The men remain in support in Cite St Pierre. This involves a number of tasks such as building a machine gun emplacement, construction of gas proof frames and curtains in their billeting area, transporting ammunition, and mostly trench improvements. Three hundred men are digging a new trench. The men are then relieved for a week before returning again to the front line on the 16th. This time they are back in familiar territory at Hill 70 near Loos. This is still an active area. The nights of the 18th thru the 20th are full of adventure. First a wring party is sent out, but promptly met by enemy machine gun fire. They quickly retreat, but without their leader who is assumed dead. Then the Germans put down intense trench mortar and pineapple (grenade) barrage and flatten a trench leading to one more death and seven wounded. The Canadians retaliate with 18 pounders, trench mortars and machine guns. The Germans could be heard screaming and groaning in their trenches. A Canadian is killed during one night of fighting. Another American shows up for Canadian War Lessons – this time a Lieutenant. The Germans try a surprise raid on a Canadian post but are taken by surprise by a returning Canadian wiring party. Fighting ensues resulting in one Canadian taken prisoner and one German left dead on the parapet in the Canadian trenches. Two other Germans are killed and a number wounded. One Canadian is missing and four are wounded . This is crazy. The Battalion is finally relieved, but there is no rest. The Germans start bombing Loos. On the last day of February the men are told to expect more bombing and to be on alert. The warning is merited. The Germans bomb Loos heavily. One more Canadian is killed in the bombardment.
