Capture of the Ohio and Somers

On the night of 12 August 1814, as a prelude to a British attack on Fort Erie an expedition was mounted against thee armed American schooners anchored off the fort. Captain Alexander Dobbs R.N. embarked with 70 seaman and marines in six batteaux which had been portaged from Frenchman's Creek, and by a ruse got close enough to cut the hawsers and board and capture the OHIO and SOMERS. The third vessel PORCUPINE escaped. Dobbs' victory was the last naval action fought on the Great Lakes in the War of 1812
