Attack on Donnally's Fort.
-In May, 1778, a body of about two hundred Indians, determined to avenge the death of their chieftain, Cornstalk, began a siege of Fort Randolph, at Point Pleasant, then garrisoned by a detachment of Virginia troops, commanded by Lieutenant McKee. A determined resistance was continued for a week, at the end of which time the siege was raised, and the Indians, instead of returning north of the Ohio, proceeded up the Kanawha.

Lieutenant McKee, believing their object to be the destruction of the Greenbrier settlement, dispatched two men to notify the settlement of the advance of the Indians. After following them several days they became frightened and returned to Point Pleasant. Captain McKee then formed his men in line and asked if there were any two among them, who would volunteer to go to the Greenbrier country and warn the people of their danger. John Prior and Philip Hammond stepped from the ranks and replied "We will."

The Grenadier Squaw, a sister of Cornstalk, but a friend of the whites, painted them as savages, and though the Indians were far in advance, still by traveling night and day, they were enabled to overtake them, and came upon their camp at the mouth of Big Clear creek, only twenty miles from Fort Donnally. Not knowing whether the Indians had attacked the settlement, one of them climbed a pine tree to ascertain from their movements something of their intentions. The Indians were preparing for a massacre.

Prior and Hammond immediately started for the settlement to warn the people of their danger.

The following men, with their families, were in the fort at the time of the attack:
Colonel Andrew Donnally,
Captain Jack Williams,
Richard Williams,
William Blake,
William Hughart,
______ Hughart, Sr.,
John McFerrin,
William McCoy, Sr.,
William McCoy, Jr.,
Henry Hedrick,
James Jordon,
Thomas George,
William Hamilton,
James Graham,
William Strickland,
Griffin,
Philip Hammond,
John Pryor,
Dick Pointer (colored),
William Pritchart.

Alexander Ocheltree and James Burns were killed as they approached the fort.
The loss on the part of the whites was four men killed and two wounded-Pritchart at the tan trough Alexander Ocheltree and James Burns, who were on their way to the fort, and James Graham within the Port William Blake was wounded in the head and Willam Hamilton in the finger. Burns fell dead when shot. Ocheltree ran about three hundred yards, and fell pierced by seven bullets.

The fort was a single log-house, two stories high, and a kitchen one a half stories high, with a passageway of eight feet between them. The stockade was eight feet in height, made of split logs. The fort stood on the east side of Rader's creek, ten miles northwest from Lewisburg.
Dick Pointer was granted his freedom for his work on the day of the battle. John Davis gave him a life lease to a piece of land, on which the people built him a cabin. There Dick eked out a kind of life, and at his death they buried him with the honors of war in Lewisburg cemetery-fulfilling the saying "Man's good deeds are never known through life, but they live after death."

Dick was a large, powerful man, very black, and in the latter part of his life became very dissipated. No monument marks his resting-place, but one should be erected over the grave of him who saved more than seventy human beings-most of them women and children-from the tomahawk and scalping-knife of the savage.

A remarkable incident of the day was the birth of a male child, who grew to manhood, and, from his great size, was known far and wide as Big Joe Hughart.
