In critical circumstances, her advice was heeded, a bulwark against discouragement. […] During that year (1660) […] every inhabitant had to be ready for combat. The Iroquois had moved up the St. Lawrence and were threatening Quebec. […] The Ursuline monastery was abandoned and put under siege. Marie remained there alone with three companions to provide ammunition to the soldiers. […] At times, everything seemed to point to the loss of the colony. Marie identified with all these miseries, these difficulties, this general anxiety. […] But, as seen in her letters, she never despaired. It was perhaps due to a few kind-hearted women like herself, and to her Ursulines sisters, and to the Augustinian Hospital Nuns, in their resolution to stay, in spite of everything, that Quebec survived so many calamities!
