 On 12 December 1943 , General Vokes sent the three battalions of the 3rd Canadian Infantry Brigade against German defences in The Gully . The assault started poorly , when Canadian artillery plans were captured by soldiers of the 90th Panzergrenadier Division 's 200th Regiment . When The West Nova Scotia Regiment attacked The Gully , they were subject to counterattacks by the 200th Panzergrenadier Regiment approximately 10 : 30 . By 14 : 00 , the regiment had called off its attacks and had taken heavy casualties . To the west , Princess Patricia 's Canadian Light Infantry fared little better , with C Company taking heavy casualties in their assault . Attempts were again made on 13 December , by two battalions of the 3rd Canadian Infantry Brigade , and the attacks were driven back by <unk> German resistance . On the evening of 13 December , the heavily depleted 90th Panzergrenadier Division were relieved from their positions in The Gully by units of the 1st Parachute Division .
