The Notes to Foreign Legations in the United States From the Department of State, 1834-1906, M99 (roll 85) includes the following communications addressed to the Spanish Legation:

Dec. 12, 1839: Secretary of State John Forsyth acknowledges receipt of recent notes from the Spanish Legation concerning the Amistad and its occupants, and states that the imputed delay in the case is consonant with the importance of it, that the Spanish minister does not accurately interpret the nature and workings of the American judicial process, and that the Federal Government has not absolved itself of any responsibility for the case.
Jan. 6, 1840: Secretary of State John Forsyth indicates that the U.S. will accede to the request of the Spanish minister and provide naval escort in conveying the Amistad and its occupants to Cuba, together with any and all pertinent documents, if the necessity arises.
May 9, 1840: State Department acknowledges note from the Spanish minister intimating his approval of the resolutions of the Senate Foreign Relations Committee on the Amistad case, and says that the President, who is in sympathy with these resolutions, is nevertheless obliged to adhere to certain established rules of conduct in these matters.
Apr. 3, 1841: State Department forwards two letters to the Spanish minister, one of them from a US Judge of the Circuit Court, relative to Antonio, the African aboard the Amistad who was declared to be a slave.
Sept. 1, 1841: Secretary of State Daniel Webster acknowledges the Spanish minister's note of May 29 that suggests that the provisions of the treaty of 1795 were not precisely respected in the Amistad case. Webster's response, totaling seven pages, is a statement of policy to the effect that the Spanish minister has no grounds for charging illegal or criminal conduct on the part of the United States in the matter, that the treaty provisions of 1795 are adjudicable in a domestic court, and that the minister does not properly appreciate the American judicial system.
June 21, 1842: Secretary of State Daniel Webster's second major statement on the question, totaling 12 pages, in which he states that a factual synopsis of the case is the best evidence for concluding that, unless the Spanish Government can show and prove that the Amistad decision was corruptly decided or failed to conform to established principles of equity, justice, and impartiality, it has no grounds for remonstrance. Extradition, according to Webster, lies within the discretion of the government directly concerned; such a decision is primarily unilateral.
Secretary of State John Forsyth to W.S. Holabird, Sept. 11, 1839, stating that the department has received a communication from the Spanish minister invoking the treaty of 1795 and demanding release of the Amistad and its occupants. Papers are to be laid before the President, and Holabird should do nothing to place the matter beyond Federal control in the meantime.
Forsyth to W.S. Holabird, Sept. 23, 1839, requesting copies of the ship's papers and a transcript of the inquiry just held.
Forsyth to Attorney General Felix Grundy, Sept. 24, 1839, forwarding pertinent documents in the Amistad case and requesting that an opinion be rendered on the merits of the Spanish minister's appeal to the treaty of 1795.
Forsyth to Secretary of the Navy James K. Paulding, Jan. 7, 1840, acknowledging receipt of recent letter stating that the US schooner Grampus is to be ordered to New Haven to stand by pending a decision in the Amistad case and the possible return of the Africans to Havana.
Forsyth to W.S. Holabird, Jan. 6, 1840, stating in response to appeal of the Spanish minister, that the US will provide a naval escort for the Amistad once the decision is rendered, that Lieutenants Gedney and Mead will be ordered to Cuba to provide testimony in any proceedings held there, that Holabird is to insure that these officers are in possession of all pertinent documents, and that the Amistad is to be safeguarded until released to the representative of the Spanish Government.
Forsyth to W.S. Holabird, Jan. 12, 1840, instructing him to execute the President's wishes unless an appeal is filed in the case, that he is not to take such an appeal for granted, and that should the decision not be as anticipated, Holabird himself is to file an appeal.
Forsyth to W.S. Holabird, Jan. 17, 1840, forwarding instructions that the President desires the late Amistad decision to be appealed, and that he in the meantime is to work with any movement interested in preventing the diminution in value of the ship, consonant with the rights of all concerned.
Forsyth to W.S. Holabird, Feb. 8, 1840, stating that in accordance with the wishes of the Spanish minister, the Negro Antonio of the Amistad is to remain in the US.
W.S. Holabird, US District Attorney, Winchester, CT, to Secretary of State, Sept. 5, 1839, apprising him of the detention of 41 Africans from the ship Amistad, explaining that the court is to sit Sept. 17, and asking that he be assigned an assistant.
Holabird to Secretary of State, Sept. 9, 1839, inquiring after treaty provisions which exist and which may authorize release of the Africans to the Spanish Government, and whether this can be done before court convenes.
Robert Routoul, Jr., Boston, to President, Sept. 12, 1839, interpreting stir of public interest in the Amistad case.
Seth Staples and Theodore Sedgwick, New York, counsel for defense of the Africans, to Secretary of State, Sept. 13, 1839, presenting their views on the case, and requesting that they be notified in advance if the Africans are to be released to the Spanish Government since they intend to contest the surrender.
Holabird to Secretary of State, Sept. 21, 1839, acknowledging receipt of department's instructions.
Holabird to Secretary of State, Oct. 13, 1839, indicating the Amistad ship papers are not yet available for transmission as requested but will be forwarded at the earliest opportunity.
Holabird to Secretary of State, Nov. 5, 1839, forwarding copies of Amistad papers and of first warrant issued upon incarceration of the Africans. The enclosures include a manifest of Amistad's cargo, and identification of 41 occupants, including names (in Spanish with translation).
