The Occupation of Matamoros
May 18, 1846 in Mexico

Following their victories at Palo Alto and Resaca de la Palma (and the subsequent relief of Fort Texas), the American army added to its successes with the bloodless occupation of Matamoros on May 18, 1846, after Arista abandoned the town and withdrew his forces to the relative safety of Monterey, about a hundred miles to the south.
