Between 400 and 500 St. Francis  and Mi'kmaq Indians attacked Arrowsic, Maine on September 10, 1722, in conjunction with Father Rale at Norridgewock. Captain Penhallow discharged musketry from a small guard, wounding three of the Indians and killing another. This defense gave the inhabitants of the village time to retreat into the fort, leaving the Indians in full possession of the village. They slaughtered 50 head of cattle and set fire to 26 houses outside the fort, then assaulted the fort, killing one New Englander but otherwise making little impression. That night, Col. Walton and Capt. Harman arrived with 30 men, to which were added approximately 40 men from the fort under Captains Penhallow and Temple. The combined force of 70 men attacked the Indians, but they were overwhelmed by their numbers. The New Englanders then retreated back into the fort.
