<P> These British military successes were resisted, with successes by the French and Native Americans . In 1756, a large force of French, Canadians, and their Native American allies led by Marquis de Montcalm launched an attack against the key British post at Fort Oswego on Lake Ontario from Fort Frontenac and forced the garrison to surrender . The following year Montcalm with a huge force of 7200 French and Canadians and 2400 Native Americans laid siege to Fort William Henry on the southern shores of Lake George, and after three weeks of fighting the British commander Monroe surrendered . Montcalm gave him honorable terms to return to England and not to fight for 18 months . But many of the Native Americans were hungry for scalps and loot, so when the British force with civilians were three miles from the fort they massacred about 1100 of the 1500 strong force . </P> <P> Then the following year the French had one victory and one defeat . The defeat was at the French fortress city of Louisbourg . The victory was at the strip of land between Lake Champlain and Lake George at the French fortress of Fort Carillon . The British force sent to capture Fort Carillon (held by just 3400 French regulars and marines with almost no militia or Indian support) was the largest ever seen in America (at that time) 16,200 British, American, and Iroquois troops under the command of the dull political General James Abercrombie (called Mrs. Nabbycrombie by his troops and aunt aubbie by his officers). This battle cost the British 2200 troops, several artillery pieces, and most of the morale of that British army; meanwhile French losses were around 200 killed or wounded . </P> <P> While the British Conquest of Acadia happened in 1710, the French continued to remain a significant force in the region with Fort Beausejour and Fortress Louisbourg . The dominant population in the region remained Acadian . In 1755, the British were successful in the Battle of Beausejour and immediately after began the expulsion of the Acadians . The intent of the expulsion, in military terms, was to neutralize the supposed military threat posed by the Acadian people and stop the vital supply lines they maintained for Louisbourg . </P> <P> In the meantime the French continued to explore westwards and expand their trade alliances with indigenous peoples . Fort de la Corne was built in 1753, by Louis de la Corne, Chevalier de la Corne just east of the Saskatchewan River Forks in what is today the Canadian province of Saskatchewan . This was the furthest westward outpost of the French Empire in North America to be established before its fall . </P>
