The 51st Highland Volunteers (51 HIGHLAND) is a battalion in the British Army's Army Reserve or reserve force in the Scottish Highlands, forming the 7th Battalion of the Royal Regiment of Scotland, also known as 7 SCOTS. It is one of two Reserve battalions in the Royal Regiment of Scotland, along with 52nd Lowland (6 SCOTS), a similar unit located in the Scottish Lowlands. Originally formed as the 51st Highland Volunteers in 1967, as a result of the amalgamation of Territorial Battalions within the infantry Regiments of the Highland Brigade, the name commemorated the 51st (Highland) Division of the Territorial Force, within which many of the Regiment's antecedent Territorial Battalions served during the First and Second World Wars. History Origins and First World War The current Battalion traces its lineage back to the reserve Rifle Volunteer units that were originally raised in the Scottish Highlands as part of the Victorian Volunteer Force by Lord Lieutenants in every county. These included Highland units from the north-west of Scotland such as the Argyllshire Rifle Volunteers, the Inverness-shire Rifle Volunteers, the Ross-shire Rifle Volunteers and the Sutherland Rifle Volunteers. However, the lineage also includes elements of the Forfarshire Rifle Volunteers, the Perthshire Rifle Volunteers, the Fifeshire Rifle Volunteers, the Elginshire Rifle Volunteers, the Aberdeenshire Rifle Volunteers, the Banffshire Rifle Volunteers, the Renfrewshire Rifle Volunteers, and the Clackmananshire Rifle Volunteers. The current unit is the direct descendant of the infantry battalions that made up the 51st (Highland) Division, of which Highland Rifle Volunteer units became a part. This division was formed as part of the Haldane Reforms, which integrated the Volunteer Force, Militia and the Yeomanry into the nascent Territorial Force, created by the Territorial and Reserve Forces Act 1907. These units saw action as part of 51st Highland Division at the Battle of the Somme, the Battle of Arras, the Third Battle of Ypres and the Battle of Cambrai in France during the First World War. Interwar period and Second World War After the Armistice, the Territorial Force and its formations were disbanded. It was re-established, by the Territorial Army and Militia Act 1921, as the Territorial Army however, and the original Highland Territorial Battalions were reconstituted, although there were several amalgamations. During the Second World War these units again saw action as part of 51st (Highland) Infantry Division but many troops were detained as prisoners of war in Germany after more than
