Work near Rosieres on 19 August 1918.
Recommendation date: 21 August 1918

'For conspicuous gallantry and devotion to duty. In the vicinity of VILLERS BRETONNEUX on the 2nd June 1918, while the forward section of his Battery was being heavily bombarded, Sergeant DEAN behaved in a very gallant manner in leaving a place of comparative safety to extinguish a fire which had extended from an adjoining gun pit that had been demolished and threatened to envelope the remaining gun and ammunition. This action undoubtedly saved considerable damage to material and set a splendid example to his fellow comrades.'

'For conspicuous gallantry and devotion to duty. On the 19th August 1918 the 42nd Battery - in action to the East of ROSIERES (SE of VILLERS BRETONNEUX) - was heavily shelled by 4.2s and 5.9s. Several shells fell right on the position, wounded the Battery cammander (Major S.F. BODGENS, D.S.O.), ignited the camouflage and started a fire in a gun-pit. Sergeant DEAN and two others, at a great personal risk, remained at the position and carried the wounded officer to a place of safety. This done, he immediately returned to assist in extinguishing the fire. This timely and brave action probably saved the life of the Officer mentioned and prevented the guns and ammunition from being destroyed during a critical period.'
