The sum of $2,026,139.68, which had been awarded to the claimants, was a liquidated and ascertained debt due by Mexico, about which there could be no dispute, and which she was bound to pay according to the terms of the convention. Soon after the final awards for this amount had been made the Mexican Government asked for a postponement of the time of making payment, alleging that it would be inconvenient to make the payment at the time stipulated. In the spirit of forbearing kindness toward a sister republic, which Mexico has so long abused, the United States promptly complied with her request. A second convention was accordingly concluded between the two Governments on the 30th of January, 1843, which upon its face declares that "this new arrangement is entered into for the accommodation of Mexico." By the terms of this convention all the interest due on the awards which had been made in favor of the claimants under the convention of the 11th of April, 1839, was to be paid to them on the 30th of April, 1843, and "the principal of the said awards and the interest accruing thereon" was stipulated to "be paid in five years, in equal installments every three months." Notwithstanding this new convention was entered into at the request of Mexico and for the purpose of relieving her from embarrassment, the claimants have only received the interest due on the 30th of April, 1843, and three of the twenty installments. Although the payment of the sum thus liquidated and confessedly due by Mexico to our citizens as indemnity for acknowledged acts of outrage and wrong was secured by treaty, the obligations of which are ever held sacred by all just nations, yet Mexico has violated this solemn engagement by failing and refusing to make the payment. The two installments due in April and July, 1844, under the peculiar circumstances connected with them, have been assumed by the United States and discharged to the claimants, but they are still due by Mexico. But this is not all of which we have just cause of complaint. To provide a remedy for the claimants whose cases were not decided by the joint commission under the convention of April 11, 1839, it was expressly stipulated by the sixth article of the convention of the 30th of January, 1843, that-- A new convention shall be entered into for the settlement of all claims of the Government and citizens of the United States against the Republic of Mexico which were not finally decided by the late commission which met in the city of Washington, and of all claims of the Government and citizens of Mexico against the United States.
