In the East African campaign of World War I the British Royal Navy bombarded Sadani, first with the monitor Mersey on 26 July 1916 and then with the battleship HMS Vengeance on 3 August.
This led the German East African authorities in Sadani to surrender to British land and naval forces.
Both namesakes are served by nearby stations on the national railway network.
