The Battle of the Pinal Mountains was one of many small battles to occurr between Apache warriors and Spanish colonists. The exact date of the battle is unknown but did happen on one day in mid June, 1788 in the Pinal Mountains of southern Arizona, United States .

Beginning on May 31, 1788 to June 24, Captain Romero of the Spanish Army led a 208 man force of Sonoran troops that killed eleven Apache warriors and four women, children and captured thirty-four Apache men and women. The Apaches slain included a chieftain named Quilcho.

Romero's expedition would recover two captive Pimas from Tucson and eleven animals with a loss of two men dead. The so-called highlight of this offensive was a battle in the Pinal Mountains. Ensign Joeseph Moraga with a about ten men from their pack-train escort decided to scout ahead of the wagon train. After scouting a little while in the extreme front, on horseback, the force spotted and attacked a ranchería, protected by "no more than 100 enemies". After Moraga slayed one Apache himself in hand-to-hand combat. Captain Romero, commanding the main force, heard the firing and raced to the scene, arriving just before the battle ended but not before skirmishing a bit first.

The Spaniards lost 1 man, but killed 6 Apache warriors,

Captain Romero evidently left straightaway after the expedition ended to report to the commandant of arms in Arizpe how well he succeeded in his sweep across Apacheria, sothe King of Spain granted Romero a commision. On June 30, a band of Apaches caught and killed him on the hill of San Borja.

Between Chinapa and Bacoachi. Thus, Romero did not live to see the king's commission granting him 2,400 pesos salary. Romero left a widow, Doña Luisa Bohorquez, and at least two sons. The Apache wars against Spain continued on.
