The Kensington Regiment (Princess Louise's) is a unit of the British Army, which originated in the Volunteer Rifle Corps' movement of the 1850's. In 1908 it became a battalion of the London Regiment in the Territorial Force. It was an infantry regiment from 1908-1940, a heavy fire support unit from 1940-1945, and has been a Squadron of the Royal Signals since 1945.
In the year 1859 the 4th Middlesex V(olunteer) R(ifle) C(orps), and the 2nd (South) Middlesex V.R.C. were formed under the patronage of the 2nd Baron Truro and the Viscount Ranelagh respectively, from bands of the concerned patriotic citizenry of Mid-Middlesex in response to a then perceived threat of a military invasion of England (which at that time found itself in a state of military unpreparedness for such an event) by France under the authority of Napoleon III. After this fleeting threatening shadow from an ascendant France had passed without conflict's manifestation, these voluntary militias that had come to life maintained their formations, in what would become West London with the geographically expanding Capital's devourment of the old County of Middlesex, on a volunteer basis with the assistance of limited provisioning from the War Office, with the aim of acting as a reserve pool of military knowledge and resource in the Kingdom's civilian population that would augment its military capacity at times of national martial peril.
Men from both units voluntarily went out to South Africa with the City Imperial Volunteers, thereby earning their Corps the right to the Battle Honour of 'South Africa 1900-1902'.
In 1908 as part of the Haldane Reforms of the Kingdom's volunteer forces, the "Kensingtons" Regiment was formed in an amalgamation of the 4th Middlesex V.R.C. and the 2nd (South) Middlesex, V.R.C., the newly minted unit being titled the 13th London Regiment (Kensingtons), T.F.. It based itself at the old 4th Middlesex V.R.C.'s Head Quarters in the Borough of Kensington, which adopted it as its local Regiment and consented for the new Regiment to use its name in its formation's title. The Regiment took its Latin unit motto Quid Nobis Ardui (English: Nothing is too arduous for us) from the Borough's Coat of Arms. Her Royal Highness the Princess Louise, Duchess of Argyll consented to the use of her name by the Regiment and it became officially designated as the Princess Louise's Kensingtons.
