Many Americans supported the war, but not all of them. Abolitionists opposed the war because they were afraid that the southern states would expand slavery into new land. Some slave owners thought the new territories might ban slavery.

His troops followed the Sante Fe Trail and took the city without a fight in August 1846. The Navy was sent to blockade Mexican ports on the Pacific coast and the Gulf of Mexico.

6. Bear Flag Revolt A small group of American Settlers declared that California was an independent republic. They created a flag to represent themselves as a new republic. The revolt caught the attention of John C. Fremont and he quickly declared that he would conquer California without knowing the United States and Mexico were at war.
