In 1750, the first frontier fort, Fort Ohio, was built at Ridgeley. It was, at the time, the westernmost outpost of colonial civilization and was most commonly referred to as the "New Store" settlement at the time. The New Store was primarily a trading post created by the Ohio Company which included prominent members including George Mason and Lawrence Washington. There is evidence that Joseph Chapline, the founder of Sharpsburg, Maryland, who also was in charge of the construction of Fort Cumberland, organized the construction of the New Store settlement. The settlement was used for various purposes from 1750-1763. Early Ohio Company residents who worked at the settlement (and who explored the surrounding countryside) included Hugh Parker and Christopher Gist.
In May 1754, George Washington led a company of troops to meet Joshua Fry at the storehouses at Fort Ohio. Fry was a colonel and commander in the Virginia Militia. He was to take command of the forces sent to the frontier. Fry was thrown from his horse, died, and was probably buried in early Ridgeley as Fort Cumberland had not yet been built. Washington then took command of the troops, his first military command. Washington staged an attack from Fort Ohio against a French detachment of 40 men that resulted in the death of French diplomat Ensign Joseph Coulon de Jumonville. This action is considered the first shot fired in the French and Indian War.
In Spring 1755, Washington returned to the area to prepare for General Edward Braddock's attack on Fort Duquesne (commonly referred to as Braddock's March). Fort Cumberland was under construction at the time, and was used as the center of planning for the attack, while Fort Ohio was commandeered and used as well. Both a very young Daniel Boone (21) and Daniel Morgan (20) worked in the area to plan and carry out the ill-fated assault.
