One hundred years ago on 15 September 1917
31st Battery, Canadian Field Artillery, Canadian Expeditionary Force was a sub-unit of the 9th Canadian Field Artillery Brigade in the 3rd Canadian Division. The 9th Brigade war diary records:
From this date to the 22nd inst., the Headquarters and four batteries mentioned herewith were in rest at MAGNICOURT, a small village nestling among some rolling hills. The men had a splendid rest during this time and many parties were sent for the day to ST. POL. In addition an infantry band was engaged on three different occasions which was very much appreciated. General sports for the men were held on two occasions and some Indian cavalry billeted near here very kindly offered to assist in the days sports. Their horsemanship and other feats were magnificent and filled our men with surprise and admiration.
31st Battery, Canadian Field Artillery was attached to 10th Canadian Field Artillery Brigade during this period. The 10th Brigade war diary records that:
Fine and warm. Capt. Davidson, M.C. made long tour of trenches on acheville front in attempt to find good O.P. for the show. No satisfactory point found. Heavy firing during practically whole night on Avion-Lens front. No attack developed. Quiet on Divisional front. Batteries stood to for two hours waiting a call.
Division on our right (31st) is carrying out concentrations during the night to cause casualties to the enemy and presumably to draw his attention from this front to theirs.
