Sir John Borlase Warren to Mr. Monroe.

Halifax, September 30, 1812.

Sir: Having received information that a most unauthorized act has been committed by Commodore Rodgers, in forcibly seizing twelve British seamen, prisoners of war, late belonging to the Guerriere, and taking them out of the English cartel brig Endeavor on her passage down the harbor of Boston, after they had been regularly embarked on board of her for an exchange, agreeable to the arrangements settled between the two countries, and that the said British seamen so seized, are now detained on board the United States frigate President as hostages; I feel myself called upon to request, sir, your most serious attention to a measure so fraught with mischief and inconvenience, destructive of the good faith of a flag of truce and the sacred protection of a cartel. I should be extremely sorry that the imprudent act of any officer should involve consequences so particularly severe as the present instance must naturally produce, if repeated; and although it is very much my wish, during the continuance of the differences existing between the two countries, to adopt every measure that might render the effect of war less rigorous, yet, in another point of view, the conviction of the duty I owe my country would, in the event of such grievances as I have already stated being continued, not admit of any hesitation in retaliatory decisions; but as I am strongly persuaded of the high liberality of your sentiments, and that the act complained of has originated entirely with the officer who committed it, and that it will be as censurable in your consideration as it deserves, I rely upon your taking such steps as will prevent a recurrence of conduct so extremely reprehensible in every shape.

I have the honor to be, with the highest consideration, sir, your most obedient and most faithful humble servant,

JOHN BORLASE WARREN,
Admiral of the Blue, Commander-in-Chief, &c.

James Monroe, Esq., Secretary of State.

Mr. Monroe to Sir John Borlase Warren.

Department of State, Oct. 28, 1812.

Sir: I have had the honor to receive your letter of the 30th September, complaining that Commodore Rodgers, commanding a squadron of the United States Navy at the port of Boston, had taken twelve British seamen, lately belonging to His Britannic Majesty's ship the Guerriere, from a cartel in the harbor of Boston, and that he had detained them on board the President, a frigate of the United States, as hostages.

I am instructed to inform you, that inquiry shall be made into the circumstances attending, and the causes which produced the act, of which you complain; and that such measures will be taken, on a knowledge of them, as may comport with the rights of both nations, and may be proper in the case to which they relate.
