Canadian error at Falaise or misinfomation?

If anyone can be blamed, its French tank division. Canadian and American troops helped Poles (Canadians finally supported Mace Hill and Americans helped into defence of Trun). French division had Germans easy to kill. They could attack from south and finally close the gap. It would let polish division regroup and close the pocket. However they decided not to attack.
Jaeger - no matter how hard Germans could fight. Into situation in the end of Calaise battle Germans could only move east. If all allies units did they job Germans would be destroyed. No tank can fight attacked from 3 sides and without air support. Discipline and training (Germans had both) is not important.

Lt.-Col. Worthington had shown great daring and dash in his night advance through the German 89th Infantry positions. A combination of factors ultimately led to the destruction of his battle group. Most notably was the error in direction, but loss of communication and the fact that this was their first battle also contributed to their eventual misfortune. The 4th Canadian Armoured Division was often criticized for a lack of offensive drive during the push to Falaise. The experience of Worthington Force illustrates the perils that can befall those who are tasked with missions that ultimately prove too daring in nature.

I am going to guess that was the reason they didn't want to advance in the dark. In that program I watched they didn't really know why they stopped after getting close to their objective but losing a battle group might have been enough to give them pause.
