Mailly-Maillet was within the line taken over from the French in the summer of 1915, and several Commonwealth cemeteries were made in the commune. Mailly Wood Cemetery was begun with the burial of thirteen men of the 2nd Seaforth Highlanders who died on 25 June 1916, and in November 1916, the 51st (Highland) Division buried in it following the capture of Beaumont Hamel. Thereafter, the cemetery was little used until April-August 1918, when the German attack on Amiens brought the front line very close, and further burials were made by the 12th Division (in May) and the 21st (in August), among others. After the Armistice graves from the battlefields immediately north-east of the village were brought into the cemetery, and 30 graves from MAILLY MAILLET MILITARY CEMETERY in the village itself.

The cemetery now contains 702 burials and commemorations of the First World War. 60 of the burials are unidentified and there are special memorials to two casualties whose graves in the cemetery could not be found, and to six whose graves in the military cemetery were destroyed by shell fire. The cemetery was designed by Sir Reginald Blomfield.

An extract from "The London Gazette," No. 30967, dated the 18th Oct., 1918, records the following:-"For most conspicuous bravery and initiative when in command of a platoon in support of forward platoons which had been ordered to hold on at all costs. When the enemy counter-attacked in force, he rushed forward on his own initiative to help the forward line, rallying and controlling the men holding it. The enemy by this time were advancing quicky, and had already obtained a footing in the trench. Serjt. Colley then formed a defensive flank and held it. Out of the two platoons only three men remained unwounded, and he himself was dangerously wounded.  It was entirely due to Serjt. Colley's action that the enemy were prevented from breaking through, and were eventually driven off. His courage and tenacity saved a very critical situation."
