Alternate timeline (War of the Sontarans)

In one alternate timeline created by the Sontarans during their Flux assault, an alternate Crimean War was fought between British troops and an army of Sontarans, led by Commander Skaak, (TV: War of the Sontarans) who wanted to reclaim Earth in honour of Commander Linx, (TV: The Time Warrior) and chose the Crimean War for its opportunity for bloodshed and because he wanted to ride a horse.

According to the British map, Russia and China were replaced by Sontar in this timeline. While looking at the map, the Thirteenth Doctor stated that Britain, Jamaica and Crimea were in the right places.

The timeline was later aborted when Dan Lewis and Karvanista piloted a Sontaran timeship into a temporal collision with the rest of its fleet in 2021 Liverpool, thus erasing the Sontarans' Flux assault from history. (TV: War of the Sontarans)
