Battle of Abonito Pass

The Battle of Abonito Pass, the last battle of the Puerto Rican Campaign of the Spanish-American War, was in fact interrupted by news of the August 13 armistice before its outcome could be decided.

On August 12, United States Generals James H. Wilson and Oswald H. Earnst had deployed two brigades along the Spanish defenses between Barranquitas and Cayey, chief of which were the guns at Abonito Pass. Following several successful reconnaissance missions to determine enemy strengths and positions, General Wilson ordered an offensive along the Spanish flank accompanied by heavy artillery bombardment. Met with fierce Spanish resistance and defensive artillery fire, the American attacks collapsed, and Wilson settled the troops for the evening.

Early next morning, before renewed assaults could begin, American commanders received telegraphs informing them of the armistice. The battle for Puerto Rico was over.
