In Arizona, the California Volunteer Cavalry retake Tucson without firing a shot
Confederate forces under Colonel Henry H. Sibley had occupied Tucson, Arizona eighty days before. A withdrawal was ordered on May 14, 1862 and six days later elements of the First California Volunteer Cavalry retook the town without firing a shot. Retreating Confederate forces soon reached Texas, ending Sibley's abortive invasion of Arizona. (By John Osborne)
