In the year 1821, the Neapolitan general, Carascosa, announced his determination of calling out Lieutenant-General Pepe, late commander of the Neapolitan forces. Very shortly after General Pepe’s arrival in London, which was on the 1st of February, 1823, he received a letter from General Carascosa, in which that officer, after charging General Pepe with conduct injurious to his reputation, avowed his opinion that military revolutions were, in all cases, contrary to the principles of honour; and that any change in the government of Naples was unnecessary, still less in that of Spain. The letter concluded with a challenge in the usual terms. To this letter General Pepe replied, by declaring his opinion, that every free state was indebted for its liberty to military revolution, not excepting even England; that the Spaniards were now a prey to civil anarchy, only because certain individuals calling themselves Liberals were, in fact, hostile to the constitution of the Cortes; and that he had employed the authority which his rank and his command had given him at Naples, to resist the despotism of a government which, while it rendered the people miserable, was of no actual advantage to the reigning dynasty. He concluded by accepting the challenge. On the 20th of February, the generals met. Count Santa Rosa, ex-minister of war of Piedmont, attended General Pepe, and M. Brunet, a French gentleman, General Carascosa. The weapons were swords, and the combatants engaged; but at the second pass, General Pepe’s sword snapped short near the guard; upon which the seconds interfered, and the combat, as is usual in such cases, was deferred. A second meeting took place on the 28th of February, not far from Kew Bridge. On engaging, General Carascosa attacked with great impetuosity; but after several passes on both sides, General Pepe, seizing his adversary’s sword with his left hand, disarmed him, and placing the point of his sword at his breast, had his life in his power. Here the affair would have terminated, but General Carascosa, on recovering his sword, renewed the combat; which was warmly maintained, until he was finally disabled by a thrust from General Pepe in the right shoulder. General Pepe, seeing his adversary incapable of further defence, declined availing himself of his advantage; and thus the duel terminated. BETWEEN COLONEL GRAVES AND CAPTAIN LACY. May, 1823.
