During the Second Boer War, the 2nd Battalion saw action at the Battle of Spion Kop in January 1900 and took part in the Relief of Ladysmith in February 1900. The battalion served in South Africa throughout the war, which ended with the Peace of Vereeniging in June 1902. About 570 officers and men left Cape Town on the SS "Britannic" in October that year, and was stationed at Aldershot after their return to the United Kingdom. The 5th and 6th (Militia) Battalions also served in South Africa, the 6th leaving with 650 men on 10 February 1900, and later beng involved in a sharp action at Luckhoff. The 5th battalion served in the last year of the war. The battalions were awarded the battle honours South Africa 1900–01 (for the 6th) and South Africa 1901–02 (for the 5th). All three Volunteer Battalions also found 'service companies' of volunteers who served alongside the Regulars, and gained the battle honour South Africa 1900–1902 for their battalions.
