DEAR SIR,--I congratulate you on your safe arrival with Miss Clinton at New York, and especially on your escape from British violence. This aggression is of a character so distinct from that on the Chesapeake, and of so aggravated a nature, that I consider it as a very material one to be presented with that to the British Government. I pray you, therefore, to write me a letter, stating the transaction, and in such a form as that it may go to that Government. At the same time, I must request you to instruct Mr. Gelston, from me, to take the affidavits of the Captain of the revenue cutter, and of such other persons as you shall direct, stating the same affair, and to be forwarded, in like manner, to our Minister in London. You will have seen by the proclamation, the measures adopted. We act on these principles, 1. That the usage of nations requires that we shall give the offender an opportunity of making reparation and avoiding war. 2. That we should give time to our merchants to get in their property and vessels and our seamen now afloat. And 3. That the power of declaring war being with the Legislature, the executive should do nothing, necessarily committing them to decide for war in preference of non-intercourse, which will be preferred by a great many. They will be called in time to receive the answer from Great Britain, unless new occurrences should render it necessary to call them sooner. I salute you with friendship and respect. TO COLONEL TATHAM. WASHINGTON, July 6, 1807. SIR,--Your favor of the 1st instant has been received, and I thank you for the communication. Considering the mass of false reports in circulation, and the importance of being truly informed of the proceedings of the British armed vessels in the Chesapeake and its vicinities, I should be very glad, as you are on the spot, provided with a proper vessel and men, if you could continue watching their motions constantly, and giving me information of them. In that case it would be necessary you should journalize everything respecting them which should fall within your observation, and enclose daily to me a copy of the observations of the day, forwarding them to the post-office of Norfolk, by every opportunity occurring. Your allowance should be exactly on the same footing as when you were surveying the coast, and for current expenses you may draw on Mr. Bedinger, Navy Agent, at Norfolk, only accompanying each draught with a letter explaining generally the purpose of it, which is a constant and indispensable rule in all our departments. It will be necessary for me to ask the continuance of this service from you only until I can ascertain the course these officers mean to pursue. I salute you with esteem and respect. TO THE SECRETARY AT WAR. WASHINGTON, July 7, 1807.
