In 1773 the Spanish held the country south of Tucson, then called Tulquson. Unwilling to leave the rich silver mines, that brought such treasure to the Church, the priests and Spanish settlers gathered around them in their half religious and half military missions; again and again returned to the country, only to be again driven out by the Apaches, so that more than half the priests sent to Arizona were killed by the Indians. And yet the missions, through the fidelity of the Pima and Papagoes, held their own until the revolution for Mexican independence. From that time forward they languished, until suppressed by a decree of the Mexican government in 1827. In 1824 Sylvester and James Pattie, father and son, from Bardstown, Kentucky, made up a party of one hundred adventurous frontiersmen to trap on the headwaters of the Arkansas. After many adventures in New Mexico the party broke up, and a few of them attempted to cross Arizona to the Pacific. Upon reaching San Diego they were imprisoned, and the father died in prison. Pauline Weaver, of White County, Tennessee, penetrated Arizona as early as 1832. As one of the results of the Mexican War, the portion of Arizona north of the Gila River was ceded to the United States February 2, 1848, and the southern portion acquired by the Gadsen purchase of December 30, 1853. The discovery of gold in California in 1849 made Arizona a highway for the adventurous spirits that pressed across the continent to establish an empire on the Pacific coast. In 1855 the boundary survey was completed by Major Emory and Lieutenant Michler. In August, 1857, a semi-monthly line of stages was put on between San Antonio, Texas, and San Diego, California. This was followed in August, 1858, by the celebrated Butterfield Overland Express, making semi-weekly trips between St. Louis and San Francisco—time twenty-two days. This was run with great regularity until the rebellion in 1861. By act of Congress in 1854 Arizona was attached to New Mexico, and a commissioner appointed to survey the boundary. In 1854 Yuma was laid out under the name of Arizona City. In 1857 a few mining settlements began to spring up in the Mohave country. In 1859 a newspaper was published for a short time at Tubac. The country was nominally a portion of New Mexico, but Santa Fe was far away and the Apaches ruled the land. In 1857 and again in 1860 efforts were made in Congress to secure the establishment of a separate territorial organization. On the 27th of February, 1862, Captain Hunter with a band of one hundred guerrillas reached Tucson and took possession of Arizona for the Confederate government. The miners fled the country. The Apaches fell upon them, murdering many of them by the way. The Mexicans rushed across the border and stripped the mines of their machinery and improvements, and the country was deserted.
