Extract from 123rd Battalion war diary.
Born on 17 August 1895, James was a grocer before enlisting into the 123rd (Royal Grenadiers) Battalion on 13 December 1915 in Toronto. The battalion arrived in England on 19 August 1916 and continued their infantry training. In February 1917, while at Whitley Camp, they were faced with the prospect of being broken up to provide reinforcements for units already in France or proceeding to France as a pioneer battalion; they chose the latter. Arriving at Boulogne on 10 March 1917, they were designated as the pioneer battalion for the Canadian 3rd Division and, a month later, were involved in the assault on Vimy Ridge. The battalion afterwards served in various sectors during 1917 with the 4th Division and were moved up to Belgium in October to prepare for the 30 October attack on Passchendaele. Pte Calder was killed a few weeks later in the Salient on 11 November 1917 aged 22. He is buried at Ypres Reservoir Cemetery.
