In the address of the House of Assembly of Upper Canada,[45] in answer to the President's speech at the opening of the Provincial Parliament, 27th February, 1813, they say, "We learn, with the highest satisfaction, that the most vigorous measures have been adopted under the direction of the Commander of the forces, and are now in operation, to strengthen the Provincial Marine, and preserve the superiority of the Lakes so essential to the prosperity of this Province." The same expressions occur in the address of the Legislative Council, and in March following, on Sir George Prevost's arrival in Upper Canada, the House of Assembly and town of York addressed him in similar terms. The campaign of 1813 opened, on the part of the Americans, with the attack and capture of York. The squadron under Commander Chauncey employed on this expedition, after landing part of the force at the Niagara frontier, returned to Sackett's Harbour, from whence it again sailed towards the end of May, with another strong force collected from that place and its neighbourhood, for the purpose of uniting with the troops on the Niagara frontier, in an attack upon Fort George. In this attack, which took place on the 27th May, the overwhelming numbers of the enemy prevailed, and the small but gallant band of about 1,500 men, under Brigadier-General Vincent, which had, for more than two hours, opposed nearly 5,000 of the Americans, after evacuating Fort George, spiking the guns, and destroying the ammunition, retreated towards the head of the Lake, General Vincent having first called in all the detachments from the different Posts on that frontier.
