However, several flaws were evident in the 1745-design, with the rampart's flanks being exposed against several high points further west of the city, and its hasty construction in the midst of a panic over a potential attack. The condition of the ramparts were in bad repair by 1759, with French commanders making note of its condition prior to the Battle of the Plains of Abraham. The condition of the ramparts was partly what led General Louis-Joseph de Montcalm to assemble his forces outside the walled city on the Plains of Abraham to meet the British; which resulted in the capitulation of Quebec. The city's ramparts were used by the British forces in the following year, allowing them to hold out against a French siege in 1760 until reinforcements arrived by sea. The ramparts were used again fifteen years later, when soldiers of the British Army and the Canadian militia held off another siege in 1775 by American forces.
