'On the 5th October 1916 at Delville Wood, this Battery was heavily shelled ? an 8" shell hit an ammunition dump belonging to the battery killing one officer and four men. The explosion blew in the back of one of the gun pits and set fire to the charges stored along the gun. In the pit at the time were six men who were stunned by the explosion, but being roused by the flames ran out, when they were but a few yards away cries were heard from the inside of the pit. Sergeant Salmon followed by a Bombardier endeavoured to return through the fire at the back of the pit, which was burning furiously among the ammunition. Seeing that it was hopeless they went to the front and so gained an entrance. Inside they found another gunner pinned down by the fallen beams and debris. With the ammunition burning close to them and the battery still under heavy shell fire, these two NCO worked at the wreckage and after a few minutes succeeded in releasing the gunner and removed him to the outer air. Sergeant Salmon unfortunately was killed in action on October 7th 1916.'
