The news of this disaster and the fear of a terrible uprisal at the hands of the frustrated Iroquois caused the governor to issue the ordinance of March 18, 1658, which was promulgated by Bénigne Basset, the successor to Notary Saint Père. In this the habitants were again ordered as formerly to provide themselves with arms and to fortify their houses; not to endanger their lives, but to work as far as possible in groups; to retire to their homes at the sound of the bell at night and not to leave until next morning without absolute necessity. They were not to go far for their hunting expeditions without special permission, and they were not to use any of the canots or chaloupes that were not their own without the express consent of the proprietors, unless it was a case of saving life.
Such precautions as these manifested the prudence of the governor and was the reason why there had been only one Frenchman killed between the date of the Point St. Charles massacre, October, 1657, to April, 1660. This solitary death was that of Sylvester Vacher dit Saint Julien, who was slain in 1659 near the Lac des Loutres close to the town. We may mention here several of the means adopted this year and the following to secure public safety. On the east, a new mill was built on a rising mound, afterwards called Citadel Hill, which was later the site of Dalhousie Square and is now the site of the Viger station. This was fortified as a redoubt and, together with the old fort mill at Windmill Point on the west, guarded the river front.
In addition the Sulpicians built two fortified farmhouses as redoubts or citadels in the extreme ends of the settlement to guard the labourers there--that of Ste. Marie on the east and that of St. Gabriel, named after M. Gabriel de Queylus, on the west. M. de Queylus interested himself in city planning also and he mapped out the lines on which the city should extend. An important protection was also secured by the construction of a well of one hundred feet in diameter, built by Jacques Archambault at the order of the governor, "in the middle of the court," or of the "place d'armes" of the fort, as it read in the contract of October 8, 1658. So far the water used had been supplied by the river, but fear of invasion and siege, and possible burning of the fort by the Iroquois, rendered this precaution very wise. In the next year, 1659, a similar well was placed in the hospital garden by order of M. de Queylus, and in the following year, 1660, a third contract was signed by Jacques Archambault for Charles Le Moyne, Jacques Leber and Jacques Tessard, for the mutual assistance of their houses near the hospital; and during this year also a storehouse of 60 by 30 feet was built by Francis Bailly dit Lafleur in the interior of the fort to guard the grain of the hospital.
