After it had become apparent that the Americans had the command of Lake Ontario, and could visit to burn and destroy every village or unfortified town, held by the British, some slight and very inadequate exertion was made to remedy so distressing a state of affairs. In May, Sir James L. Yeo, with several other naval officers and 450 seamen arrived at Quebec, _en route_ for the lakes. Captains Barclay, Pring, and Finnis, had been some time at Kingston, and were doing something in the way of preparing for service the few, vessels at Kingston, by courtesy called a fleet. Sir George Prevost and Sir James L. Yeo lost little time in reaching Kingston together. The American fleet was off Niagara, bombarding Fort George. It occurred to the two commanders that an attack upon their naval station at Sackett's Harbour would not be amiss, and it was resolved upon. About a thousand men were embarked on board of the _Wolfe_, of 24 guns, the _Royal George_, of 24 guns, the _Earl of Moira_, of 18 guns, and four armed schooners, each carrying from ten to twelve guns, with a number of batteaux. The weather was very fine. Everything was got in readiness for an expeditious landing. The soldiers were transferred from the armed vessels to the batteaux, so that no time might be lost in the debarkation. Two gun-boats were placed in readiness, as a landing escort, The boats were under the direction of Captain Mulcaster, of the Royal Navy, and the landing under the immediate supervision of Sir George Prevost and Sir James L. Yeo. It was expected that, in the absence of the American fleet and army, the growing and formidable naval establishment of the enemy would be temporarily rendered worthless. And the expectation was not an unnatural one. It was, indeed, in a trifling degree, realised. There was some injury done to Sackett's Harbor, but not of such a nature as to produce a strong effect upon either Canadian minds or American nerves. A number of boats, containing troops, from Oswego, were dispersed, while doubling Stoney Point, and twelve of them, with 150 men on board, captured. But the loss to the British was the delay caused by such an unlucky acquisition. The landing was deferred by it. General Brown was put on the alert. He had time to make arrangements and to collect troops. He planted 500 militia on the peninsula of Horse Island, which is a sort of protection wall for the harbour. He ordered them to be still and close, keep their powder dry, and reserve their fire. And they did their best, in accordance with these instructions, until the fleet opened a heavy cannonade to cover the landing of the invaders, when General Brown's militiamen quaked exceedingly. When the troops had landed, and the American militia had lost, by death, their immediate commander, Colonel Mills, they fled with the utmost precipitation. But it was the conduct of these very cowards that afterwards alarmed, the ever suspicious Sir George Prevost, and caused,
