Leslie (Trews)/Royal Stewart (Pipers kilts & plaids)

The King's Own Scottish Borderers was a line infantry regiment of the British Army, part of the Scottish Division. On 28 March 2006 the regiment was amalgamated with the Royal Scots, the Royal Highland Fusiliers (Princess Margaret's Own Glasgow and Ayrshire Regiment), the Black Watch (Royal Highland Regiment), the Highlanders (Seaforth, Gordons and Camerons) and the Argyll and Sutherland Highlanders to form the Royal Regiment of Scotland, becoming the 1st Battalion of the new regiment.

The regiment was raised on 18 March 1689 by David Leslie, 3rd Earl of Leven to defend Edinburgh against the Jacobite forces of James VII. It's claimed that 800 men were recruited within the space of two hours. The regiment's first action was at the Battle of Killiecrankie on 27 July 1689.
