<P> Céloron's expedition arrived at Logstown where the Indians in the area informed him that they owned the Ohio Country and that they would trade with the British colonists regardless of the French . He continued south until his expedition reached the confluence of the Ohio and the Miami rivers, which lay just south of the village of Pickawillany, the home of the Miami chief known as "Old Briton". Céloron threatened Old Briton with severe consequences if he continued to trade with British colonists, but Old Briton ignored the warning . Céloron returned disappointedly to Montreal in November 1749 . </P> <P> Céloron wrote an extensively detailed report . "All I can say is that the Natives of these localities are very badly disposed towards the French," he wrote, "and are entirely devoted to the English . I don't know in what way they could be brought back ." Even before his return to Montreal, reports on the situation in the Ohio Country were making their way to London and Paris, each side proposing that action be taken . Massachusetts governor William Shirley was particularly forceful, stating that British colonists would not be safe as long as the French were present . </P> <P> In 1749, the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country . The grant required that it settle 100 families in the territory and construct a fort for their protection . But the territory was also claimed by Pennsylvania, and both colonies began pushing for action to improve their respective claims . In 1750, Christopher Gist explored the Ohio territory, acting on behalf of both Virginia and the company, and he opened negotiations with the Indian tribes at Logstown . He completed the 1752 Treaty of Logstown in which the local Indians agreed to terms through their "Half - King" Tanacharison and an Iroquois representative . These terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania . By the late 17th century, the Iroquois had pushed many tribes out of the Ohio Valley, and they laid claim to it as their hunting ground by right of conquest . </P> <P> The War of the Austrian Succession (better known as King George's War) formally ended in 1748 with the signing of the Treaty of Aix - la - Chapelle, which was primarily focused on resolving issues in Europe . The issues of conflicting territorial claims between British and French colonies were turned over to a commission, but it reached no decision . Frontier areas were claimed by both sides, from Nova Scotia and Acadia in the north to the Ohio Country in the south . The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland . </P>
