Mexico's 1842 Invasions of Texas: The Battle of Salado Creek

In 1842, Mexico launched multiple military incursions into the Republic of Texas, six years after losing the territory in 1836. Under General Antonio López de Santa Anna, who had returned to power, Mexican forces sought to reclaim Texas. The first invasion in March 1842, led by General Rafael Vasquez with 700 men, briefly occupied San Antonio before withdrawing due to insufficient strength. A second invasion in July was repulsed at Fort Lipantitlan on the Nueces River. The most significant engagement occurred in September 1842, when French-born General Adrian Woll, a veteran of Napoleon's army and Santa Anna's 1836 campaign, led 1,400 men across the Rio Grande and captured San Antonio on September 11. Texian forces under Colonel Matthew Caldwell and Texas Rangers under John Coffee Hays mustered about 200 men at Salado Creek, seven miles from San Antonio. Using a decoy tactic, Hays lured Mexican cavalry into an ambush, leading to a battle where Texian rifles outranged Mexican muskets. Woll withdrew after suffering nearly 60 casualties, though a Texian relief column was massacred by Mexican cavalry in the Dawson Massacre. These incursions were Mexico's last against the Republic; Texas was annexed by the United States in 1845, escalating the border dispute that led to the Mexican-American War.
