'Gallantry and devotion to duty. On 30th September 1916 in Flers Support Trench during heavy shell and machine gun fire Captain Barrowclough led his Company in capturing about 400 yards of the trench. At one time the bombers came under British Stokes Gun Fire and had to retire. Captain Barrowclough went forward and by personal example inspired the bombers to continue. The operation was particularly difficult as a Company of a British Regiment had failed in the task the previous day. His coolness inspired his men to further efforts. By his success he materially assisted the Brigade on the left to capture and hold the position in front of Eaucourt l'Abbaye.'
