 By the morning of 9 December , the <unk> had completed the bridge across the Moro River , enabling the tanks of the 14th Armoured Regiment ( The Calgary Regiment ) to transport two companies of Seaforth Highlanders across the river into San Leonardo . By mid morning , San Leonardo had been cleared of German defenders , although strong positions still existed outside of the town . Within an hour , the <unk> ' tanks had broken through German positions near <unk> Castle and two companies had linked up with the 48th Highlanders and Princess Patricia 's Canadian Light Infantry within San Leonardo , finally establishing firm Canadian positions across the Moro River . Near the end of 9 December , German forces of the 90th Panzergrenadier Division fell back to their second defensive line : a formidable obstacle known as " The Gully " .
