H.R. 145, A bill providing for the prosecution of the war between the United States and Mexico, May 1846

Congress declared war against Mexico in 1846, claiming that a state of war existed “by the act of the Republic of Mexico.”  That “act”—Mexican forces wounding U.S. soldiers in a skirmish—occurred after President James K. Polk sent troops into a disputed border area. This printed House bill shows revisions by the Senate before passage.
