The 33rd Divisional Artillery (33rd DA), popularly known as the Camberwell Gun Brigade, was a Royal Artillery force raised as part of 'Kitchener's Army' in early 1915. Recruited in the Borough of Camberwell, South London, the units served with the 'Pals battalions' of the 33rd Division on the Western Front for three years. They also supported other formations when 33rd Division was out of the line. The batteries saw action at the Somme, Arras, and Ypres, suffering heavy casualties. They were particularly distinguished defending against the German spring offensive of 1918, and continued through the victorious Allied Hundred Days Offensive.
