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. Three heavy barrages laid down on our trenches in neighborhood of Avion during the night. S.O.S. sent up but no infantry section followed. Otherwise quiet on the front. Lt. Col. Ralston D.S.O. inspected the wagon lines.

ANGRES - During the month we were bombarded with Gas shells on several occasions also shelled 8” and 5.9” losing a quantity of ammunition.
1st Canadian Heavy Artillery Group war diary records:
Cabaret Rouge – Period very quiet. Very little firing done whatever during this time. On 27th instant, at 17:00 hostile plane brought down one of our observation balloons over LA TARGETTE in flames. This plane returned at 19:00 and succeeded in bringing down another of our observation balloons over ABLAIN ST. NAZARE Church.
General Officer Commanding, Royal Artillery, Canadian Corps war diary records:
In the Field - Brig.- General MORRISON visited the batteries of the 13th Brigade, 5th CDA, and was much pleased with the work done at the positions and with the morale of all ranks. It is worthy of note that two Artificers whom he found working in the gun-pit - which had , on the previous night, received a direct hit by gas shell - and whom he immediately ordered to leave, later developed severe blistering and were evacuated to hospital. It is more likely that if they had remained in the gun-pit much longer, the men would have died from the effects of the gas.
