6th Battalion, Ulster Defence Regiment was amalgamated to form part of what army?
Royal Irish Regiment (1992) The Royal Irish Regiment (27th (Inniskilling) 83rd and 87th and Ulster Defence Regiment) (R IRISH) is an infantry regiment of the British Army. The regiment was founded in 1992 through the amalgamation of the Royal Irish Rangers and the Ulster Defence Regiment. Their oldest predecessor; the 27th Regiment of Foot; was first raised in June 1689 to fight in the Williamite War in Ireland. Other notable regiments in their lineage include the Royal Inniskilling Fusiliers, Royal Irish Rifles and the Royal Irish Fusiliers (Princess Victoria's).
26th (Cameronian) Regiment of Foot The 26th (Cameronian) Regiment of Foot was a Scottish infantry regiment of the British Army, active from 1689 to 1881. Although the regiment took the name of its first colonel as The Earl of Angus's Regiment, it became popularly known as The Cameronians until 1751, when it was ranked as the 26th Foot. Under the Childers Reforms it amalgamated with the 90th Regiment of Foot (Perthshire Volunteers) to form the Cameronians (Scottish Rifles) in 1881. The Cameronians were themselves disbanded in 1968, meaning that no Army unit today perpetuates the lineage of the 26th Foot.
