For the next few years the area remained unoccupied by Americans except for travelers and traders. Then the U.S. Army, in an attempt to deceive Confederate spies active in southern California in 1864, falsely publicized that it reclaimed the fort and had renamed it Fort Baker, briefly recalling the area to national attention. After the end of the war in 1865, Octavius Gass, with a commission from the federal government, re-occupied the fort. The Paiute nation had declined in numbers and negotiated a new treaty with the United States, ceding the area around the fort to the United States in return for relocation and supplies of food and farming equipment. Consequently, Gass started irrigating the old fields and renamed the area 'Las Vegas Rancho.' Gass made wine at his ranch and Las Vegas became known as the best stop on the Old Spanish Trail. In 1881, because of mismanagement and intrigue with a Mormon syndicate, Gass lost his ranch to Archibald Stewart to pay off a lien Stewart had on the property. In 1884, Archibald's wife, Helen J. Stewart became the Las Vegas Postmaster.
