(now in Pennsylvania) and likewise retreated eastward across the Appalachians. Washington proposed a series of frontier fortifications to protect settlers east of the Appalachians. Lewis initially built Fort Dinwiddie on the Jackson River of present-day Bath County, but was relieved of his command September 21, 1755. The Virginia assembly soon approved Lewis' promotion to major and assigned him to oversee the region along the Greenbrier River. On February 18, 1756, Lewis led the Sandy Creek Expedition from Fort Frederick with a mixed force of militiamen and Cherokees to raid the Shawnee towns along the Big Sandy and Ohio rivers to retaliate for Shawnee attacks. Lewis led several expeditions against both Indian settlements and French outposts. During the Forbes Expedition, Lewis was captured during Major James Grant's attack on Fort Duquesne in September 1758. Taken to Quebec, Lewis remained a prisoner until late 1759. Between wars The Proclamation of 1763 officially restricted Virginia's western expansion across the Appalachians, but Lewis continued his hunting and exploration trips into what later became West Virginia. When relative peace returned, Lewis entered politics. Three years after the formation of Botetourt County from Augusta County in 1769, Botetourt County voters elected Lewis and John Bowyer as their part-time representatives in the House of Burgesses and reelected the pair several times before 1780, though the grueling travel to Williamsburg or later Richmond, as well as the American Revolution precluded much attendance in later years. In 1774, Virginia's Governor Dunmore led a force to Fort Pitt and into the Ohio Country, in what became known as Dunmore's War. Lewis, now promoted to colonel, led a second force by a more southern route. Shawnee Chief Cornstalk attacked Lewis' force while it was camped at the Ohio River crossing at Point Pleasant. Lewis' victory in the Battle of Point Pleasant on October 10, 1774, secured his military reputation. Lewis became one of the founding trustees of Liberty Hall, formerly the Augusta Academy, along with his brother Thomas Lewis, Samuel McDowell, Sampson Mathews, George Moffett, William Preston, and James Waddel. In 1776 the academy was renamed in a burst of revolutionary fervor and relocated to Lexington, Virginia. Chartered in 1782 by the new Commonwealth of Virginia, Liberty Hall was again renamed, to Washington College. After the American Civil War it became Washington and Lee University, and is now the nation's ninth oldest institution of higher education. American Revolution When the American
