At Grand Jerre, the privateers publicly made sale by auction, of the cargoes of their prizes. From all parts of Lower Louisiana, people resorted to Barrataria, without being at all solicitous to conceal the object of their journey. The most respectable inhabitants of the state, especially those living in the country, were in the habit of purchasing smuggled goods coming from Barrataria.

The government of the United States sent an expedition under Commodore Patterson, to disperse the settlement of marauders at Barrataria; the following is an extract of his letter to the secretary of war.

Sir--I have the honor to inform you that I departed from this city on the 11th June, accompanied by Col. Ross, with a detachment of seventy of the 44th regiment of infantry. On the 12th, reached the schooner Carolina, of Plaquemine, and formed a junction with the gun vessels at the Balize on the 13th, sailed from the southwest pass on the evening of the 15th, and at half past 8 o'clock, A.M. on the 16th, made the Island of Barrataria, and discovered a number of vessels in the harbor, some of which shewed Carthagenian colors. At 2 o'clock, perceived the pirates forming their vessels, ten in number, including prizes, into a line of battle near the entrance of the harbor, and making every preparation to offer me battle. At 10 o'clock, wind light and variable, formed the order of battle with six gun boats and the Sea Horse tender, mounting one six pounder and fifteen men, and a launch mounting one twelve pound carronade; the schooner Carolina, drawing too much water to cross the bar. At half past 10 o'clock, perceived several smokes along the coasts as signals, and at the same time a white flag hoisted on board a schooner at the fort, an American flag at the mainmast head and a Carthagenian flag (under which the pirates cruise) at her topping lift; replied with a white flag at my main; at 11 o'clock, discovered that the pirates had fired two of their best schooners; hauled down my white flag and made the signal for battle; hoisting with a large white flag bearing the words "Pardon for Deserters"; having heard there was a number on shore from the army and navy. At a quarter past 11 o'clock, two gun boats grounded and were passed agreeably to my previous orders, by the other four which entered the harbor, manned by my barge and the boats belonging to the grounded vessels, and proceeded in to my great disappointment. I perceived that the pirates abandoned their vessels, and were flying in all directions. I immediately sent the launch and two barges with small boats in pursuit of them. At meridian, took possession of all their vessels in the harbor consisting of six schooners and one felucca, cruisers, and prizes of the pirates, one brig, a prize, and two armed schooners under the Carthagenian flag, both in the line of battle, with the armed vessels of the pirates, and apparently with an intention to aid them in any resistance they might make against me, as their crews were at quarters, tompions out of their guns, and matches lighted. Col. Ross at the same time landed, and with his command took possession of their establishment on shore, consisting of about forty houses of different sizes, badly constructed, and thatched with palmetto leaves.

When I perceived the enemy forming their vessels into a line of battle I felt confident from their number and very advantageous position, and their number of men, that they would have fought me; their not doing so I regret; for had they, I should have been enabled more effectually to destroy or make prisoners of them and their leaders; but it is a subject of great satisfaction to me, to have effected the object of my enterprise, without the loss of a man.

The enemy had mounted on their vessels twenty pieces of cannon of different calibre; and as I have since learnt, from eight hundred, to one thousand men of all nations and colors.

Early in the morning of the 20th, the Carolina at anchor, about five miles distant, made the signal of a "strange sail in sight to eastward"; immediately after she weighed anchor, and gave chase the strange sail, standing for Grand Terre, with all sail; at half past 8 o'clock, the chase hauled her wind off shore to escape; sent acting Lieut. Spedding with four boats manned and armed to prevent her passing the harbor; at 9 o'clock A.M., the chase fired upon the Carolina, which was returned; each vessel continued firing during the chase, when their long guns could reach. At 10 o'clock, the chase grounded outside of the bar, at which time the Carolina was from the shoalness of the water obliged to haul her wind off shore and give up the chase; opened a fire upon the chase across the island from the gun vessels. At half past 10 o'clock, she hauled down her colors and was taken possession of. She proved to be the armed schooner Gen. Boliver; by grounding she broke both her rudder pintles and made water; took from her her armament, consisting of one long brass eighteen pounder, one long brass six pounder, two twelve pounders, small arms, &c., and twenty-one packages of dry goods. On the afternoon of the 23d, got underway with the whole squadron, in all seventeen vessels, but during the night one escaped, and the next day arrived at New Orleans with my whole squadron.

