'For continuous gallantry and devotion to duty during active operations from 21st of August to 13th September 1918, at Miraumont, Fremicourt and east of Havrincourt Wood. As a Battalion runner Rifleman Corbett has by his excellent work, often under direct rifle and machine-gun fire rendered most valuable service in the engagements at Miraumont (23 August 1918), Fremicourt (31 August 1918) and east of Havrincourt Wood (12 September 1918). At times telephonic communication has been impossible owing to the wires being out by shell fire, and the Battalion has had to rely on runners who have kept in constant touch with the forward companies. At Havrincourt Wood this runner repeatedly passed through enemy barrages in order that the necessary information should reach Battalion headquarters. Corbett has at all times shown the utmost disregard of danger and his cheerfulness has been an inspiration to all.'
