March 9 in Military History — On This Day

Siege of Veracruz

General Winfield Scott executed the largest amphibious operation in American history to that date, landing 12,000 troops on the beaches south of Veracruz and laying siege to the heavily fortified port city. Naval bombardment and army siege artillery systematically reduced the city's defenses. After three weeks, the garrison of Veracruz surrendered, giving Scott a vital base of operations and supply port for his advance toward Mexico City.

The capture of Veracruz opened the National Highway to Mexico City and demonstrated American capability for large-scale combined arms operations. Robert E. Lee served as an engineer officer here, beginning to earn the reputation for bold reconnaissance that would define his career. The siege established Scott's campaign as the war-winning strategic thrust.

Monitor vs. Virginia — World's First Ironclad Battle

The Union's newly arrived USS Monitor battled the CSS Virginia (Merrimack) in history's first fight between armored warships. Neither vessel could penetrate the other's armor, and after four hours both withdrew. It was a tactical draw but a strategic Union victory.

The battle made every wooden warship obsolete and launched a global arms race in ironclad construction that transformed naval warfare permanently.

Outcome

Draw — neither ship sunk; Virginia never threatens Union fleet again

Raid on Columbus, New Mexico

Before dawn on March 9, 1916, approximately 500 Villista raiders crossed the U.S. border and attacked the small town of Columbus, New Mexico, and the adjacent Camp Furlong military base. They burned the Commercial Hotel, looted stores, and engaged in a gun battle with the 13th Cavalry Regiment. When the fighting ended, 18 Americans were dead (10 civilians, 8 soldiers) and approximately 90–170 Villistas had been killed or wounded. Villa's motivation remains debated: revenge for American arms dealers who took his money without delivering weapons, fury at Wilson's recognition of Carranza, or a calculated provocation designed to draw the U.S. into Mexico and destabilize Carranza.

The Columbus raid was the only attack on continental American soil by a foreign military force between the War of 1812 and 9/11. It provoked the Punitive Expedition, tested the limits of U.S.-Mexico relations, and set the stage for Pershing's humiliating failure — actually enhancing Villa's legend rather than destroying it.
