It was just at New Year's, in 1778, that Barney arrived in Baltimore; and as the frigate of which he was to be the first lieutenant was not yet ready for sea, he took command of a pilot-boat to cruise about the bay and watch the movements of the enemy, who had then several ships in the Chesapeake. One night, as he was returning from a reconnoissance, he found a merchant-sloop from Baltimore on her way down the bay, and hailed her, telling her what dangers she would meet below. To his no small surprise he was answered by a volley of musketry. He tacked in order that he might the better return this unlooked-for fire, and presently discovered on the off side of the sloop a ship's barge lashed alongside. It was now clear why his seeming friend had fired on him. The enemy had cut out the sloop, and they were using her as a decoy to capture Barney. But he served them the same turn that he had served the "Racehorse;" for after a short and sharp struggle he captured them and took them to the city. The barge belonged to His Majesty's ship "Otter;" and Barney, mindful of the treatment he had received on board the "Perseus," took the best of care of his prisoners,--above all of Gray, the officer in charge, who had been wounded, and sent a flag-of-truce boat to the "Otter," to bring them what they needed. On the last day of March the "Virginia" left Baltimore, and attempted under cover of the night to pass the British lookouts in the bay, and so get out to sea. No doubt she would have done it safely had not the pilot, losing his way, run her ashore on the Middle Ground, a large shoal in the lower Chesapeake. The morning broke, and found her hard and fast aground, with three of the enemy's frigates close at hand. Nicholson, the captain of the "Virginia," now called away his barge and left the ship, making his escape to land. It is a story that one must grieve to tell of an American officer; but it can only be supposed that, having but just entered the navy, he did not know what honor and duty meant. There was nothing left now but surrender, for the rest could not escape. Barney was now a prisoner on board the "Emerald" frigate. It is clear that even in a bitter war not only one good turn deserves another, but secures another; for the kind treatment which Barney had received from Captain Elphinstone resulted in his kindness to the "Otter's" men, and this again, which was well known throughout the British squadron, gained for him equal favors in his new captivity. But this did not last long; for after a little while he was sent to New York, where for the first time he came to know the horrors of a prison-ship.
