Archibald Lochry was a Pennsylvania militia leader in the American Revolution.
During the American Revolution, tensions grew between the Americans and American Indians of the Ohio region because of military expeditions such as Colonel Daniel Brodhead's attack on Coshocton in 1781. In the same year, Colonel Archibald Lochry and 107 militiamen under his authority were attacked by American Indians as they were traveling down the Ohio River to join George Rogers Clark in an expedition to take Fort Detroit from the British. Thirty-seven of Lochry's men were killed in the attack and the rest were captured, some later dying violently at the hands of their captors. The survivors were held as prisoners of war in Canada and were not released until 1783.
