Peter Mackintosh was born on 6th October 1887 in Inverness. In 1901 the Mackintosh family were living at 22 Ballantine Place, Perth: Father, Alexander (Railway Guard), b. c1861, Knockbain, Ross-shire; Mother, Annie, b. c1860, Avoch, Ross-shire; Son, Peter, b. 1887, Inverness; Daughter, Marion, b. c1895, Perth; and Son, Alexander, b. c1899, Perth. 

He married Margaret Edna Dack on 26th July 1915, shortly before he enlisted in the 67th Pioneer Battalion of the Canadian Engineers. Before he enlisted Peter was employed as an Accountant with the Bank of Nova Scotia at their main branch in downtown Victoria. The 67th Pioneer Battalion were part of the 4th Canadian Division, which was formed in Britain in April 1916 from several existing units, and others scheduled to arrive shortly thereafter.

Under the command of Major-General David Watson, the Division embarked for France in August of that year where they served both in France and in Flanders until Armistice Day.

Extract from the War Diary of the 67th “Western Scots” Pioneer Battalion “Voormezeele, 9-9-16. “ ‘C’ Co. 6 day parties - 3 Officers, 2 Sergts.& 69 O.R. 3 night parties - 1 Officer, 2 Sergts. & 48 O.R. 1 pte. wounded. Heavy bombardment of Voormezeele in afternoon. Lieut. Mackintosh severely wounded - 1 O.R. killed, 7 wounded.”

The village of Lijssenthoek was situated on the main communication line between the Allied military bases in the rear and the Ypres battlefields. Close to the Front, but out of the extreme range of most German field artillery, it became a natural place to establish Casualty Clearing Stations.

Peter Mackintosh died as a result of his wounds, probably in one of these Casualty Clearing Stations, on 10th September 1916. He was 28 years old.

Peter Mackintosh is also commemorated on the Perth West Church War Memorial; and the Roll of Honour of the Bank of Nova Scotia.
