Wyatt and the group he guarded were regarded as claim jumpers and were confronted by armed representatives of the other company. King wrote, "it was the nerviest thing he had ever seen". With guns pulled, Wyatt came out of his tent with a Winchester rifle, firing a round at the feet of Federal Receiver Stafford W. Austin. "Back off or I'll blow you apart, or my name is not Wyatt Earp". The owners summoned the U.S. marshal, who arrested Earp and 27 others, served them with a summons for contempt of court, and sent them home. Earp's actions did not resolve the dispute, which eventually escalated into the "Potash Wars" of the Mojave Desert. On July 23, 1911, Earp was arrested in Los Angeles and charged with attempting to fleece J. Y. Peterson, a realty broker, in a fake faro game. Since money had not changed hands, the charge against Earp was reduced to vagrancy and he was released on $500 bail. The Earps bought a small cottage in Vidal, the only home they ever owned. Beginning in 1911 and until Wyatt's health began to fail in 1928, Wyatt and Sadie Earp summered in Los Angeles and spent the rest of the year in the desert working their claims. The "Happy Days" mine was located in the Whipple Mountains a few miles north of Vidal. Wyatt had some modest success with the Happy Days gold mine, and they lived on the slim proceeds of income from that and oil wells in Oakland and Kern County. In about 1923, Charles Welsh, a retired railroad engineer and friend that Earp had known since Dodge City, frequently invited the Earps to visit his family in San Bernardino. When the Welsh family moved to Los Angeles, the Earps accepted an invitation to stay with them for a while in their top-floor apartment until the Earps found a place to rent. After Earp and Sadie moved into a bungalow nearby, Charlie Welsh's daughter, Grace Spolidora, recalled that Sadie, who had never had many domestic skills, did very little housekeeping or cooking for Wyatt. She and her sister Alma were concerned about the care Sadie gave Wyatt. Though he was at times very ill, she still did not cook for him. Spolidora, her sisters, and her mother brought in meals. While living in Los Angeles, Earp became an unpaid film consultant for several silent cowboy movies. In 1915, Earp visited the set of director Allan Dwan's movie, "The Half-Breed", starring Douglas Fairbanks.
