The Cameronians (Scottish Rifles) was formed in 1881 under the Childers Reforms by the amalgamation of the 26th Cameronian Regiment and the 90th Perthshire Light Infantry. After the amalgamation, the 1st Battalion preferred to be known as "The Cameronians" while the 2nd preferred to be known as "The Scottish Rifles". The 2nd Battalion saw action at the Battle of Spion Kop in January 1900 during the Second Boer War.
