…this House desires to obtain a full knowledge of all the facts which go to establish whether the particular spot of soil on which the blood of our citizens was so shed, was, or was not, our own soil, at that time…
In 1846, President James K. Polk had asked Congress to declare war with Mexico, he claimed that Mexico had “passed the boundary of the United States … invaded our territory and shed American blood upon America’s soil.” As a result, Congress declared war on May 13. On December 22, 1847, Representative Abraham Lincoln introduced this resolution calling for an investigation of the “spot” where U.S. and Mexican forces had allegedly first clashed.
