. (DW: Silver Nemesis)
 * In what became known as "the Cambridge University Fiasco," an archaeological team attempted and failed to open the Devil's Hump. (DW: The Dæmons)

 * Joe Louis beat German heavyweight challenger Max Schmeling in a New York boxing match. Cody McBride was amongst the spectators. (PDA: Illegal Alien)
 * The TARDIS, damaged by Mels' gun, crash-landed in Hitler's study in Berlin, inadvertently stopping the torture of Hitler by the Teselecta. Hitler was punched by Rory Williams and forced into a closet. In the confusion, Hitler shot Mels, causing her to regenerate, revealing herself as Melody Pond. Melody poisoned the Eleventh Doctor, shutting down his regenerative abilities. Having later captured Melody, one of the biggest war criminals in history, the Tesselecta computer told the Doctor that a religious order called the Silence wanted him dead. Amy Pond caused the crew to evacuate from ship to escape from the antibodies, releasing her daughter. After the Doctor succumbed to the poison, Melody used up her remaining regenerations to revive him, once she learnt that she would become his closest friend River Song one day. The Doctor then took River away to the Sisters of the Infinite Schism to recover. (DW: Let's Kill Hitler)
