Almost every day furnished accounts evincing the activity of Commodore Porter, and the officers and men under his command; but for a long time their industry and zeal was rather shown in the suppression of piracy than the punishment of it. At length, however, an opportunity offered for inflicting the latter, as detailed in the following letter, dated Matanzas, July 10, 1823.

“I have the pleasure of informing you of a brilliant achievement obtained against the pirates on the 5th inst. by two barges attached to Commodore Porter’s squadron, the Gallinipper, Lieut. Watson, 18 men, and the Musquito, Lieut. Inman, 10 men. The barges were returning from a cruise to windward; when they were near Jiguapa Bay, 13 leagues to windward of Matanzas, they entered it—it being a rendezvous for pirates. They immediately discovered a large schooner under way, which they supposed to be a Patriot privateer; and as their stores were nearly exhausted, they hoped to obtain some supplies from her. They therefore made sail in pursuit. When they were within cannon shot distance, she rounded to and fired her long gun, at the same time run up the bloody flag, directing her course towards the shore, continuing to fire without effect. When she had got within a short distance of the shore, she came to, with springs on her cable, continuing to fire; and when the barges were within 30 yards, they fired their muskets without touching boat or man; our men gave three cheers, and prepared to board; the pirates, discovering their intention, jumped into the water, when the bargemen, calling on the name of “Allen,” commenced a destructive slaughter, killing them in the water and as they landed. So exasperated were our men, that it was impossible for their officers to restrain them, and many were killed after orders were given to grant quarter. Twenty-seven dead were counted, some sunk, five taken prisoners by the bargemen, and eight taken by a party of Spaniards on shore. The officers calculated that from 30 to 35 were killed. The schooner mounted a long nine pounder on a pivot, and 4 four pounders, with every other necessary armament, and a crew of 50 to 60 men, and ought to have blown the barges to atoms. She was commanded by the notorious Diableto or Little Devil. This statement I have from Lieut. Watson himself, and it is certainly the most decisive operation that has been effected against those murderers, either by the English or American force.

“This affair occurred on the same spot where the brave Allen fell about one year since. The prize was sent to Thompson’s Island.”

A British sloop of war, about the same time, captured a pirate schooner off St. Domingo, with a crew of 60 men. She had 200,000 dollars in specie, and other valuable articles on board. The brig Vestal sent another pirate schooner to New-Providence.

CAPTURE OF A PIRATICAL STATION IN CUBA.

The U. S. schooners of war Greyhound and Beagle left Thompson’s Island, June 7, 1823, under the command of Lieuts. Kearney and Newton, and cruised within the Keys, on the south side of Cuba, as far as Cape Cruz, touching at all the intermediate ports on the island, to intercept pirates. On the 21st July, they came to anchor off Cape Cruz, and Lieut. Kearney went in his boat to reconnoitre the shore, when he was fired on by a party of pirates who were concealed among the bushes. A fire was also opened from several pieces of cannon erected on a hill, a short distance off. The boat returned, and five or six others were manned from the vessels, and pushed off for the shore, but a very heavy cannonade being kept up by the pirates on the heights, as well as from the boats were compelled to retreat. The two schooners were then warped in, when they discharged several broadsides, and covered the landing of the boats. After a short time the pirates retreated to a hill that was well fortified. A small hamlet, in which the pirates resided was set fire to and destroyed. Three guns, one a four pounder, and two large swivels, with several pistols, cutlasses, and eight large boats, were captured. A cave, about 150 feet deep, was discovered, near where the houses were, and after considerable difficulty, a party of seamen got to the bottom, where was found an immense quantity of plunder, consisting of broadcloths, dry goods, female dresses, saddlery, &c. Many human bones were also in the cave, supposed to have been unfortunate persons who were taken and put to death. A great deal of the articles were brought away, and the rest destroyed. About forty pirates escaped to the heights, but many were supposed to have been killed, from the fire of the schooners, as well as from the men who landed. The bushes were so thick that it was impossible to go after them. Several other caves are in the neighbourhood, in which it was conjectured they occasionally take shelter.

PIRATES TAKEN AND EXECUTED.

A piratical vessel, and her crew of thirty-eight men were captured off Matanzas on the 16th May, 1825, by a British cutter and a steamboat fitted out at that place. Several of the pirates were killed, and the rest sent to Havana for trial. It was ascertained that some of them had assisted in capturing more than twenty American vessels, whose crews were MURDERED!!

An additional gang of pirates was hung at the same period, at Porto Rico.—Eleven at once.
