On 17 October 1854, Hex arrived and helped clean the Scutari barracks and heal the sick within. The Seventh Doctor was recognised from the 25 September encounter with the Russians that he hadn't lived through yet, and was detained by them. The Doctor and Ace went back to 25 September, while Hex stayed behind for six weeks to meet his idol Florence Nightingale on 18 November. (AUDIO: The Angel of Scutari)
In 1814, the Eleventh Doctor, Amy Pond and Rory Williams visited London. Amy left the Doctor and Rory in a pub so that they could bond while she went sightseeing. Instead, they decided to use the TARDIS to skip ahead a few hours, while Amy encountered an agent of the Silence and became caught in the London Beer Flood.
During the same adventure, the Doctor and Rory visited London during the Blitz on this same day in 1940. While there, they saved Ian Fleming from a bomb and became the inspiration for James Bond. (COMIC: The Doctor and the Nurse)
