The President again brought this subject before Congress by his annual message of December, 1860. Mr. Lincoln had now been elected President and the foreign relations of the country would in three months be in his hands. At this time, however, it had become still more necessary for the United States Government to determine, and to determine promptly, whether it would leave American citizens to the mercy of Miramon’s government, or whether it would do something to establish the constitutional government of Juarez. Again the President repeated the warning that foreign powers would interfere if this matter were to be much longer neglected, although at that moment informal and verbal assurances had been given by some of the European diplomatists in Mexico that such interference was not intended. Congress, however, spent the whole winter of 1860-61 in a dreary discussion of our internal affairs, without either making any effort to arrest the spread of secession by conciliatory measures, or doing anything to strengthen the hands of the President or his successor.

But it had been for some time apparent to Mr. Buchanan that our relations with Mexico could not be left in the condition in which they stood. Both to satisfy the long deferred claims of our citizens, and to prevent foreign interference with the internal affairs of Mexico, he had instructed Mr. McLane to make a treaty with the Constitutional government. On the 14th of December, 1859, a “Treaty of Transit and Commerce” was signed between the Mexican Republic and the United States, and also a “Convention to enforce treaty stipulations, and to maintain order and security in the territory of the Republics of Mexico and the United States.” Great advantages of trade, transit and commerce were secured by these arrangements. The United States was to pay $4,000,000 for the surrender of certain Mexican duties, two millions to be paid down, and two millions to be reserved and distributed to the American claimants who could prove their injuries. With the two millions to be placed in the hands of the constitutional government, it was expected that it would be able to expel the usurping government from the capital and establish itself over the whole territory of the republic. All acquisition of further Mexican territory was thus avoided. If this treaty had been approved by the Senate of the United States, the empire of Maximilian would never have been heard of. The American negotiator, Mr. McLane, in his despatch to the Secretary of State, dated on the day this treaty and convention were signed at Vera Cruz, expressed his apprehension that if they were not ratified, further anarchy would prevail in Mexico, until it should be ended by interference from some other quarter. The President submitted the treaty and the convention to the Senate on the 24th of January, 1860. They were neither of them approved. Mexico was left to the interference of Louis Napoleon; the establishment of an empire, under Maximilian, a prince of the House of Hapsburg, followed, for the embarrassment of President Lincoln’s administration while we were in the throes of our civil war, and the claims of American citizens were to all appearance indefinitely postponed.

The relations of the United States with Spain at the commencement of Mr. Buchanan’s administration, and the manner in which he dealt with them, have been described by him as follows:

Our relations with Spain were in a very unsatisfactory condition on his accession to power. Our flag had been insulted, and numerous injuries had been inflicted on the persons and property of American citizens by Spanish officials acting under the direct control of the Captain General of Cuba. These gave rise to many but unavailing reclamations for redress and indemnity against the Spanish government. Our successive ministers at Madrid had for years ably presented and enforced these claims, but all without effect. Their efforts were continually baffled on different pretexts. There was a class of these claims called the “Cuban claims,” of a nature so plainly just that they could not be gainsayed. In these more than one hundred of our citizens were directly interested. In 1844 duties were illegally exacted from their vessels at different custom houses in Cuba, and they appealed to the Government to have these duties refunded. Their amount could be easily ascertained by the Cuban officials themselves, who were in possession of all the necessary documents. The validity of these claims was eventually recognized by Spain, but not until after a delay of ten years. The amount due was fixed, according to her own statement, with which the claimants were satisfied, at the sum of $128,635.54. Just at the moment when the claimants were expecting to receive this amount without further delay, the Spanish government proposed to pay, not the whole, but only one-third of it, and this provided we should accept it in full satisfaction of the entire claim. They added that this offer was made, not in strict justice, but as a special favor.

Under these circumstances, the time had arrived when the President deemed it his duty to employ strong and vigorous remonstrances to bring all our claims against Spain to a satisfactory conclusion. In this he succeeded in a manner gratifying to himself, and it is believed to all the claimants, but unfortunately not to the Senate of the United States. A convention was concluded at Madrid on the 5th March, 1860, establishing a joint commission for the final adjudication and payment of all the claims of the respective parties. By this the validity and amount of the Cuban claims were expressly admitted, and their speedy payment was placed beyond question. The convention was transmitted to the Senate for their constitutional action on the 3d May, 1860, but on the 27th June they determined, greatly to the surprise of the President, and the disappointment of the claimants, that they would “not advise and consent” to its ratification.

The reason for this decision, because made in executive session, cannot be positively known. This, as stated and believed at the time, was because the convention had authorized the Spanish government to present its Amistad claim, like any other claim, before the Board of Commissioners for decision. This claim, it will be recollected, was for the payment to the Spanish owners of the value of certain slaves, for which the Spanish government held the United States to be responsible under the treaty with Spain of the 27th October, 1795. Such was the evidence in its favor, that three Presidents of the United States had recommended to Congress to make an appropriation for its payment, and a bill for this purpose had passed the Senate. The validity of the claim, it is proper to observe, was not recognized by the convention. In this respect it was placed on the same footing with all the other claims of the parties, with the exception of the Cuban claims. All the Spanish government obtained for it was simply a hearing before the Board, and this could not be denied with any show of impartiality. Besides, it is quite certain that no convention could have been concluded without such a provision.

It was most probably the extreme views of the Senate at the time against slavery, and their reluctance to recognize it even so far as to permit a foreign claimant, although under the sanction of a treaty, to raise a question before the Board which might involve its existence, that caused the rejection of the convention. Under the impulse of such sentiments, the claims of our fellow-citizens have been postponed if not finally defeated. Indeed, the Cuban claimants, learning that the objections in the Senate arose from the Amistad claim, made a formal offer to remove the difficulty by deducting its amount from the sum due to them, but this of course could not be accepted.[[44]]

The following account of an expedition which President Buchanan found it necessary to send to Paraguay, is also taken from his Defence of his Administration:

The hostile attitude of the government of Paraguay toward the United States early commanded the attention of the President. That government had, upon frivolous and even insulting pretexts, refused to ratify the treaty of friendship, commerce and navigation, concluded with it on the 4th March, 1853, as amended by the Senate, though this only in mere matters of form. It had seized and appropriated the property of American citizens residing in Paraguay, in a violent and arbitrary manner; and finally, by order of President Lopez, it had fired upon the United States steamer Water Witch (1st February, 1855), under Commander Thomas J. Page of the navy, and killed the sailor at the helm, whilst she was peacefully employed in surveying the Parana river, to ascertain its fitness for steam navigation. The honor, as well as the interests of the country, demanded satisfaction.

The President brought the subject to the notice of Congress in his first annual message (8th December, 1857). In this he informed them that he would make a demand for redress on the government of Paraguay, in a firm but conciliatory manner, but at the same time observed, that “this will the more probably be granted, if the Executive shall have authority to use other means in the event of a refusal. This is accordingly recommended.” Congress responded favorably to this recommendation. On the 2d June, 1858,[[45]] they passed a joint resolution authorizing the President “to adopt such measures, and use such force as, in his judgment, may be necessary and advisable, in the event of a refusal of just satisfaction by the government of Paraguay, in connection with the attack on the United States steamer Water Witch, and with other matters referred to in the annual message.”[[46]] They also made an appropriation to defray the expenses of a commissioner to Paraguay, should he deem it proper to appoint one, “for the adjustment of difficulties” with that republic.
