That of 8 July (1 p.) enclosed copies of documents related to the 6 Apr. 1815 massacre of American prisoners at Dartmoor, including a 7 Apr. 1815 report by a committee of the survivors to U.S. agent for prisoners Reuben G.

For summaries of these documents, see JM to Monroe, 12 June 1815, n. 3. Adams also enclosed copies of a 26 Apr. 1815 report on the affair by commissioners Charles King and Francis Seymour Larpent (9 pp.; printed ibid., 21–23), concluding that much of the force used against the prisoners had been unjustified but that it was impossible to identify individual perpetrators; and King to Adams, 26 Apr. 1815 (3 pp.; printed ibid., 4:20), forwarding his and Larpent’s report and stating that the prisoners had told him they blamed Beasley rather than the U.S. government for their lengthy detention.

Adams’s letter to Monroe of 14 July 1815 (2 pp.) described the U.S. negotiators’ successful efforts to establish an equitable order for naming the parties to, and signing, the commercial treaty with Great Britain. He enclosed a printed copy of the Prince Regent’s 12 July 1815 speech to Parliament (2 pp.), which mentioned the treaty favorably. In his 15 July dispatch (1 p.), Adams acknowledged receipt of Monroe’s instructions of 11 May 1815, together with copies of the secretary of state’s correspondence with Anthony St. John Baker on the British failure to return U.S. slaves, the alleged sale of some of those slaves in the West Indies, and the delayed evacuation of British military posts in U.S. territory (for the correspondence, see Monroe’s letters to JM of 3 Apr. 1815, and n. 2; 8 Apr. 1815, and n. 2; 11 Apr. 1815, and n. 4; and 9 May 1815, and n. 1). Adams stated that he had broached the topic of the slaves with Lord Castlereagh and would pursue it, with the hope that Monroe could provide solid evidence to support U.S. claims. On 19 July 1815 (3 pp.), Adams reported on U.S. consular affairs in Great Britain, enclosing copies of his correspondence with the Foreign Office regarding Beasley’s authority to act as U.S. consul in London, and with the Prussian chargé d’affaires Friedrich von Greuhm regarding the appointment of Prussian consuls in U.S. ports (1 p.).

3. The 3 July 1815 letter to Monroe from Adams, Clay, and Gallatin (6 pp.; DNA: RG 59, Despatches of the U.S. Commissioners at Ghent; printed in ASP description begins American State Papers: Documents, Legislative and Executive, of the Congress of the United States … (38 vols.; Washington, D.C., 1832–61). description ends , Foreign Relations, 4:11–12) summarized their treaty negotiations and stated that they had deliberately excluded any provisions relating to seamen because they were convinced the British would not negotiate on that issue. In addition to a copy of the 3 July 1815 treaty, the enclosures (29 pp.; printed ibid., 7–8, 12–18) included copies of the undated proposed treaty submitted by the American to the British commissioners; the 16 June 1815 British counterproposal with two separate articles restricting U.S. trade with British colonies in Africa and the East Indies; and the notes exchanged during the negotiation from 17 to 30 June 1815.
