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 three armed American schooners anchored off the fort. Captain Alexander Dobbs, R.N., embarked with 70 seamen and marines in six bateaux 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.
