November

 * 9 - The Seventh Doctor and Ace arrived in Munich just as the Beer Hall Putsch concluded. Hitler and other members of the Kampfbund had been driven away from the War Office by soldiers. To Ace's surprise, the Doctor told Hitler he mustn't give up and would one day rule Germany. Hastily explaining his actions were necessary to insure that Earth history ran its proper course, the Doctor ushered Ace back to the TARDIS, where they were fired upon with an energy weapon, a sign that a non-contemporaneous person had been manipulating the past.
