The first day all hands were roused from their sleep in the boat and mustered at two p.m.; their arms being examined, they were ordered to remain at the boat in readiness for any emergency, while the officers and two artillerymen relieved the look-out at the battery. Twenty-eight embrasures, with heavy guns in them, were counted in the enemy's forts; and so close were the party, that with pocket-telescopes they could clearly distinguish the faces of the people, and observed General Moncellia, the brother-in-law of Rosas, drive up in his carriage with four horses, and, dismounting, inspect the troops and guns. Little did he suspect the foe he had near him. Having remained some time, the officers crawled back to the boats to take some rest, but they were far too anxious to sleep long; and the next night was passed, as before, in paying constant visits to the rocket-battery. Once they were nearly discovered, by one of the men incautiously exposing himself. As Lieutenant Mackinnon was watching the battery, he observed the sentry suddenly stop, and eye the spot narrowly. "Hold fast," he whispered to the man; "don't move, as you value your life." The man obeyed, and, to the lieutenant's infinite relief, he at last saw the sentry move on. Daybreak of the 4th came at length; the wind blew fairly down the stream, and everyone was on the tiptoe of expectation, listening for the report of two guns, the preconcerted signal of the fleet being about to sail. It was a time of the greatest anxiety, for any moment, if discovered, the twenty-eight pieces of ordnance might have commenced playing on them, and blown them all to atoms; but fortunately the eyes of the enemy were turned up the stream, towards the point from whence the fleet was expected to appear. Slowly the hours seemed to pass, till at length, at nine a.m., the welcome sound of the two guns came booming along the water; and immediately the men proceeded from the boat to the rocket-stands, creeping along like a band of North American Indians on a war expedition to surprise a sleeping foe. A long pole, with the British flag made fast to it, had been prepared, on the elevation of which the first discharge of rockets was to take place. The squadron of men-of-war and merchantmen now approached, the _Gorgon, Fulton_, and _Alecto_ leading. Majestically they glided on till they came within range of the batteries, at which they commenced firing their shells with admirable precision. The long and anxious moment at length arrived for the discharge of the rockets. Lieutenant Mackinnon waved his cap aloft; at this signal Lieutenant Barnard planted the British flag under the nose of the enemy, and, taking off his cap, made them a low bow.
