History of The London Scottish :
'A (London Scottish) Company, based at Westminster and Catford, can
trace its descent from the Highland Armed Association of London and
the Loyal North Britons, which had been raised in 1793 and 1803.
In 1859 the London Scottish Rifle Volunteers were raised, sponsored by
the Highland Society and the Caledonian Society of London, and
commanded by Lieutenant-Colonel Lord Elcho. The soldiers were given a
uniform of homespun cloth known as Hodden Grey to avoid inter-clan
rivalry and kilts today are still made of this distinctive material.
During the Boer War, the Regiment supplied contingents of Volunteers
who served with the Gordon Highlanders and those links survive still.
In 1908 the Volunteer Force ceased to exist and became the Territorial
Force. The 7th Middlesex (London Scottish) Volunteer Rifle Corps
changed its name to the 14th (County of London) Battalion, The London
Regiment (London Scottish).
The 1st Battalion was mobilised on 5 August 1914 and was the first
Territorial battalion to go into action against the Germans at
Messines, near Ypres on 31 October. The Battalion continued to serve
in France and Flanders throughout the War taking part in all the major
offensives. The 2nd Battalion served in France, the Balkans and
Palestine, while a 3rd Battalion was a Reserve Battalion and supplied
drafts to the other two. Two Victoria Crosses and nineteen
Distinguished Service Orders were awarded to members of the Regiment.
In 1920 the 1st Battalion was raised again on a peacetime basis. The
Honorary Colonel was Field Marshal Earl Haig from 1919-1928 and he was
succeeded in 1935 by HRH The Duchess of York, later HM Queen
Elizabeth, and then HM Queen Elizabeth, The Queen Mother. In 1936, the
Battalion appeared in the Army List as a Territorial Battalion of the
Gordon Highlanders and two years later recruited the 2nd Battalion.
The 3rd Battalion was formed from those on the waiting list, as a
Heavy Anti-Aircraft unit titled 97th HAA Regiment RA, TA (The London
Scottish).
The Regiment reformed in 1947 and following the TA restructuring of
1967, formed G (London Scottish) Company 1st Battalion 51st Highland
Volunteers. On the formation of The London Regiment in 1992 it became
A (London Scottish) Company.
