S Patterson, of the Fritted State* Frigate Congress, whose melancholy lute, lias casi a deep gloom over us all. Never has the annals ol crime recorded a more daring or cold-blooded mur der. From the information I can gam upon the subject, it man follow*:—About 11 o'clock on the evening of the 28th ult., Lieut* Hunter and Dod (of this ship) in descending the hill leading to the wharl, were suddenly startled by the exclamation oflet me go, mingled with the noise ol a scuffle, and tlie jingling sound of a weapou falling over the precipice. Upon hearing this, the lor-mer handed one of hispiatola to the latter, aodrushed toward the *|Kt Irom whence the sound proceeded. In ascending the hill, Mr Patterson, ('hedeceased) passed them, and exclaimed, oh, my Hod, i am stabbed. After an elapse of a few moments, both Messrs. Hunter and Dod returned, (not linding any trace of the perpetrator, or perpetrators,) owing 10 the utter darkness of the night, and discovered Mr. P. upon the ground, a lifeless corpse!Mr. H. remained by the body, whilst Mr. I), proceeded to the foot of the hill fora hghtlduring which die former hailed the Congress for assistance. Mr. P. shortly .afterward returned, and with the Hfiwis-lance of Dr. llaxtvr, of the C»ngreb£, who. coining up behind, succeeded in bringing the body to the finding place. Meanwhile, Mr. Hunter's calls for help were answered by the immediate lowering of a boat, and, in the twinkling of an eye, the second cutler ol the CongreiA, together with two boats from the Fairfield, were at the wharf, loaded to their gunwales with the officers and crews of both ships, armed with hoarding pikes, cutlasses, and pistols, determined, upon learning of Mr. Patterson’s death, to exterminate the first Spaniard who dared to near the Spot, and in spite o| the orders and commands ol Lieutenant Hunter, (who hod, during this important crisis, exhibited that degree of coolness and deliberation, which constitutes one of the moat important traits of his amiable character,) they persisted in leaving their baats, and not until the arrival of a number of officers, were they ordered back.Upon examination of the body, three woundswere discovered, one on the left breast, penetrating ihe heart—the others were received in the right trm, evidently defending his body from the deadly weapon of the villain who merely for sordid gain, .“truck the latal blow, and terminated the existence of one “whose memory will long be cherished in the hearts of his countrymen.Yesterday (Sunday) the remains ol the laineuted Mr. Patterson were committed to the “silent tomb. The funeral procession was Urge, composed of theofficers of a Swedish and French vessel of war, lyingof Iin ihe harbor, as also the officers and crews of the different ships coni|Kaing the squadron.The greatest excitement prevails throughout our squadron, and prompt measures have been taken toapprehend the fugitive. A reward of $500 has been iDi6*b scribed and offered for the arrest of tue assassin. In haste, yours, respectfully, c., Y.©
