The village of Mametz was carried by the 7th Division on 1 July 1916, the first day of the Battle of the Somme, after very hard fighting at Dantzig Alley (a German trench) and other points. The cemetery was begun later in the same month and was used by field ambulances and fighting units until the following November. The ground was lost during the great German advance in March 1918 but regained in August, and a few graves were added to the cemetery in August and September 1918. At the Armistice, the cemetery consisted of 183 graves, now in Plot I, but it was then very greatly increased by graves (almost all of 1916) brought in from the battlefields north and east of Mametz and from certain smaller burial grounds.

Dantzig Alley British Cemetery now contains 2,053 burials and commemorations of the First World War. 518 of the burials are unidentified but there are special memorials to 17 casualties known or believed to be buried among them. Other special memorials record the names of 71 casualties buried in other cemeteries, whose graves were destroyed by shell fire. The cemetery was designed by Sir Herbert Baker.
