US Presidency
1846

The Government of the United States made repeated reclamations on behalf of its citizens, but these were answered by the perpetration of new outrages. Promises of redress made by Mexico in the most solemn forms were postponed or evaded. The files and records of the Department of State contain conclusive proofs of numerous lawless acts perpetrated upon the property and persons of our citizens by Mexico, and of wanton insults to our national flag. The interposition of our Government to obtain redress was again and again invoked under circumstances which no nation ought to disregard. It was hoped that these outrages would cease and that Mexico would be restrained by the laws which regulate the conduct of civilized nations in their intercourse with each other after the treaty of amity, commerce, and navigation of the 5th of April, 1831, was concluded between the two Republics; but this hope soon proved to be vain.
