Alternate timeline
In an Alternate timeline in which Nazi Germany won World War II and eventually conquered Africa as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Mau Mau Uprising was against Nazi rule in Kenya. The Luftwaffe was sent in immediately. On the orders of the Führer Adolf Hitler, they proceeded to carpet-bomb the tribal areas and wipe out most of the native population.

In the alternative timeline in which Sarah Jane Smith died on 13 July 1964 instead of Andrea Yates, Andrea visited Kenya on a holiday. (PROSE: Whatever Happened to Sarah Jane?)
