The right bank of Otter Creek at its mouth is a rock-ribbed promontory, connected with the mainland, except at high water, by a narrow neck of low, alluvial soil. On the lakeward side of the point earthworks were thrown up, and mounted with several pieces of artillery, for the defense of the entrance against an expected attempt of the enemy to destroy the American fleet. The militia of Addison, Chittenden, and Franklin counties were put in readiness to turn out on the firing of signal guns, and a small detachment was posted at Hawley's Farm, near the mouth of Little Otter, to watch the approach of the army. About 1,000 of the militia were stationed at Vergennes. All the night of the 13th the officers of the neighboring towns were running bullets at their treasurer's, where powder and lead were stored for the militia at Vergennes. On the 10th of May the British squadron passed Cumberland Head, and on the 14th eight of the galleys and a bomb-ketch appeared off the mouth of Great Otter, while a brig, four sloops, and several galleys were two miles to the northward. The galleys opened a fire on the battery, which was bravely defended by Captain Thornton of the artillery and Lieutenant Cassin of the navy. The rapid discharge of the guns, repeated in echoes from the rugged steeps of Split Rock Mountain till it became a continuous roar, for a time greatly alarmed the inhabitants of the adjacent country, but the assailants were beaten off after receiving considerable injury, while they inflicted on the defenders only the dismounting of one gun, and the slight wounding of two men. The British fleet sailed northward, and next day Macdonough's flotilla issued forth ready for battle, and sailed northward to Cumberland Bay. The importance of this action has not had proper recognition. It is briefly, if at all, mentioned by historians. If the defense of the little battery which now bears the name of Fort Cassin, in honor of Macdonough's brave lieutenant, had been less gallant and successful, our fleet would in all probability have been destroyed before it could strike the blow which gained its commander imperishable renown. The British keenly felt the lost opportunity, for Captain Pring was charged by his superiors with cowardice and disobedience of orders in not having taken the battery and blockaded the American squadron. The invasion of Canada again was the plan of the campaign for 1814. The two western armies were to move against the enemy on the upper lakes and at the Niagara frontier, while General Izard was to cut the communication on the St. Lawrence between Kingston and Montreal. The Vermonters of the 30th and 31st regiments, and part of the 11th, with the militia and volunteers raised in the vicinity of Lake Champlain were employed in this army, while the remainder of the 11th were in service on the Niagara frontier.
