terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania. Escalation in Ohio Country Governor-General of New France Marquis de la Jonquière died on March 17, 1752, and he was temporarily replaced by Charles le Moyne de Longueuil. His permanent replacement was to be the Marquis Duquesne, but he did not arrive in New France until 1752 to take over the post. The continuing British activity in the Ohio territories prompted Longueuil to dispatch another expedition to the area under the command of Charles Michel de Langlade, an officer in the Troupes de la Marine. Langlade was given 300 men, including French-Canadians and warriors of the Ottawa tribe. His objective was to punish the Miami people of Pickawillany for not following Céloron's orders to cease trading with the British. On June 21, the French war party attacked the trading center at Pickawillany, capturing three traders and killing 14 Miami Indians, including Old Briton. He was reportedly ritually cannibalized by some Indians in the expedition party. Construction of French fortifications In the spring of 1753, Paul Marin de la Malgue was given command of a 2,000-man force of Troupes de la Marine and Indians. His orders were to protect the King's land in the Ohio Valley from the British. Marin followed the route that Céloron had mapped out four years earlier. Céloron, however, had limited the record of French claims to the burial of lead plates, whereas Marin constructed and garrisoned forts. He first constructed Fort Presque Isle on Lake Erie's south shore near Erie, Pennsylvania, and he had a road built to the headwaters of LeBoeuf Creek. He then constructed a second fort at Fort Le Boeuf in Waterford, Pennsylvania, designed to guard the headwaters of LeBoeuf Creek. As he moved south, he drove off or captured British traders, alarming both the British and the Iroquois. Tanaghrisson was a chief of the Mingo Indians, who were remnants of Iroquois and other tribes who had been driven west by colonial expansion. He intensely disliked the French whom he accused of killing and eating his father. He traveled to Fort Le Boeuf and threatened the French with military action, which Marin contemptuously dismissed. The Iroquois sent runners to the manor of William Johnson in upstate New York, who was the British Superintendent for Indian Affairs in the New York region
