Howe recounts General Zachary Taylor’s strategic movements in early May 1846, as the US Army of Occupation faced General Mariano Arista’s Mexican forces near Fort Texas. Despite Taylor’s eventual retreat to protect his supply base at Port Isabel, Arista’s attempt to encircle Taylor’s forces was delayed, leading to a Mexican siege of Fort Texas and blocking Taylor’s return. Ulysses S. Grant, then a young second lieutenant, experienced his first hostile gunfire amidst these events, marking a significant moment in his military career.

The chapter delves into Taylor’s background, his reputation as “Old Rough and Ready” (761), and his longstanding service in the US Army. His adversary, Mariano Arista, is portrayed as a formidable and respected leader, with notable personal and professional connections to the United States.

Despite heavy casualties in the Siege of Fort Texas, neither army gained a decisive victory, but the US forces, particularly the “flying artillery” led by Major Sam Ringgold, demonstrated superior firepower and mobility. This battle marked the beginning of a series of engagements that underscore the technological and tactical superiority of US forces during the Mexican-American War. The Resaca de la Palma battle and the occupation of Matamoros highlight Taylor’s tactical decisions and marked a turning point in the conflict.
