Previous to the 10th of April, the steam frigate Powhatan and the transports Atlantic and Illinois had sailed from New York with troops, ordnance and provisions, for Fort Pickens; but before their arrival at that place, a bearer of dispatches from Washington reached the commander of the naval forces in the bay, with instructions to reinforce the fort. Between the hours of 11 and 12 o’clock on Friday night, April 12th, this was accomplished without bloodshed. “As soon as it became dark,” said an officer on board the sloop-of-war Brooklyn, one of the blockading fleet, “we began work with good will and in earnest. At first the marines from the frigate Sabine and the sloop St. Louis, came on board our vessel, and immediately after the accomplishment of this, the anchor was hoisted by the jolly old salts, with the merry chant of— ‘General Jackson won the day, Heave, yeo ho! At New Orleans, the people say Yeo, heave yeo!’ We ran as close to the shore as possible, came to anchor, and without a moment’s delay, lowered the boats and filled them with troops. “At 11 o’clock, Lieutenant Albert N. Smith, of Massachusetts, being in command, they started on their mission, uncertain if they would live to see the light of another day. As they left the side of the vessel, many a ‘God cause you to succeed,’ came from the lips of the loyal men at my side. If I live a thousand years I shall never forget the feelings I experienced when I saw those brave fellows shake hands with their old comrades. A tear would now and then glisten in the gloom, but be instantly wiped away with a clenched hand. These men knew their danger, and with the knowledge, dared to face it with a courage eminently worthy of praise—and may they receive it! “The party were instructed to send up signals should they be attacked, and I do assure you never were keener eyes than ours on that eventful night, as we pierced into the darkness, momentarily expecting to see a rocket light up the midnight gloom; but none appeared. While we were thus anxiously awaiting some evidence of the success or non-success of their mission, a boat was hailed. A faint answer comes back: ‘Lieutenant Smith and the boat’s crew!’ and in whispers we hear the news, ‘they have been successful!’ Brother officers shake hands, and give Lieutenant Smith that praise justly deserved by him. They went around inside of the harbor, passed under the guns of Forts McRae and Barrancas without being heard, and safely landed all the troops without molestation.
