At about 01: 00 hours on June 19th 1921, a cycle patrol under my command was operating in the village of Drumlish, Co. Longford. Section Leader F.W. Osman and Temporary Cadet C.G. Hughes were about 200 yards down the road in order to rouse the occupants of a shop to get a spare part for a bicycle. I heard firing coming from that direction. I went to the scene and found them engaging two men; one of them vanished over a wall and the other lay groaning on the ground. The latter died almost immediately. He was wearing a Sam Browne belt and revolver holster and had in his pocket an egg bomb and a dispatch addressed to the “Police Officer, Longford Brigade”. I subsequently removed the body to the military mortuary at Longford, where it is now lying. I saw a wound in his shoulder, one in his left leg and one over his heart
