One hundred years ago on 7 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:  Drew 18 19-pdrs today from Gouy Servins for the batteries to go into action. Drew stores from the 2nd C.D.A.C. at Souvigny. Bde. Hqrs. Moves up today. O.O. 131 and 132 issued—copies attached.
A later report of the enemy’s bombardment on the night of 4th/5th shows that the 39th Battery was called upon by the infantry for retaliation. This was quickly responded to in spite of the strafing. It was found impossible to serve the guns while the men wore gas masks, so these were discarded. Owing to the prompt treatment immediately after, no men were seriously affected. Unfortunately, however, the long march afterwards to the new wagon lines proved very hard on these men.
