The Second Boer War was fought in Southern Africa between 1899 and 1902. In total over 3000 Queensland officers and men were sent to help the British forces to fight the war, most being mounted troops from the Queensland Mounted Infantry, the Queensland Imperial Bushmen and the Australian Commonwealth Horse. Nine contingents sailed from Brisbane between November 1899 and May 1902. Most (and probably all) contingents mustered and trained at Fort Lytton prior to embarkation.