At different times the English had sought to attack the pirates at Barrataria, in hopes of taking their prizes, and even their armed vessels. Of these attempts of the British, suffice it to instance that of June 23d, 1813, when two privateers being at anchor off Cat Island, a British sloop of war anchored at the entrance of the pass, and sent her boats to endeavor to take the privateers; but they were repulsed with considerable loss.

Such was the state of affairs, when on the 2d Sept., 1814, there appeared an armed brig on the coast opposite the pass. She fired a gun at a vessel about to enter, and forced her to run aground; she then tacked and shortly after came to an anchor at the entrance of the pass. It was not easy to understand the intentions of this vessel, who, having commenced with hostilities on her first appearance now seemed to announce an amicable disposition. Mr. Lafitte then went off in a boat to examine her, venturing so far that he could not escape from the pinnace sent from the brig, and making towards the shore, bearing British colors and a flag of truce. In this pinnace were two naval officers. One was Capt. Lockyer, commander of the brig. The first question they asked was, where was Mr. Lafitte? he not choosing to make himself known to them, replied that the person they inquired for was on shore. They then delivered to him a packet directed to Mr. Lafitte, Barrataria, requesting him to take particular care of it, and to deliver it into Mr. Lafitte's hands. He prevailed on them to make for the shore, and as soon as they got near enough to be in his power, he made himself known, recommending to them at the same time to conceal the business on which they had come. Upwards of two hundred persons lined the shore, and it was a general cry amongst the crews of the privateers at Grand Terre, that those British officers should be made prisoners and sent to New Orleans as spies. It was with much difficulty that Lafitte dissuaded the multitude from this intent, and led the officers in safety to his dwelling. He thought very prudently that the papers contained in the packet might be of importance towards the safety of the country and that the officers if well watched could obtain no intelligence that might turn to the detriment of Louisiana. He now examined the contents of the packet, in which he found a proclamation addressed by Col. Edward Nichalls, in the service of his Brittanic Majesty, and commander of the land forces on the coast of Florida, to the inhabitants of Louisiana. A letter from the same to Mr. Lafitte, the commander of Barrataria; an official letter from the honorable W.H. Percy, captain of the sloop of war Hermes, directed to Lafitte. When he had perused these letters, Capt. Lockyer enlarged on the subject of them and proposed to him to enter into the service of his Brittanic Majesty with the rank of post captain and to receive the command of a 44 gun frigate. Also all those under his command, or over whom he had sufficient influence. He was also offered thirty thousand dollars, payable at Pensacola, and urged him not to let slip this opportunity of acquiring fortune and consideration. On Lafitte's requiring a few days to reflect upon these proposals, Capt. Lockyer observed to him that no reflection could be necessary, respecting proposals that obviously precluded hesitation, as he was a Frenchman and proscribed by the American government. But to all his splendid promises and daring insinuations, Lafitte replied that in a few days he would give a final answer; his object in this procrastination being to gain time to inform the officers of the state government of this nefarious project. Having occasion to go to some distance for a short time, the persons who had proposed to send the British officers prisoners to New Orleans, went and seized them in his absence, and confined both them and the crew of the pinnace, in a secure place, leaving a guard at the door. The British officers sent for Lafitte; but he, fearing an insurrection of the crews of the privateers, thought it advisable not to see them until he had first persuaded their captains and officers to desist from the measures on which they seemed bent. With this view he represented to the latter that, besides the infamy that would attach to them if they treated as prisoners people who had come with a flag of truce, they would lose the opportunity of discovering the projects of the British against Louisiana.

Early the next morning Lafitte caused them to be released from their confinement and saw them safe on board their pinnace, apologizing the detention. He now wrote to Capt. Lockyer the following letter.

To CAPTAIN LOCKYER.
