Ringgold served in General
Zachary Taylor's
occupation force in
Texas as a Major of Artillery. On May 8, 1846, as he and 2,400 troops were en route to Fort Texas, they were engaged at the
Battle of Palo Alto by Mexican General
Mariano Arista and his force of 3,800 men. Arista's army was stretched a mile wide, making an American bayonet charge, Taylor's first option, impossible. Taylor, in an unlikely move, advanced his artillery to attack the enemy. The use of Ringgold's flying artillery tactic won the battle for the Americans. The Mexican artillery, heavy and slow, was futile in the dense Tamaulipan thornscrub brush of 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. During the battle, Ringgold was mortally wounded by cannon fire that mangled both his legs just below the crotch. Nevertheless, he refused to leave the field during the battle. He survived three days, during which time he debriefed on the battle, before dying in
Port Isabel, Texas. He was initially buried in Port Isabel. In December 1846, he was buried in
Green Mount Cemetery in Baltimore. Robert D'Unger, then journalist at the
Baltimore Democrat, claimed that he was the first to report news by telegraph while reporting Ringgold's death. ==Commemoration==
