The 'Battle of Palo Alto' was the first major
battle of the
Mexican-American War and was fought on
May 8,
1846, on disputed ground five miles (8 km) from the modern-day city of
Brownsville, Texas. A force of some 3,400
Mexican troops (a portion of the ''Army of The North'') led by General
Mariano Arista, with the Diaz de La Vega & Garcia Infantry Brigades (2d Light, 1st, 6th & 10th Line Infantry regiments, Tampico Garda Costa Battalion & Company)& the Torrejon Cavalry Brigade (7th & 8th Line Cavalry, Mexico Light Cavalry Regiments, Presidial Companies & Rancheros Irregular Cavalry) engaged a force of 2,400
United States troops — the so called ''US Army of Observation.''(Right Wing :Col. Twiggs with 5th Infantry (Lt. Col. McIntosh), Ringgold's Light Artillery, 3d Infantry (Capt. Morris), Lt. Churchill's Artillery (2-18 pounders), 4th Infantry (Major Allen)& Captains Ker & May Dragoon Squadrons. Left Wing: Lt. Col. Belknap with Lt. Col. Child's Artillery Battalion (serving as Infantry), and 8th Infantry (Capt. Montgomery)
Background
The battle occurred as a result of Mexican efforts to
besiege a U.S. army installation, "Fort Texas",(Garrison:Major Brown with 7th Infantry, Capt. Loud's Artillery Co.with 4- 18 pounders, & Lt. Bragg's Light Artillery 4guns )which the Mexicans viewed as having been built within the boundaries of Mexican Texas. General
Zachary Taylor, receiving supplies from Port Isabel, heard the distant report of cannon fire. The Mexicans had begun to attack Fort Texas. Taylor gathered his troops and rushed to relieve the defenders of the fort but was intercepted by a Mexican force commanded by General Arista. Another Mexican force (1,540 men, including Artillery 14 Guns, Matamoros Natl. Guards Battalion, Mexico, Puebla & Morelia Activos Battalions) under General Francisco Mejia were left behind at Fort Brown & Matamoros.
Battle
General Arista's army was stretched a mile wide, making an American
bayonet charge impossible. Taylor, in an unlikely move, advanced his artillery to attack the enemy. It was this "Flying Artillery"—the tactic of using light artillery to attack then quickly move to another location and fire once more, developed by
Major Samuel Ringgold—that won the battle for the Americans. The Mexican artillery, heavy and slow, was futile in the thick brush at Palo Alto. Arista ordered
cavalry charges to
flank the artillery gunners, but the American "Flying Artillery" was able to mobilize, relocate, and repel the oncoming dragoons.
Aftermath
Ringgold died of wounds inflicted in the battle, but his death spurred a significant boost to morale across America. After the first day, Taylor arose to find that the Mexicans had withdrawn from the field of battle and moved camp to the site of the next engagement,
Resaca de La Palma.

Engraving memorializing the fatal wounding of Maj. Samuel Ringgold in the battle
Mexicans suffered large casualties compared to the Americans for several reasons. The Mexican army had poorer gunpowder than the Americans, shortening the range of their
cannon and
musket fire. The poor powder had a tendency to explode prematurely and caused many soldiers to pour smaller amounts of gunpowder, further affecting the range of their weapons. Mexican soldiers usually had little training and were often scared of the volatile gunpowder. The Mexicans, as was typical throughout the war, had technologically inferior weaponry to the Americans. The musket Arista's men used was the
British Brown Bess — the same weapon the British had used during the
Napoleonic Wars and
American Revolutionary War a century before.
