On April 3, 1860, the first Pony Express mail, traveling by horse and rider relay teams, simultaneously leaves St. Joseph, Missouri, and Sacramento, California. Ten days later, on April 13, the westbound rider and mail packet completed the approximately 1,800-mile journey and arrived in Sacramento, beating the eastbound packet’s arrival in St. Joseph by two days and setting a new standard for speedy mail delivery. Although ultimately short-lived and unprofitable, the Pony Express captivated America’s imagination and helped win federal aid for a more economical overland postal system. It also contributed to the economy of the towns on its route and served the mail-service needs of the American West in the days before the telegraph or an efficient transcontinental railroad.

By this, he meant that the responsibility for the fighting would be gradually transferred to the South Vietnamese as they became more combat capable. However, Laird emphasized that it would not serve the United States’ purpose to discuss troop withdrawals while the North Vietnamese continued to conduct offensive operations in South Vietnam. Despite Laird’s protestations to the contrary, Nixon’s “Vietnamization” program, as he would announce it in June, did include a series of scheduled U.S. troop withdrawals, the first of the war.
