 While Denonville pursued his campaign against the Seneca, Lamberville remained as chaplain at Frontenac, where he and a good part of the garrison came down with scurvy.He sometimes visited Fort Denonville, which the governor had built on the site of De La Salle's Fort Conti on the eastern bank of the Niagara River at its mouth, on Lake Ontario.By 1687, Lamberville was so ill he had to be removed to Montreal.
