AULNEAU (de La Touche), JEAN-PIERRE, priest, Jesuit; b. 21 April 1705 at Moûtiers-sur-le-Lay (department of Vendée); d. 8 June 1736.

Father Aulneau was the eldest of a family of five children. One of his brothers was a Jesuit; another, Michel, was a Sulpician, and his only sister was a nun at Fontenay. He studied at the seminary of Luçon, then on 12 Dec. 1720 he entered the noviciate at Bordeaux. He studied philosophy at Pau (1722–25), where he taught for a year, then he was a teacher at La Rochelle (1726–28) and Poitiers (1728–30). He studied theology in Poitiers (1730–34). On 12 Aug 1734, already a priest, he landed at Quebec, after a difficult crossing on the Ruby. On 15 August he was laid low by the illness that had wrought havoc on the ship, and on two occasions he was near death’s door. When he had recovered his health, he prepared for his theological examinations at the Jesuit college in Quebec and passed them during Lent the following year.

Father Aulneau was assigned to accompany those who were searching for the western sea, towards which La Vérendrye [Gaultier*] had begun to make his way. He was instructed to search out “new natives never seen before.” He was averse to leaving without the help of another priest, but he set out at the beginning of June 1735 to join La Vérendrye at Montreal. After spending two weeks at Sault-Saint-Louis with his friend, Father François Nau, he left Montreal on 21 June with the explorer. On 27 July he left Michilimackinac after an eight-day halt. Three hundred leagues of the journey were to a great extent covered in the midst of smoke and flames from a forest fire that had been lit by the Indians. On 23 October they finally landed at Fort Saint-Charles, which had been built in 1732. The post stood on the west shore of Lake of the Woods, in Cree country. The Assiniboins occupied another part of the same lake.

Father Aulneau was supposed to go on with the Assiniboins until they reached a tribe that was still unknown to the French, the Kaotiouaks or Ouantchipouanes, who were later called the Mandans. These Indians were said to be sedentary. They lived 250 leagues farther west, grew corn, owned horses, and hunted the buffalo. Their skin was white, and they were known for their gentleness. The Jesuit was supposed to learn their language and supply information concerning them.

In the spring of 1736 La Vérendrye sent his eldest son, Jean-Baptiste [Gaultier], to Michilimackinac with 19 men to get supplies. Father Aulneau went with them, to visit Father Saint-Pé*. On the first evening of their trip, 5 June 1736, the party stopped for the night on an island in Lake of the Woods. A band of Sioux surprised them early the next day. They were all massacred and decapitated. The bodies were found on 20 June, and on 17 September La Vérendrye had the bodies of his son and the missionary, together with the heads of the others, brought for burial in the chapel of Fort Saint-Charles. This disaster put an end to the project of a mission to the Mandans.
