'At Wulverghem on 2nd June 1917. When hostile guns were heavily shelling the Battery position a shell landed on a dump of boxed ammunition causing the the boxes to ignite. The fire obtained a good hold and a large explosion seemed imminent, when Gunner Belton and Fitter Selby, accompanied by their officer, rushed to the dump, and, regardless of the fact that the heat was causing shells to explode on all sides, separated the burning boxes from those untouched. When water arrived they ably assisted their officer to extinguish the fire. A heavy explosion resulting in the loss of several lives and the almost certain discovery of his Battery position was thus averted.'
