With the success of that expedition a mountaineering club was thus proposed and fronted by Colonel Gerry Finch, Major Hugh Robertson and Second Lieutenant Chris Bonington. On 24 May 1957 the Army Mountaineering Association was formed as a charitable status. Its constitution states that it exists 'To promote military efficiency by encouraging mountaineering in the Army'. Another army officer, Tony Streather ascended the third highest mountain in the world Kangchenjunga in 1955, then Tirich Mir five years later. His legendary parts played on K2 and Haramosh gave him a superb reputation in mountaineering. More army officers led the way - Major Jon Fleming had led AMA expeditions to Tirich Mir in 1969, Lahul in 73 and Nuptse three years later.
