The Thornton Affair refers to a confrontation that occurred on April 25, 1846, between American and Mexican troops near the Rio Grande, which was then the disputed border between Texas and Mexico. The incident escalated when Mexican forces attacked a U.S. patrol, leading President James K. Polk to declare that "American blood had been shed on American soil." This event was a catalyst for the Mexican-American War, which ultimately resulted in significant territorial gains for the United States. The Thornton Affair highlighted the tensions stemming from U.S. expansionism and the annexation of Texas.
