SIR: I have had the honor to receive your letter of the 2d instant from St. Marys, where you had arrived in discharge of the trust reposed in you by the President, in relation to East Florida.

My letter by Mr. Isaacs has, I presume, substantially answered the most important of the queries submitted in your letter, but I will give to each a more distinct answer.

By the law of which a copy was forwarded to you it is made the duty of the President to prevent the occupation of East Florida by any foreign power. It follows that you are authorized to consider the entrance, or attempt to enter, especially under existing circumstances, of British troops of any description as the case contemplated by the law, and to use the proper means to defeat it.

An instruction will be immediately forwarded to the commander of the naval force of the United States in the neighborhood of East Florida to give you any assistance, in case of emergency, which you may think necessary and require.

It is not expected, if you find it proper to withdraw the troops, that you should interfere to compel the patriots to surrender the country or any part of it to the Spanish authorities. The United States are responsible for their own conduct only; not for that of the inhabitants of East Florida. Indeed, in consequence of the compromitment of the United States to the inhabitants, you have been already instructed not to withdraw the troops, unless you find that it may be done consistently with their safety, and to report to the Government the result of your conferences with the Spanish authorities, with your opinion of their views, holding in the meantime the ground occupied.

In the present state of our affairs with Great Britain the course above pointed out is the more justifiable and proper.

I have the honor, etc.,

JAMES MADISON.

JULY 6, 1812.
