A letter in the Daily Post of the 26th, dated from Charlestown, South Carolina, having laid the ill success at Fort St. Augustine on the ill conduct of ----, some particulars of which are: 1st, that the cattle taken at a cow-pen of one Diego, twenty-five miles from the town, May 12, were not distributed to the soldiery; 2d, that the people might have entered the town without opposition, but were not suffered; 3d, that the men were needlessly harassed; 4th, that Colonel Palmer, who was sent to Negro Fort, two miles from the town, with one hundred and thirty-three men to alarm the Spaniards was not supported by ----, who staid six or seven miles off; 5th, that Colonel Palmer being attacked by five hundred Spaniards, shot three of them after they had entered the fort; 6th, that Captain Warren was the life and spirit of the cause; 7th, that the Volunteers, seeing no prospect of succeeding under such mad conduct, as they called it, daily went off,--the following answer was published. "Upon seeing a letter misrepresenting, in the most false and malicious manner, the late expedition against St. Augustine; aiming thereby to defame the character of a gentleman, whose unwearied endeavors for the public service, have greatly impaired his health; and as I, who am a Captain in General Oglethorpe's regiment, was present, and acted upon that occasion as Brigadier Major, and must know the whole transactions, I think it my duty to take notice of it. "As to the cow-pen it speaks of, it is a square Fort, with four carriage guns and four swivel guns, and had a garrison in it of forty-seven soldiers of the regular troops, and seven negroes, who were all made prisoners of war. The cattle found there, and in parts adjacent, were distributed to the King's troops and the Carolina regiment. "In respect to the Carolina people being ready to enter the town of Augustine without opposition; it is entirely false, and without the least foundation. "In regard to Colonel Palmer's misfortune, who was killed in the first fire from the Spaniards; he brought it upon himself by disobeying the orders he received, which positively enjoined his keeping in the woods, and avoiding action, and by acting contrary to the advice of the officers under his command, some of whom were present when he received his orders, and lodging himself in the Negro Fort Moosa, where they were surrounded and defeated; the gates of which fort, and the house within it, the General had before burnt. "With respect to the Carolina Volunteers; that they did go away is certain, without leave given, or asked, and their Captain with them. A Captain of the Carolina regiment also left his command in the guard of the trenches, without being relieved, or asking any leave, and went with them. After such behavior, what credit can be given to such men, though termed persons of note?
