Having received several memorials from the British Minister on subjects arising out of the present war, I take the liberty of enclosing them to you, and shall add an explanation of the determinations of the government thereon. These will serve to indicate the principles on which it is meant to proceed; and which are to be applied, with impartiality, to the proceedings of both parties. They will form, therefore, as far as they go, a rule of action for them and for us. In one of these memorials, it is stated, that arms and military accoutrements are now buying up by a French agent in this country, with an intent to export them to France. We have answered, &c. ***** Another of these memorials complains that the Consul of France at Charleston, has condemned, as legal prize, a British vessel captured by a French frigate, observing that this judicial act is not warranted by the usage of nations nor by the stipulations existing between the United States and France. It is true, &c. ***** Our information is not perfect on the subject matter of another of these memorials, which states that a vessel has been fitted out at Charleston, manned there, and partly too with citizens of the United States, received a commission there to cruise against nations at peace with us, and has taken and sent a British vessel into this port. Without taking all these facts for granted, we have not hesitated to express our highest disapprobation of the conduct of any of our citizens who may personally engage in committing hostilities at sea against any of the nations, parties to the present war, and to declare, that if the case has happened, or that should it happen, we will exert all the measures with which the laws and constitution have armed us, to discover such offenders and bring them to condign punishment. And that the like conduct shall be observed, should the like enterprises be attempted against your nation, I am authorized to give you the most unreserved assurances. The capture of the British ship Grange, by the French frigate L’Embuscade, within the Delaware, has been the subject of a former letter to you. On full and mature consideration, the government deems the capture to have been unquestionably within its jurisdiction, and that according to the rules of neutrality and the protection it owes to all persons while within its limits, it is bound to see that the crew be liberated, and the vessel and cargo restored to their former owners. The Attorney General of the United States has made a statement of the grounds of this determination, a copy of which I have the honor to enclose you. I am, in consequence, charged by the President of the United States to express to you his expectation, and at the same time his confidence that you will be pleased to take immediate and effectual measures for having the ship Grange and her cargo restored to the British owners, and the persons taken on board her set at liberty.
