I dare say that Purcell's map must be of value, and it would be well if his representatives would publish it, but whether worth your purchase, and at what price, General Wilkinson might perhaps satisfy you. I shall write to Marentille that if you think it worth while to give him fifty thousand dollars for his project, you will inform him. In the contrary case, it may be put away in your pigeon hole of projects. Governor Cabell, after informing me of the orders for the discharge of the militia, except a company of artillery, and one of cavalry, as we directed, adds: "I have, however, in pursuance of the advice of council, done what your letter did not expressly authorize. But when I state to you the reasons which influenced the measure, I hope you will approve it. You relied entirely on the troop of horse for cutting off the supplies. But we have received the most satisfactory information of the insufficiency of cavalry to perform that service, in consequence of the particular nature of the country in which they have to act. It is covered with sandbanks and hills, which, in many places (where supplies are most easily procured), render cavalry incapable of action. So severe has this service been, that it has already almost knocked up as fine a battalion of cavalry as any in the United States, perhaps as any in the world. Influenced by these considerations, which we believe had not presented themselves to your mind, because you had not received the necessary information as to facts, the executive have called into service a company of infantry from the county of Princess Anne, to co-operate with the cavalry in cutting off the supplies. Since giving these orders, I understand that General Mathews has anticipated us by calling into actual service the very force we contemplated." Our object was certainly to prevent supplies, and if the means we thought of are not adequate, we should, had we known all circumstances, have provided what would have been effectual; for I think the point of honor requires we should enforce the proclamation in those points in which we have force sufficient. I shall await your opinion, however, before I answer the Governor's letter. Information as late as August 3d, shows that the squadron was quiet in and near the Bay, and General Thomas Hardy, to whom Tazewell delivered the five men, declared to him that his objection to intercourse by flag, was that the two nations were not in a state of war, which alone required it. He said he expected Barclay, or General Robert Lowrie, in a week to take the command. I salute you with sincere affection and respect. TO HIS EXCELLENCY GOVERNOR CABELL. MONTICELLO, August 7, 1807.
