The capture of this American frigate by the British frigate Shannon of equal force, was variously related. From all that I could gather, she was not judiciously brought into action, nor well fought after Capt. Lawrence fell. It is too much like the British to hunt up every possible excuse for a defeat; but we must conclude, and I have since found it a general opinion in the United States, that the frigate was by no means in a condition to go into action. The captain was a stranger to his own crew; his ship was lumbered up with her cables and every thing else. She ought to have cruised three or four days before she met the Shannon, and that, it seems, was the opinion of the brave captain of the British frigate; who was every way prepared for the action. The rapid destruction of the British sloop of war Peacock, gave Lawrence high reputation; and he felt as if he must act up to his high character. He seemed like an hero impelled, by high ideas of chivalry, to fight, conquer or die, without attending to the needful cautions and preparations. His first officer he left sick on shore, who died a few days after the battle; his next officer was soon killed; soon after which he fell himself, uttering the never to be forgotten words, "DON'T GIVE UP THE SHIP," which has since become a sort of national motto. While the British captain prudently dressed himself in a short jacket and round hat, so as not to distinguish himself from the other officers, our Capt. Lawrence, who was six feet and upwards tall, was in his uniform and military hat, a fair and inviting mark for the enemy's sharp shooters. No one doubted his bravery, but some have called his prudence in question. This heroic man and his Lieutenant, _Ludlow_, were three times buried with great military pomp; first at Halifax--then at Salem, and last of all at New-York. The name of Lawrence is consecrated in America, while his ever unlucky ship is doomed to everlasting ignominy; for this was the vessel that preferred allowing the British ship Leopard _to muster her crew_, instead of sinking, with her colors flying. In the month of August, Halifax was alarmed, or pretended to be alarmed, by a rumor that the prisoners on Melville Island, which is about three miles, or less, from the town, meditated a sally, with the determination of seizing the capital of Nova Scotia. They immediately took the most serious precautions, and screwed up their municipal regulations to the highest pitch. All the loyal citizens entrusted with arms, were ordered to keep themselves in readiness to march at a minute's warning to repel the meditated attack of about a thousand unarmed Yankees, rendered formidable by a reinforcement of a few dozen half starved soldiers, who were taken by the Indians and British, and sent from Quebec down the river St. Lawrence to the formidable American post on Melville Island, under the command of turnkey Grant! who was himself under the command of Lieut. General Mr. Agent Miller!
