A class of armed vessels outside the limits of the regular navy, but very active and efficient in the service of the country, was the maritime forces of the individual states. Before Congress had seen the necessity for a naval force, several of the colonies had been alive to the situation, and fitted out cruisers of their own. Even after the Revolution had developed into a war of the first magnitude, and after the colonies had assumed the title of states, and delegated to Congress the duty of providing for the common defence, they still continued to fit out their own men-of-war to protect their ports and act as convoys for their merchant fleets. Though vessels in this service seldom cruised far from the coast of their home colony, yet occasionally they met the vessels of the enemy, and many sharp actions were fought by them.

Of all the actions fought by the State cruisers, the most hotly contested was that between the Pennsylvania cruiser "Hyder Ali," and the British sloop-of-war "Gen. Monk." The "Hyder Ali" was a merchantman, bought by the state just as she was about departing on a voyage to the West Indies. She was in no way calculated for a man-of-war; but the need was pressing, and she was pierced for eight ports on a side, and provided with a battery of six-pounders. The command of this vessel was given to Joshua Barney, a young officer with an extensive experience of Yankee privateers and British prisons, and whose later exploits in the United States navy are familiar to readers of "Blue-Jackets of 1812."

Barney's instructions were, not to go to sea, but to patrol the Delaware River and Bay, and see that no privateer lay in wait for the merchant-vessels that cleared from the port of Philadelphia. In April, 1782, the "Hyder Ali" stood down Delaware Bay at the head of a large fleet of outward-bound merchantmen. When Cape May was reached, strong head-winds sprang up, and the whole fleet anchored to await more favorable weather before putting out to sea. While they lay at anchor, the "Hyder Ali" sighted a trio of British vessels, two ships and a brig, rounding the cape. Instantly Barney signalled his convoy to trip anchor and retreat, a signal which was promptly obeyed by all save one too daring craft, that tried to slip round the cape, and get to sea, but fell into the hands of the enemy. Soon the whole fleet, with the "Hyder Ali" bringing up the rear, fled up the bay. The British followed in hot pursuit.

At a point half-way up the bay the pursuers parted; one of the ships, a frigate, cutting through a side channel in the hope of intercepting the fugitives. The other two pursuers, a privateer brig and a sloop-of-war, continued in the wake of the "Hyder Ali." The brig proved herself a clipper, and soon came up with the American vessel, which promptly offered battle. The challenge was declined by the privateer, which fired a harmless broadside, and continued on up the bay. Barney let her pass, for he had determined to risk the dangers of an unequal combat with the sloop-of-war. This vessel came up rapidly; and as she drew near Barney luffed up suddenly, and let fly a broadside. This somewhat staggered the enemy, who had expected only a tame surrender; but she quickly recovered, and came boldly on. At this juncture Barney turned to his helmsman, and said,—

"Now, when I give the word, pay no attention to my order, but put the helm hard-a-starboard. Pay no heed to the actual command I may give you."

The British vessel was then within half pistol-shot, and her forward guns were beginning to bear. From his station on the quarter-deck Barney shouted to his steersman in stentorian tones,—

"Port your helm. Hard-a-port."

The order was clearly heard on board the enemy, and he prepared to manœuvre his ship accordingly. But the steersman of the "Hyder Ali" remembered his instructions; and before the enemy discovered the ruse, the American ship lay athwart the other's bow, and the bowsprit of the enemy was caught in the "Hyder Ali's" rigging, giving the latter a raking position. Quickly the Yankee gunners seized the opportunity. Not five miles away was a British frigate ready to rush to the assistance of her consort, and whatever was to be done by the bold lads of Pennsylvania had to be done with expedition. No cheer rose from their ranks; but with grim determination they worked at the great guns, pouring in rapid and effective broadsides. The explosions of the two batteries were like the deafening peals of thunder echoed and re-echoed in some mountain-gorge. Smoke hid the vessels from sight, and the riflemen in the tops could only occasionally catch sight of the figures of the enemy. The enemy had twenty guns to Barney's sixteen; but he was out-manœuvred at the start, and this disadvantage he never overcame. Half an hour from the time of the opening of the battle, his flag was struck, and the Americans, with lusty cheers, took possession of their prize. There was no time for ceremony. The frigate had seen the conflict from afar, and was bearing down upon the two antagonists. So without even asking the name of the captured vessel, Barney hastily threw a prize crew aboard, ordered her to proceed to Philadelphia, and himself remained behind to cover the retreat.

Some hours later, having escaped the British frigate, the two vessels sailed up to a Philadelphia wharf. The scars of battle had been in no way healed: the tattered sails, the shattered hulls and bulwarks, the cordage hanging loosely from the masts, told the story of battle. The crowd that rushed to the wharf, and peered curiously about the decks of the two vessels, saw a ghastly and horrible sight. For the battle had been as sanguinary as it was spirited, and the dead still lay where they fell. On the British vessel, the "Gen. Monk," lay the lifeless bodies of twenty men; while twenty-six wounded, whose blood stained the deck, lay groaning in the cock-pit below. On the "Hyder Ali" were four killed and eleven wounded.

This action, for steadiness and brilliancy, was not surpassed by any naval duel of the war of the Revolution. By it the name of Joshua Barney was put upon a plane with those of the most eminent commanders in the regular navy; and had not the war speedily terminated, he would have been granted a commission and a ship by the United States.
