In May, Commander Charles Henry Davis of the United States Navy, with some marines, received the surrender of William Walker, self-proclaimed president of Nicaragua, who was losing control of the country to forces financed by his former business partner, Cornelius Vanderbilt, and protected his men from the retaliation of native allies who had been fighting Walker. In November and December of the same year United States vessels USS Saratoga, USS Wabash, and Fulton opposed another attempt of William Walker on Nicaragua. Commodore Hiram Paulding's act of landing marines and compelling the removal of Walker to the United States, was tacitly disavowed by Secretary of State Lewis Cass, and Paulding was forced into retirement.[RL30172]
