National Road Skirmish - Plan del Rio was a Mexican-American War engagement fought in Mexico, 1847.
The Skirmish at Matamoros occurred late in the Mexican-American War as part of a broader campaign to secure U.S. Army lines of communication. A Mexican Army Light Corps detachment under General Joaquín Rea, commanded locally by Colonel Piedras, had been harassing the U.S. Army's supply line along the National Road. General Joseph Lane was tasked with eliminating this threat by striking at the Mexican depot and the forces guarding it.
General Lane executed a night march in the rain from Puebla to reach the outskirts of Izucar de Matamoros early in the morning. Upon arrival, Lane immediately launched a surprise attack on the outpost guards, who fled into the town with U.S. forces-including Texan riflemen and Louisiana Dragoons-in pursuit. The engagement that followed was described as a "short and sanguinary action," which caused the main Mexican force to break and disperse into a forest beyond the town. The speed and decisive nature of the assault achieved complete surprise and tactical victory without cost to the American forces.
The skirmish resulted in a complete U.S. victory with significant strategic and material gains. General Lane secured possession of the town and its depot, capturing three artillery pieces and other supplies. Additionally, 21 American soldiers who had been held captive were freed and re-equipped with captured muskets and horses. The Mexican commander, Colonel Piedras, was killed in the action, along with an estimated 60 to 80 Mexican soldiers killed or wounded. By eliminating this harassment force and seizing the depot, Lane successfully removed a significant obstacle to U.S. supply operations on the National Road during the final stages of the war.
