This shocked the French colonists, who feared that their capital city would be the next target. Québec did not have extensive fortifications in 1690, and the whole landward side of the city to the north and west was exposed, particularly at the Plains of Abraham. Count Frontenac returned to Canada for a second term as Governor-General, and ordered the construction of a wooden palisade to enclose the city from the fort at the Château Saint-Louis to the Saint-Charles River. Town Major Provost oversaw the construction of eleven small stone redoubts in this "enceinte", which would have protected against cannon. Facing the plains on the west side was the strong point of the landward defences — a windmill called Mont-Carmel where a three-gun artillery battery was in place. The palisade line ended on the east side of the city, near the hospital. The batteries facing the river were also improved, with eight guns mounted beside the Château and six 18-pounders at the docksides. Temporary obstacles had also been put in place on the street leading up to the upper city.
