He served with the regiment in South Africa during the Second Boer War, from June 1900 he took part in operations in Transvaal. He was again seconded for service in South Africa in April 1902, when he commanded a mounted infantry contingent. The war ended two months later, and Spring left Cape Town in the SS Dunera in late September 1902, arriving at Southampton early the following month. Spring was adjutant of the 2nd Battalion of his regiment between 1904 and 1907, and was promoted to captain in 1905.
