​One hundred years ago on 24 August 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:
Visibility fair.  Only one enemy plane was seen today and no balloons.  Enemy movement in the front areas was below normal, but the motor and lorry traffic on the MUERCHIN-CARVIN road was abnormal and our heavies took on several targets at different times of the day along this road, and one lorry was seen to be damaged. 
 
3rd Canadian Divisional Artillery war diary records:
BRAQUEMONT -  Visibility fair on account of mist. Enemy artillery harassed LOOS during the night and became very active in counter battery work. The shells seem to be coming from a new direction to the south and the shelling is very persistent. Our aeroplanes were active all day; only one or two enemy planes were observed. Much movement has been reported in back areas. Our batteries took many targets with good results, guns having been registered on points where movement had been seen and the crews standing to.  Ammunition expended A.1750. AX.592. HX.484. Guns in action 86 18-pdrs., 24 4.5" Hows.

ANGRES - During the month of August the Battery took part in the capture of Hill 70, also the taking of the Green Crasier and all the fighting on the Lens front. During this time the Battery was twice heavily shelled by 8” and on several occasions we were bombarded with Gas Shells.
 
1st Canadian Heavy Artillery Group war diary records:
Cabaret Rouge – Under the heavy strain of fierce fighting our infantry withdrew to original line.  6" howitzers of 9th Canadian Siege Battery dispersed several working parties with casualties.  Very good work is being done by all batteries of this group in "sniping" working parties and bodies of enemy infantry in back areas.  Carried out concentrations on Cite Du Nord and houses and approached to Lens.
