From Ohio History Central
David Williamson was a militia officer and public official in the Ohio Country in the years of the American Revolution and the early nation.
Williamson was born in Carlisle, Pennsylvania in 1752. While he was still a child, Williamson's family moved to western Pennsylvania and eventually settled in Washington County.
By the age of twenty-five, Williamson had attained the rank of captain in the Washington County militia. His men probably fought in the Battle of Point Pleasant and in other engagements in Lord Dunmore's War in 1774. By the age of thirty, Williamson had become a lieutenant colonel in the Pennsylvania militia.
During the American Revolution, Williamson and his militia played an active role in the Ohio Country. Throughout the war, many Native Americans were loyal to the British or feared the increasing number of white Americans moving into the Ohio Country. The natives ambushed, killed, and kidnapped numerous settlers. Many colonial settlers on the frontier believed that Christian Delaware Indians living in Schoenbrunn, Lichtenau, and Gnadenhutten were responsible for some of the attacks. Actually these natives and the Moravian missionaries who lived and worked with them were not involved in the violence, The Christian Delawares and the missionaries, including David Zeisberger and John Heckewelder, had tried to remain neutral in the conflict.
In 1781, Williamson led two companies of Pennsylvania militia into eastern Ohio to ascertain the true leanings of the Christian Delawares. Williamson captured several natives and took them to Fort Pitt. The Americans quickly released the prisoners after the militiamen could not place any blame on them for the Native American attacks.
Williamson's distrust and dislike of the Native Americans continued to grow as more attacks occurred against white settlers. In March 1782, Williamson led a detachment of Pennsylvania militia to the Moravian mission at Gnadenhutten. The Moravians and their charges had abandoned the village the year before, but approximately one hundred natives had returned to harvest any remaining crops in the fields. The militiamen captured the Christian Delawares and decided incorrectly that they were responsible for the attacks. The soldiers killed ninety-six men, women, and children at Gnadenhutten. This event became known as the Gnadenhutten Massacre.
Williamson's militia continued in service for the remainder of the Revolutionary War. He and his men accompanied Colonel William Crawford to the Ohio Country in May and June 1782. Their intentions were to destroy the villages of the Wyandot Indians, the Munsee Indians and the Delaware Indians along the Sandusky River. With the assistance of British soldiers, the Indians defeated the militiamen in the Battle of the Sandusky and the Battle of the Olentangy on June 4–6, 1782. Of the 480 Pennsylvanians involved in the battle, approximately seventy men were killed or captured including Crawford. Williamson and others led the survivors back to the relative safety of Pennsylvania.
Following the war, Williamson was elected as the Washington County sheriff. He invested much of his money in various business ventures. Many of the enterprises failed. David Williamson died in poverty in 1814.
