But, though worsted in this attack upon Fort Mifflin, the British did not wholly abandon their designs upon it. Immediately upon their repulse, they began their preparations for a second attack. This time they did not propose to rely upon men-of-war alone. Batteries were built upon every point of land within range of Fort Mifflin. Floating batteries were built, and towed into position. By the 10th of November all was ready, and upon that day a tremendous cannonade was opened upon the American works. After two days of ceaseless bombardment, the garrison of the fort was forced to surrender. Since the fall of Fort Mifflin gave the control of the Delaware to the British, the Americans immediately put the torch to the "Andrea Doria" fourteen, the "Wasp" eight, and the "Hornet" ten; while the galleys skulked away along the Jersey coast, in search of places of retreat.

While the Yankee tars on river and harbor duty were thus getting their share of fighting, there was plenty of daring work being done on the high seas. One of the most important cruises of the year was that of the "Raleigh" and the "Alfred." The "Raleigh" was one of the twelve-pounder frigates built under the naval Act of 1775. With her consort the "Alfred," she left the American coast in the summer of 1777, bound for France, in search of naval stores that were there awaiting transportation to the United States. Both vessels were short-handed.

On the 2d of September the two vessels overhauled and captured the snow "Nancy," from England, bound for the West Indies. Her captain reported that he had sailed from the West Indies with a fleet of sixty merchantmen, under the convoy of four small men-of-war, the "Camel," the "Druid," the "Weasel," and the "Grasshopper." The poor sailing qualities of the "Nancy" had forced her to drop behind, and the fleet was then about a day in advance of her.

Crowding on all canvas, the two American ships set out in hot pursuit. From the captain of the "Nancy" Capt. Thompson of the "Raleigh" had obtained all the signals in use in the fleet of Indiamen. The next morning the fleet was made out; and the "Raleigh" and the "Alfred" exchanged signals, as though they were part of the convoy. They hung about the outskirts of the fleet until dark, planning, when the night should fall, to make a dash into the enemy's midst, and cut out the chief armed vessel.

But at nightfall the wind changed, so that the plan of the Americans was defeated. At daylight, however, the wind veered round and freshened, so that the "Raleigh," crowding on more sail, was soon in the very centre of the enemy's fleet. The "Alfred," unfortunately, being unable to carry so great a spread of canvas, was left behind; and the "Raleigh" remained to carry out alone her daring adventure.

The "Raleigh" boldly steered straight into the midst of the British merchantmen, exchanging signals with some, and hailing others. Her ports were lowered, and her guns on deck housed, so that there appeared about her nothing to indicate her true character. Having cruised about amid the merchantmen, she drew up alongside the nearest man-of-war, and when within pistol-shot, suddenly ran up her flag, threw open her ports, and commanded the enemy to strike.

All was confusion on board the British vessel. Her officers had never for a moment suspected the "Raleigh" of being other than one of their own fleet. While they stood aghast, not even keeping the vessel on her course, the "Raleigh" poured in a broadside. The British responded faintly with a few guns. Deliberately the Americans let fly another broadside, which did great execution. The enemy were driven from their guns, but doggedly refused to strike, holding out, doubtless, in the hope that the cannonade might draw to their assistance some of the other armed ships accompanying the fleet.

While the unequal combat was raging, a heavy squall came rushing over the water. The driving sheets of rain shut in the combatants, and only by the thunders of the cannonade could the other vessels tell that a battle was being fought in their midst.

When the squall had passed by, the affrighted merchantmen were seen scudding in every direction, like a school of flying-fish into whose midst some rapacious shark or dolphin has intruded himself. But the three men-of-war, with several armed West-Indiamen in their wake, were fast bearing down upon the combatants, with the obvious intention of rescuing their comrade, and punishing the audacious Yankee.

The odds against Thompson were too great; and after staying by his adversary until the last possible moment, and pouring broadside after broadside into her, he abandoned the fight and rejoined the "Alfred." The two ships hung on the flanks of the fleet for some days, in the hopes of enticing two of the men-of-war out to join in battle. But all was to no avail, and the Americans were forced to content themselves with the scant glory won in the incomplete action of the "Raleigh." Her adversary proved to be the "Druid," twenty, which suffered severely from the "Raleigh's" repeated broadsides, having six killed, and twenty-six wounded; of the wounded, five died immediately after the battle.
