Crimean War (War of the Sontarans)

In an alternate timeline, the Crimean War was fought between Sontar and the British. With the help of the Thirteenth Doctor, the war ended in 1855 when the Sontarans - in the midst of a strategic withdrawal - were defeated by the British Army.

As with the original version of the war, (AUDIO: The Charge of the Night Brigade) Mary Seacole was present in Crimea, where she helped both British and Sontaran troops at her British Hotel. (TV: War of the Sontarans)
