The Great Cove massacre was an attack by Shawnee and Lenape warriors led by Shingas, on the community of Great Cove, Pennsylvania (sometimes referred to as Big Cove, modern day McConnellsburg, Pennsylvania in what was, at the time, Cumberland County) on 1 November 1755, in which about 50 settlers were killed or captured. Following the attack, settlers returned to the community to rebuild, and the Provincial Council of Pennsylvania began constructing a chain of forts and blockhouses to protect settlers and fend off further raids. These forts provided an important defense during the French and Indian War.
