James Lochhead Jack

Brigadier-General James Lochhead Jack (1880 – 22 December 1962) was a British Army officer who fought during the First World War. In 1964, his diaries were published (edited by John Terraine) and became a bestseller.

Military career Jack was commissioned as a second lieutenant in the 4th (Militia) Battalion of the Argyll and Sutherland Highlanders on 14 January 1903. The militia battalions were reserve regiments, and the 3rd battalion was headquartered in Stirling.

In September he transferred to the Regular Army and the Cameronians (Scottish Rifles). By now aged twenty-three, "his Regular military career had made something of a late start", although he had served in the Second Boer War with the Scottish Horse and the 1st Battalion of the Argylls. In November 1908 he was appointed as an adjutant of the 1st Battalion of his regiment, holding this position until 1911 when he became a company commander. Jack was to serve with the brigade headquarters as its staff captain from 28 August until 2 November before returning to his battalion.

Personal life He was married to Jeanette Watson (1902–1996) and was survived by her and two sons, Kenneth and Angus.
