In 1862 the California Column volunteers who fought at Stanwix Station and Picacho Pass fought at the Battle of Apache Pass against 500 Apaches. The battle is considered part of the American Civil War. There were also several engagements between Apaches and Confederates. The Battle of Dragoon Springs marks the only known Confederate combat deaths in the modern confines of Arizona. Other engagements include the Siege of Tubac, the Battle of Cookes Canyon, the Battle of the Florida Mountains, the Battle of Pinos Altos and a number of other smaller skirmishes and massacres.
