In 1694 Marest was sent to Canada and chosen chaplain of an expedition under
Pierre Le Moyne d'Iberville that was being outfitted to try to take the
Hudson Bay region from the English. This was "contrary to my inclinations" he wrote, since he was anxious to work among the
Indians. The expedition sailed from Quebec on August 10 of that year in two frigates, the
Poli and the
Salamandre. Marest wrote a running account of the voyage. Near the end of August they reached the entrance to Hudson Bay. On September 24 they entered the
Nelson (Bourbon) River, next to the mouth of the
Hayes (Sainte-Thérèse) River. The English had built
York Fort at the mouth of the latter river. The
Poli anchored on the Nelson and the
Salamandre, with Iberville and Marest, on the Hayes. The
Salamandre was "near being lost" according to Marest before finally anchoring. On October 13, 1694, the French were ready to bombard the fort. They asked the English to surrender. On the 14th, the English, led by Thomas Walsh, brought a list of their conditions, written in Latin by the English minister, Thomas Anderson. Marest translated the conditions for the French, the English surrendered, and the French took possession of the fort. They renamed it
Fort Bourbon. Marest said a thanksgiving mass. During the long winter, the French, including Marest, developed
scurvy. Marest busied himself learning the native language, apparently from word lists supplied him before his arrival. He wrote a dictionary and translated the sign of the cross, some prayers and the
Ten Commandments. The following summer (1695) Iberville returned to France with his English prisoners. Marest remained behind with the
garrison of 80 men. In September 1696
Hudson's Bay Company ships retook the fort, and Marest was himself taken prisoner. He was sent to England, where he remained in prison for some months. ==Illinois Country==
