A Serjeant's party of Marines, in front of the whole, most promptly got into the embrasures, unperceived by the enemy, who, being seconded with much alacrity, the Dutch were finally driven from their works, the fort gained, and with it all the ships in the harbour. Much do I regret in not being able to give the name of this gallant Serjeant, who seemed to have combined talents with spirit. To commemorate the worthy deeds of the meanest Soldier, is a tribute justly due to him. The extensive observance of it would tend to rouse emulation, and the jealous pride of character. He who knows that he stands on the page of record, will be loth to forfeit so honorable a distinction. It is a conscious dignity which will accompany him into society, when his Country no longer wants his services; would diffuse its loyal influence amongst the private walks of life, and reanimate the possessor to become a ready Volunteer under every public emergency. If disabled by years, he may, perhaps, have an offspring, whom he cheerfully sends forth to battle, not the obdurate and callous victims to injured laws, not the mercenary and wretched auxiliaries of necessitous expedient, but the manly and independent assertors of Britain's rights and freedom. In resigned confidence, most willingly would he entrust their destinies to a corps, where courage and conduct never remain unnoticed, and are neither forgotten or pass away without recompence. Fort Ostenburgh was not gained, however, without a contest and loss; Lieutenant Long, who commanded a company of Seamen, was slain, besides 20 non-commissioned and private Sailors and Marines; Lieutenant Wolseley, of the Royal Navy, and Lieutenant Orr, of the Marine Grenadier Company, who officiated as Brigade Major with much credit to himself throughout this service, were wounded, as well as 40 of both descriptions.--Humanity, the brightest gem in the cap of a Soldier, became the property of each assaulter; who, when resistance ceased, spared, in every instance, his suppliant foe. Thus were our unnatural enemies expelled from the coast of Coromandel. Unanimity, the sure presage of success, was early apparent, and uniformly prevailed. I cannot yield a higher testimony, as to the merits of my Corps, than that which was bestowed by Sir Edward Hughes, in these words: "The whole of the Officers, who have been landed from the squadron for the attack of Negapatam, and this place, (Trincomale), have, on all occasions, manifested much honor, courage, and good conduct, and the private Seamen and Marines have acted with great steadiness and bravery." Major Geils, of the East India Company's Engineers, evinced great professional knowledge in his department.
