Battle of Isandlwana
The British army, commanded by Lord Chelmsford, invaded Zululand. The 24th foot made camp at Isandlwana where they were attacked by about 20,000 Zulus. Over 1,300 soldiers were killed. The Zulus themselves lost about 1,000 to 2,500 men.
The battle was followed by the successful British defence at the Battle of Rorke's Drift.
