The British determined to blockade her there, and succeeded in doing so; but although they made several desperate attempts to carry her by boarding, they never succeeded. Stewart had her so well guarded with boats, and the boats with a circle of booms, while the ship was protected with boarding netting, her guns kept double-shotted, and her officers and crew always on the alert, that her enemies themselves were forced to admire the care taken of her. It was the joke among the British officers that Stewart must be a Scotchman, he was so wary and so watchful with his ship; and the British Admiral is said to have remarked: "If that had been a French ship, we would have had her long ago."

Having satisfied himself that although the Constellation could not be taken, yet it was unlikely that she would get out during the war, Stewart applied for and got the Constitution. This was in 1814. The Constitution had then made her celebrated escape from Admiral Broke's squadron, and had destroyed the Guerrière and the Java,—for when "Old Ironsides" got through with an enemy, he was generally past saving. It may be imagined with what splendid hopes Stewart took the great ship after she had been refitted at Boston. He got out, although seven British ships blockaded Boston, and sailed to the West Indies. He made a few prizes, and took a small British cruiser; but this was not enough for the Constitution to do. Stewart's disappointment with his cruise was great, and it almost seemed as if the ship were no longer to be a favorite of fortune, until she was chased by two frigates, the Junon and the Tenedos, off the Massachusetts coast. Stewart had a good pilot aboard, and he made for Marblehead under a spanking breeze, with the two British frigates legging it briskly after him. The Constitution drew about twenty-two feet of water, and Stewart could not conceal his anxiety as the pilot carried her along the dangerous coast, and it seemed as if any moment she might be put on the rocks. The pilot, though, a cool-headed, steady fellow, knew his business, and was nettled at Stewart's evident uneasiness. The British ships, not knowing the coast, declined to follow, and were falling slightly astern; but it looked as if the Constitution would only escape one danger to be destroyed by another. Presently Stewart asked the pilot for the hundredth time,—

"How many feet of water has she under her keel now, pilot?"

"Two," answered the pilot; when, seeing Stewart's countenance turn pale with apprehension, he added nonchalantly: "And afore long she won't have but one!"

The effect of this news upon the captain of a war-ship may be imagined; but in a moment or two the ship slipped into deep water, and, carrying sail hard, got into Marblehead safe and sound, while cheering multitudes flocked to the shore to welcome her.

In a few days Stewart succeeded in slipping into Boston again,—the sixth time in the course of the war that the ship had eluded the British blockade. Stewart took up his berth in the upper harbor, and as he was known to be a fighting captain with a fighting ship, the State and city authorities concluded that they would rather have him a little farther off. Accordingly they asked him to take his ship down into the lower harbor, as, if the British blockading fleet attacked him where he was, the cannonade would do great damage to the town. Stewart's reply to this request was characteristic. He coolly informed them that he should stay where he was, but it would make very little difference to them where he lay, as, "if attacked, I shall make such a defence as will endanger the town." He recommended them to build some additional batteries to defend the town. The authorities had to be satisfied with this reply; but they took Stewart's advice, and increased their batteries so that they were better prepared than before to meet a bombardment, should the British fleet treat them to one.

On the 17th of December, 1814, Stewart again slipped past the blockading fleet, making the seventh time the Constitution had done this, and sailed on his last and greatest cruise. He had lately been married, and it is said that he asked his wife what he should bring home to her. She replied, "A British frigate." Stewart replied, "I will bring you two of them." He kept his promise.

Stewart was soon on the broad ocean. Nothing of note happened until February, when one morning, off the coast of Portugal, Stewart suddenly and from no reason he was able to give, except an unaccountable impulse to proceed to a certain spot in the Atlantic, changed the ship's course and ran off sixty miles to the southwest. At two o'clock in the afternoon of the 20th of February, 1815, about sixty leagues southwest of the Madeira islands, a small frigate, the Cyane, was sighted, and a little later a large sloop-of-war, the Levant. The Constitution immediately gave chase, although it was thought that one of the ships was much heavier than she really was, as she had double gun-streaks and false ports painted amidships, which the Americans, in chasing, took for real guns and ports.

It soon became plain that the two ships were bent on fighting, but they manœuvred in a very masterly manner for several hours, in order to get together before trying conclusions with the great frigate. At five minutes past six o'clock they hove to and hoisted their ensigns, and the Constitution replied by showing her colors. The three ships were arranged like the points of an equilateral triangle,—a very advantageous position for the two attacking ships, but one which was turned by the superb seamanship of Stewart to his own profit by what is commonly esteemed to have been the finest manœuvring ever known of an American ship in action. Stewart fought his port and starboard batteries alternately, giving one of his antagonists a terrible broadside, then wearing, and letting fly at the other, raking them repeatedly, and handling his ship in such a manner that neither the Levant nor the Cyane ever got in a single raking broadside.
