He was the son of John and Ruth Dormer. The War Diary entry for the 22nd June 1917 records. SOUTH EAST OF EPEHY. At 1.30am The Germans attempted a raid on the BIRDCAGE, intending to block the communication trench by bombing and to raid the garrison. This plan was frustrated by rifle fire and 10 Germans were left on the wire of the communication trench, 3 being brought in wounded, all of whom subsequently died. Lt. P. M. TOULMIN, who was out on a patrol towards a German sap, returned hurriedly just before the bombardment, having evidently seen some Germans massing. He was caught in the barrage, and killed, with 4 others of the patrol. The casualties were 1 officer killed, 9 other ranks killed and 10 other ranks wounded.
