Other reports state him to have said that there had been three obstinate engagements between the French and the Swedes, in which gi eat numbers had been killed and wounded on both sides, and at the close of which the Swedes bad rema:ned maters of the field of battle. The only fact Litlit•rto fully ascertained, however, is, that Mr. COCKBURN actually left Ilamburgh or the 18th instant, but it was to vi , it the head-quarters of the Swedish army,. and to urge its ad vance for the relief of flamburgh. FALL OF CASTRO. Last niiiht's Gazette contains dispatches from Captain ROBERT BLOYE, of the Lyra, dated off Bermeo, May 13, avid giving an account of the capture of Castro, by the enemy on the 1 lth, after a most gallant resistance on the part of the garrison asiisted by some of our men. The whole garrison, except the wounded, with many of the inhabitants, were brought off by our ships with a trifling loss. .Lord CATHCART'S dispatches respecting the battle of Lutzen will be found in another part of our paper. They are neither clear nor satisfactory. flis Lordship only claims a success on the part of the Allies: he mentions that the French having fought on the defensive all day, became the assailants in the evening, and as the right wing of the Allies changed its.front, and the whole of their cavalry was brought from the left to fall on the advancing enemy, he hoped to innie witnessed the. destruction of BUONAPARTE and his whole army, instead of which he only saw the flashes of the guns tluough the darkness, which overtook the combatants before. the cavalry could arrive, Tie does not explain the reasons which induced the Allies to fall back across the Elbe, and thus allowed the whole Saxon army to join the French. We had prepared some observations on the defeat of the Catholics, by a majority of four, %%hid) the unexpected in flux of foreign matter of primary importance compels us to postpone. It is reported, that the SPEAKER is now em plo)ed in prepatin; a Bill, throwing open the Law, the Army, and the Navy, to the Catholics ; hut excluding them from sitting in Pailiament. We fear the Catholics have been too near the attainment of their object to be contented midi smaller concessions. Friday a Mail arrived from Lisbon with letters and papers to the 12th instant.

The Spanish forces are also mustering strong, and al e in excellent condition. The division under PoßttEa has moved tow.:rds Leon.

MAY SO. American Papers have brought us an Act of Congress cal culated to excite the highest indignation. The first section authorises" full and ample retaliation to be made according to the laws and usages of war" should any of those laws and usages be violated by any act of violence on the part of the British. • With this we have no fault to find. The second section is to inflict retaliation when, and where" the established laws and usages of war" do not allow it. To quote it will be sufficient to show both its injustice and atrocity. Only the dread of still severer retaliation, and the most signal offensive hostilities on our part can bring Mr. MADISON and the American Congress to their senses. In all cases where any outrage or act of cruelty or barbarity shall be or have been practised by any Indian or Indians in alliance with the British Government, or in connection those actiog under the autho rity of the said Governnient, against Citizens of the 'Jolted States, or those under its protection, the President of the United States is hereby authorised to cause full and ample retaliation to be done and executed on dll such British subjects, soldiers, seamen. or marines, ur Indians, n alliance or connection with Great Britain, being, prisoners of war, as the gime mtrar, or act of cruelty. or barb arity, had been dune under file authority of the British Gi,vernment." A vessel has arrived at Plymouth, belonging to London, which was taken by an American privateer, and was recar tured by the Hydra. The ship alluded to had 17 passengers on board, and on her capture an indiscriminate and most shameful pillage ensued. The Captain of the privateer himself took from the English Captain his spying-glass, quadrant, and other. instruments -useful in navigatiop, while his Officers and crew plundered the passengers of every thing but that which they wore. From one lady they took 13 pair of silk hose; and, to complete the scene, the English crew entered into the American service. The Hydra fri gate, however, fortunately fell in with, and captured, the privateer and prize, and the Officers of the Hydra, on being informed of what had occurred, directed the passengers to take by force from the Americans their ill-gotten plunder; a permission•which was immediately acted on, and the whole of the stolen notes, cash, watches, cloathes, &c. were reco vered. The next act of justice was to send the English crew, who had deserted the coloers of their country, on board the Salvador del Mundo, in Hainoaze, where they now are. The Captain of the privateer boastingly informed the English Captain, that the American frigates were deter. mined to engage, and he had no doubt would carry our se• venty-fours The Arethusa frigate is arrived at Portsmouth from Vera Cruz. She has on boar d 472,000 dollars for Government, and 300,000 for merchants. The Arethusa brings accounts. that the insurgents in Mexico are greatly reduced, and incapable of much resistance. On the .sth of March, three millions and a half of dollars arrived at Vera Cruz from Mexico, under the protection of a small escort. The Arethusa arrived at Bermuda, on her way to England, on the 2d of Mai', having touched both at Jamaica and Havannah.
