The 39th (Deptford) Divisional Artillery (39th DA) was a Royal Artillery force raised as part of 'Kitchener's Army' in early 1915. Recruited in Deptford, South London, the units served with the 'Pals battalions' of the 39th Division on the Western Front for two years. They saw action at the Somme, Ypres, and the German spring offensive, including the Battle of the Avre, described as 'one of the finest artillery stories of the whole war'. The units then operated as an independent artillery formation during the Allied Hundred Days Offensive.
