The Siege of Fort Henry was an attack on American militiamen during the American Revolutionary War near the Virginia outpost known as Fort Henry by a mixed band of Indians in September 1777. The fort, named for Virginia Governor Patrick Henry, was at first defended by only a small number of militia, as rumors of the Indian attack had moved faster than the Indians, and a number of militia companies had left the fort. The American settlers were successful in repulsing the Indian attack.
In the summer of 1777, rumors began circulating throughout frontier areas of Virginia and Pennsylvania that Indians living in the Ohio Country were planning attacks on frontier settlements on and around the Ohio River. Fort Henry, which had been constructed in 1774 to protect the settlers in the area around what is now Wheeling, West Virginia, was one of the rumored targets. In early August, General Edward Hand, the commander at nearby Fort Pitt warned Lieutenant David Shepherd and all of the local militia captains of the threat, ordering them to gather at Fort Henry. For a time thereafter, militia companies stayed at Fort Henry, improving its defenses and patrolling for Indians. However, the absence of any obvious threat led many of those companies to leave and return to their homes. By the end of August, only two companies, those of Joseph Ogle and Samuel Mason, remained.
The battle is reported in some sources to have taken place on September 1, and in others on September 21.
On the night of the battle, a mixed band of about 200 Indians (predominantly Wyandot and Mingo, although there were also some Shawnee and Delaware) under the leadership of the Wendat chief Pomoacan, approached the fort in great stealth and secrecy. Local men later joined by recruits from Fort Shepherd (in Elm Grove) and Fort Holliday defended the fort. When four men left the fort early that morning, the Indians attacked them, killing one. The other three escaped, including two who returned to the fort to raise the alarm.
