The successful defence of the mission station of Rorke's Drift, under the command of Lieutenants John Chard of the Royal Engineers and Gonville Bromhead, began when a large contingent of Zulu warriors broke off from their main force during the final hour of the British defeat at the day-long Battle of Isandlwana on 22 January 1879, diverting 6 miles to attack Rorke's Drift later that day and continuing into the following day.
