John enlisted on the 16th of September 1914, twelve days after war was declared. He trained as an officer, and was gazetted Second Lieutenant on the 30th of December. He served in Gallipoli until the evacuation of Suvla Bay the following December, and then moved to Egypt in February, and on to France in June. He died on the 2nd of October 1917 from wounds recieved the same day, in the Ypres salient.
His Commanding Officer wrote: "I had only been 13 days with the battalion when he was killed, eight of which were spent in the lines. This was quite sufficient to show the sterling qualities of your son. He was a most charming character, a good comrade and a splendid soldier. He died a soldier's death. He was killed instantaneously by my side by a shell. The battalion had just been relieved when he was killed".
John was mentioned in Despatches by Sir Douglas Haig for gallant and distinguished service in the field.
