Captain Mathew Arbuckle Sr., (July 15, 1740 – July 27, 1781) was a pioneering hunter and trapper of western Virginia (now West Virginia) and the Ohio territory. He is considered likely to have been the first white person to travel through Virginia all the way to the Ohio River, other than as a prisoner of the Indians. This trapping and trading trip may have occurred around 1764.
Arbuckle was born in Augusta (now Botetourt) County, Virginia, to James Arbuckle (1713–1783) and his wife Margaret (née Thompson) Arbuckle (1714–1761). He served in the Augusta County militia in 1758 and ’59. He was the first white man to travel the length of the “Great Kanawha” valley and records indicate that he reached the future site of Point Pleasant, at the confluence of the Kanawha and Ohio, around 1764. By 1767 he is listed as a lieutenant and in 1770 he was commissioned captain of (the newly formed) Botetourt County militia. He served as a “gentleman justice” of Botetourt County from its founding in 1769 until 1773. In 1774, he built the stockade on Muddy Creek, Greenbrier County, now known as Arbuckle's Old Fort.
After the outbreak of Lord Dunmore’s War in May 1774, Arbuckle both assumed command of a company of Botetourt County militia and served as guide and chief scout for General Andrew Lewis's late summer march to Point Pleasant. This led directly to the defeat Chief Cornstalk’s native forces at the Battle of Point Pleasant in October. Soon after the battle, Arbuckle had returned to Greenbrier County and established his residence near Fort Savannah, later known as Lewisburg. In 1776, Arbuckle built Fort Randolph at Point Pleasant and was in command in there the following year when a contingent of newly arrived and undisciplined militia witnessed one of their number killed and scalped by Indians. This mob overcame their officers' (including Arbuckle's) attempts to maintain order and famously murdered the captive Cornstalk, an event which cast a shadow over the region for decades.
