They did not know Stewart, though. As soon as the darkness of the winter night came, and the tide began to lift the ship out of the mud, he sent pilots ahead to buoy the channel with lights. The ship, helped somewhat by the wind, but towed by the boats, would go a mile or two up to the nearest buoy, when that light would be put out, and she would be headed for the next one. So quietly was this done that the British never suspected what was going on. But when daylight came there was no Constellation to be seen; she was safe in the Elizabeth River. 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?"
