The Highland Light Infantry was a light infantry regiment of the British Army formed in 1881. It took part in the First and Second World Wars, until it was amalgamated with the Royal Scots Fusiliers in 1959 to form the Royal Highland Fusiliers (Princess Margaret's Own Glasgow and Ayrshire Regiment) which later merged with the Royal Scots Borderers, 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 2nd Battalion of the new regiment.

The 1st Battalion landed in France in September 1939 as part of the 127th (Manchester) Brigade in the 42nd (East Lancashire) Division for service with the British Expeditionary Force and then took part in the Dunkirk evacuation in June 1940.[10] As part of the 71st Infantry Brigade in the 53rd (Welsh) Division, it later took part in the Normandy landings in June 1944 and saw action at the Battle of the Bulge in January 1945, the Battle of the Reichswald in March 1945 and the final advance into Germany.
