Born the son of Archibald Campbell, 17th Laird of Mains,[2] Barrington Campbell became a lieutenant in the Lanarkshire Yeomanry Cavalry on 15 October 1867.[3] He served with the 1st Battalion Scots Guards during the Anglo-Egyptian War in Egypt in 1882, and was present in the engagement at El Magyar and Tel-el-Mahuta, and the Battle of Tell El Kebir (13 September 1882).[4] He was awarded the Royal Humane Society Medal in 1889 for saving a life.[2] He was promoted to Major-General in 1898. Following the outbreak of the Second Boer War in late 1899, he was in early 1900 appointed in command of the 16th Infantry Brigade sent to serve in South Africa as part of the 8th Division under Sir Leslie Rundle. He left Southampton for South Africa on the SS Britannic in March 1900.[5] For his service in the war he was twice mentioned in despatches (including by Lord Kitchener dated 23 June 1902[6]), and appointed a Companion of the Order of the Bath (CB).

Following his return to the United Kingdom, he served as Lieutenant-Governor and Commander-in-Chief of Guernsey from 1903 to 1908.[2]
