In "War of a Thousand Deserts: Indian Raids and the U.S.-Mexican War" by Brian DeLay, the author delves into the brutal raids launched by Comanche warriors on Mexican territory, shedding light on their contribution to igniting the U.S.-Mexican War. Despite their once formidable prowess, the Comanche found themselves weakened by displacement, disease, and encroachment by American settlers. Seeking aid from Mexico proved futile due to the country's own struggles post-independence. As Comanche raids intensified, Mexico's response faltered, emboldening U.S. President James K. Polk to initiate conflict. However, Polk's expectation of easy territorial acquisition clashed with Mexico's fierce resistance driven by national pride. DeLay argues that Polk misinterpreted the situation, highlighting the complex interplay of factors leading to war. The book underscores the significant role of Native American tribes in shaping key events in American history.
