As yet the armies of the United States were not organized, and for some time Captain George Rose was at a loss what to do with his volunteers. They were riflemen, ready for any detached service to which they might be assigned. The militia forces raised were, of course, to serve in their own respective States; but the volunteers were allowed to attach to any regiment they chose. For some time, it was doubtful whether Captain Rose would be sent West under Hull and Harrison, or to the North to act under General Jacob Brown. The latter course was at last decided upon, and they hurried to the northern frontier of New York. But small preparations had been made for the defence of this portion of the frontier. From Oswego to Lake St. Francis, an expansion of the St. Lawrence, General Brown's forces were scattered. The length of this territory was about two hundred miles. There was only one American war-vessel (the _Oneida_) on Lake Ontario. This was commanded by Lieutenant Melancthon Woolsey; while the British, in anticipation of difficulties, had built at Kingston, at the foot of the lake, a small squadron of light vessels-of-war. Brown and Woolsey were authorized to defend the frontier from invasion, but not to act on the offensive except in certain emergencies. About the 20th of July, Fernando's company joined the regiment of Colonel Bellinger at Sackett's Harbor, at the eastern end of Lake Ontario. Nine days later, the British squadron composed of the _Royal George_, 24 guns, _Prince Regent_, 22 guns, _Earl of Moira_, 20 guns, _Simcoe_, 12 guns, and _Seneca_, 4 guns, appeared and bore down on the American forces there. Fernando was sleeping when the discovery was made, but was soon roused and saw soldiers hauling in the _Oneida_ so as to lay her broadside to the approaching enemy. Colonel Bellinger's militia were many of them raw recruits, and the approach of a fleet unnerved a few of them; but the majority were cool as veterans. "Take that thirty-two pound gun up on the bluff," commanded the colonel, pointing out an old iron cannon down by the shore. Fernando assisted them to drag it to the rocky bluff, and the whole battery was placed in charge of Captain Vaughn, a sailing master in the navy. Slowly the fleet bore in, the _Royal George_, having the heaviest guns, coming ahead of the others. A wreath of smoke curled up from her forecastle, and a ball, skipping over the water, struck the sandy beach. Captain Rose and his company of riflemen took up their station on the high bluff, where, should the troops attempt to land, they might do effective work. Fernando had been promoted to sergeant in the company and was quite popular with both officers and men.
