Frederick entered the war in France on 18th August 1914. He was killed by shell fire =
The Official History states - "No 7 Field Ambulance had gone on to Chassemy, but came under severe fire there on the 14th, and lost 4 of the R.A.M.C. and 1 of the attached A.S.C. killed and 5 R.A.M.C. and 2 A.S.C. wounded."
The War Diary states - "About noon while I was preparing school at CHASSEMY for the reception of wounded, a shell came through the roof and killed 3 men RAMC. The village was severely shelled. 4 NCOs and men RAMC, and 1 ASC driver of No 7 Field Ambulance were killed and 6 wounded. 7 draught and 2 riding horses were killed. I GS wagon and water cart were badly damaged beyond repair."
Lt/Col Brereton wrote - "But until about the end of 1917 the place was deserted but for soldiers. Little evidence could be found then of its previous occupation by men of the BEF; but at least those who fell are not forgotten. Those men of the R.A.M.C. and the devoted ASC driver of the 7th Field Ambulance, lie buried side by side beneath one of the shady trees in the Petit Place, and round them the hand of the ever-gallant poilu has erected a stone enclosure, while crosses deck the heads of the graves and flowers rest upon them."
The four RAMC casualties were 17174 Pte Frederick Charles Wilson, 18291 Cpl George Johnstone, 4101 Pte John Charles Rowe, and 5012 John Randall Poole.
Frederick was the son of Charles Wilson; and the husband of Maud Boyd (formerly Wilson) of 13 Henley Road, Chester.
