The Kensington Regiment (Princess Louise's) is a unit of the British Army, which originated in the Volunteer Rifle Corps' movement of the 1850s.

The origins of the Kensington Regiment dated from 1859 with the formation of the Volunteer Force, part of a 'volunteer revival' as a result of a perceived French military threat, which had grown under the leadership of Napoleon III.

[1] 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.

The Regiment took its Latin unit motto Quid Nobis Ardui (English: Nothing is too arduous for us) from the Borough's Coat of Arms.

In November 1914 it departed England for France, and saw action on the Western Front, including the battles of Neuve Chapelle (1915), Aubers Ridge (the Regiment's defining action in the War) (1915), Somme (1916), Arras (1917), Passchendaele (1917), Cambrai (1917), Somme (1918), & the Hundred Days Offensive (1918).

The Battalion was broken up and demobilized in camps at Sidi Bashir in Egypt, and Mersin in Asia Minor in February to March 1919.

[8] During the Second World War the regiment changed its role from infantry to a heavy fire support unit armed with mortars, medium machine-guns and Oerlikon anti-aircraft guns.
