When the Territorial Force was created in 1908 under the Haldane Reforms, the existing volunteer units in the London area were brought together into a new London Regiment and organised into two divisions with a full complement of infantry brigades and supporting arms.

[7][8][9][10] In October 1914, 2nd London Division was selected for service on the Western Front and progressive training was carried out through the winter.

[2][3][15] 141 Bde was reformed with its original battalions, and with brigade HQ at the Duke of York's Headquarters.

[16] In the 1930s, reorganisation of the TA saw the brigade's units being retasked (the 19th and 20th Bns became searchlight regiments in 1935) and posted away.

Between April and October 1944 it was responsible for an embarkation sector in Southampton for the Normandy landings.
