With the execution of the Treaty of Guadalupe Hidalgo, the Mexican-American War had come to an end. The territory that Mexico relinquished to America held “some ninety thousand Hispanics and a considerably larger number of tribal Indians,” despite President James Polk characterizing the territory as “almost unoccupied.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 809.
The Treaty of Guadalupe Hidalgo was the culmination of the Mexican-American War and “embodied the objectives for which [President James] Polk had gone to war.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 808.
Throughout the course of the Mexican-American War, General Winfield Scott was increasingly becoming a hero to Americans. While many Americans looked at Scott’s actions and could only admire him, one man took action to ensure Scott would not have a pristine reputation. That man was President James Polk.
Winfield Scott was “one of the greatest soldiers the United States Army has ever produced,” fighting in the War of 1812, the Mexican-American War, and the Civil War. Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 778.
With the Mexican-American War well underway, the midterm elections in 1846-47 were bound to be consequential.
President James Polk, expecting a fast resolution to the Mexican-American War, “requested from Congress in August 1846 a $2 million appropriation for ‘defraying any extraordinary expenses which may be incurred in the intercourse between the United States and foreign nations.'” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 766 quoting James Polk, Diary, II, 76-77 (Aug. 10, 1846). Shortly after Congress followed this instruction and drafted a bill, David Wilmot of Pennsylvania introduced an amendment to specify that slavery would not be lawful in any territory acquired. See Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 767.
Amidst the Mexican-American War, a conspiracy emerged involving President James Polk and the exiled leader of Mexico, Santa Anna. Not only would this conspiracy embolden Whigs but Democrats would also come down on President Polk for his actions.
Some Americans may suppose that during wartime, partisanship declines and a sense of unity prevails. During the Mexican-American War, this was not the case. The Whigs were vocal in their disagreement with President James Polk and the Democrats.
Upon America’s declaring war with Mexico in May 1846, President James Polk sent “the Army of the West” to New Mexico. See Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 758. This army was sent for the sole purpose of conquest, and it was led by Brigadier General Stephen Watts Kearny. Id.
President James Polk, prior to the beginning of the Mexican-American War, had an idea for how to gain new territory for America. He was not going to limit the acquisitions solely to what could be gained with Mexico through military conflict south of Texas. He had his eyes on California and New Mexico, and he had a plan for how to get those two territories.
