What went wrong we do not know, but it was not long before John was to redeem himself. He joined up to serve in The First World War. He enrolled in the First Battalion of the Royal Dublin Fusiliers with the Regimental Number 10814 using the name John McFarlane. Perhaps he decided to use a pseudonim in order to avoid comparison with his earlier Naval record. Although technically he remained a Private, in practice he rose to the rank of Acting Serjeant. Sadly he was killed in action on 8th July 1916. And the circumstances on this occasion were far from being 'aggravated'. On the contrary they must have been of considerable bravery for posthumously he was awarded the Military Medal. His name is recorded on page 9209 of the Supplement to the London Gazette on 21st September 1916. He is listed there as Cpl. J. McFarlane, Late Royal Dublin Fusiliers. Although I have tried to obtain the wording of a citation to tell us why he was awarded the honour, this does not seem to exist. It may be possible to discover the circumstances from a reference to the date of his death in a history of his Battalion.
John is buried in a Military grave at Doullens Communal Cemetery, Extension No.1. Doullens is a town in the Department of the Somme, approximately 30 kms. north of Amiens on the N25 road to Arras. The Communal Cemetery and Extensions lie on the eastern side of the town, about 270 meters south-east of the road to Arras. The Commonwealth War Graves Commission records his memory on a Certificate as follows:

Not only are there some spelling mistakes: McIlhagga, Azamor, Shankill, but John's age is two years out. Perhaps he said he was younger than he really was when he joined up.
