During this time, King Fisher rarely committed acts of violence or theft against other Texas settlers, instead opting to raid and rustle cattle across the Mexican border. This was a time of massive raids, pillaging, looting, raping, and murder by United States and Mexican bandits. In response to feelings of alleged lack of reprisal or defense by authorities, the Texans formed more groups of bandits. This activity only fueled disputes and ill will from the Mexican side and generated substantial problems for Texas Ranger battalions, who were trying to quell Mexican bandit raids into Texas. The Texas Rangers, under Leander H. McNelly, opposed the Mexican rebel leader Juan Cortina. The Rangers also raided the Fisher Ranch and arrested Fisher. However, he was released after a "gentleman's agreement"' was reached that his cattle rustling into Mexico would end. Pressure from the Texas Rangers caused Fisher to retire from this trade, and he began legitimate ranching.
