 The net effect of the Arizona Rangers' actions was to delay the advance of the California Column for over a month, which probably saved the Confederate Army of New Mexico, now retreating back to Mesilla from its defeat at the Battle of Glorietta Pass, from being intercepted and destroyed by the California Column during April 1862.After the battle at Picacho Pass, Captain Hunter wrote to Governor Baylor, requesting a reinforcement of at least 250 men, with which he felt he could hold Tucson.When no reinforcements were forthcoming, Hunter decided to evacuate Tucson.
