1. Monroe’s letter to Daniel Brent has not been found, but it probably enclosed Monroe to Maj. Gen. James Wilkinson, 14 Sept. 1813, informing Wilkinson that Sir George Prevost had threatened retaliation against the United States for what he considered to be the irregular exchange of Brig. Gen. William Hull and other American officers for British troops captured from the transport Samuel and Sarah. Monroe argued at length that the exchange was valid, stated that the subject would be amicably dealt with by the two countries’ commissaries for prisoners, and observed that Prevost would do well to avoid “any act of injustice or violence” that might “produce a different result” (DNA: RG 59, War of 1812 Papers, U.S. Marshals’ Returns of Enemy Aliens and Prisoners of War, Part II; printed in Michigan Pioneer and Historical Collections 15 [1890; reprint, Lansing, Mich., 1909]: 385–88).
