Zinn's inclusion of this chapter in order to describe the time period of the Mexican-American War was in order to show the true reality behind it. The fact that the United States gave Mexico no choice but to begin the war. At the same time Zinn uses this to show the negative feelings towards the war that spread throughout the United States. William Lloyd Garrison declared his wishes for the defeat of General Scott's army, in The Liberator, stating “We wish him and his troops no bodily harm, but the most utter defeat and disgrace.” At the same time Reverend Francis Wayland said that only wars of self-defense were just, and in case of unjust war, the individual was morally obliged to resist it and lend no money to the government to support it. Desertion rates in the army also grew rapidly due to the fact that the soldiers, “did not like the army, they did not like the war, and generally speaking they did not like Mexico or the Mexicans.” At the end the glory of the victory was more for the President and the generals, than the soldiers, the dead, or the wounded. In the end through the Treaty of Guadalupe Hidalgo, the Texas boundary was set at the Rio Grande, and New Mexico and California were ceded.
The Mexican-American War is an example of a compromise of the noble intentions of the American people by slavery, poverty, and war. Right from the beginning Mexico is pushed into an unnecessary war by President Polk, due to his desire for U.S expansion. Due to Polk's decision hundreds of lives were lost which were unnecessary and could have been avoided. The American Anti-Slavery Society stated that war was “waged solely for the detestable and horrible purpose of extending and perpetuating American slavery throughout the vast territory of Mexico.” After the end of the war though immense fortunes were made by speculators from the poor soldiers who were desperate for money and were forced into selling the 160 acres of land promised them for less than $50.
