The United States rallied a force of 100 Texas Rangers and 113 allies where the Comanches rallied a force between the range of 200-600. In the battle there were three decisive battles between the Comanches and the Texas Rangers. The first began in the morning of May 12 when the Texas Rangers led by General Ford attacked a Comanche camp, the Comanches were not ready for such attack and a massacre occurred. The second battle began when the Texas Rangers attempted to do the same to the next Comanche camp only to be met by resistance from the Comanche’s who saw the approach of the Texas Rangers. The Comanches at this point were able to act in defense but there was still a significant lose of life for the Comanches. It was not until the third and final battle of Little Robe creek where the Comanche warriors were able to take an offensive stance against the Texas Rangers. However, the end result of the three battles was costly to the Comanche forces: 76 were killed and over 60 were captured by the Texas Rangers. By comparison, the Texas Rangers lost two killed and only five wounded.

 Passage 3:Ronnie Barker and Ronnie Corbett met in 1963 at the Buckstone Club in the Haymarket, London, where Corbett was serving drinks between acting jobs. At the time, Barker was beginning to establish himself as a character actor in the West End and on radio. They were invited by David Frost to appear in his new show, The Frost Report, with John Cleese, but the pair's big break came when they filled in, unprepared and unscripted, for eleven minutes during a technical hitch at a British Academy of Film and Television Arts awards ceremony at the London Palladium in 1970. In the audience was Bill Cotton, the Head of Light Entertainment for the BBC, and Sir Paul Fox, the Controller of BBC1. Cotton was so impressed by the duo that he turned to Fox and asked: "How would you like those two on your network?" Unbeknownst to them the pair had just had the renewal of their contract declined by London Weekend Television of rival network ITV, and so were free to change channels. Barker and Corbett were given their own show by the BBC.
