Neil Weir died in 1967, but it was not until 2009 that his grandson, Mike Burns, discovered his diary among some boxes he had been left, and learnt that his grandfather had served as an officer in the 10th Battalion Argyll and Sutherland Highlander throughout the First World War, seeing action at Loos, the Somme and Vimy Ridge, as well as in staff and training posts. It ends with his work at the War Office during the Russian Civil War of 1919-20.
