French and Indian War: Kittanning Expedition.

The Kittanning Expedition, also known as the Armstrong Expedition or the Battle of Kittanning, was a raid during the French and Indian War that led to the destruction of the American Indian village of Kittanning, which had served as a staging point for attacks by Lenape warriors against colonists in the British Province of Pennsylvania. Commanded by Lieutenant Colonel John Armstrong Sr., this raid deep into hostile territory was the only major expedition carried out by Pennsylvanian provincial troops during a brutal backcountry war. Early on September 8, 1756, they launched a surprise attack on the Indian village.
