Question: Which British fortification was a post of passage during a war launched in 1763 by a loose confederation of elements of Native American tribes, primarily from the Great Lakes region?

Pontiac's War (also known as Pontiac's Conspiracy or Pontiac's Rebellion) was launched in 1763 by a loose confederation of elements of Native American tribes, primarily from the Great Lakes region, the Illinois Country, and Ohio Country who were dissatisfied with British postwar policies in the Great Lakes region after the British victory in the French and Indian War (1754–1763).  Warriors from numerous tribes joined the uprising in an effort to drive British soldiers and settlers out of the region.  The war is named after the Odawa leader Pontiac, the most prominent of many native leaders in the conflict. <SEP> Fort Winnebago was a 19th-century fortification of the United States Army located on a hill overlooking the eastern end of the portage between the Fox and Wisconsin Rivers east of present-day Portage, Wisconsin.  It was the middle one of three fortifications along the Fox-Wisconsin Waterway that also included Fort Howard in Green Bay, Wisconsin and Fort Crawford in Prairie du Chien, Wisconsin.  Fort Winnebago was constructed in 1828 as part of an effort to maintain peace between white settlers and the region's Native American tribes following the Winnebago War of 1827.  The fort's location was chosen not only because of its proximity to the site of Red Bird's surrender in the Winnebago War, but also because of the strategic importance of the portage on the Fox-Wisconsin Waterway, a heavily traveled connection between the Great Lakes and the Mississippi River.  Fort Winnebago's location near the portage allowed it to regulate transportation between the lakes and the Mississippi. <SEP> The Indian barrier state or buffer state was a British proposal to establish a Native American state in the portion of the Great Lakes region of North America west of the Appalachian Mountains, and bounded by the Ohio and Mississippi rivers and the Great Lakes.  The concept of establishing such a state, first conceived in the late 1750s, was part of a long-term plan to reconcile the Indian tribes to British rule and diminish hostilities between the tribes and the British Army following its victory in the French and Indian War.  After the region was assigned to the United States in the 1783 treaty ending the American Revolutionary War, British officials pursued efforts to organize the various tribes within it into a sort of Confederation that would form the basis of an Indian state, independent of the United States and under their tutelage, as a way to protect their fur trade ventures in the region and to block anticipated American attacks upon their remaining North American possessions. <SEP>  The fort served as a staging area for the Forbes Expedition of 1758.  During the eight years of its existence as a garrison, Fort Ligonier was never taken by an enemy.  It served as a post of passage to the new Fort Pitt, and during Pontiac's War of 1763, was a vital link in the British communication and supply lines.  It was attacked twice and besieged by the Native Americans, prior to the decisive victory at Bushy Run in August of that year.  The fort was decommissioned from active service in 1766.  Today, there is a museum next to the reconstructed fort.  Inside the museum there are artifacts from the battle. Fort Ligonier is a British fortification from the French and Indian War located in Ligonier, Pennsylvania, United States.  An individual can take a guided tour of the fort, and on Fort Ligonier Days, the fort's cannons are fired.
