The account of Roosevelt's expedition into the Brazilian jungle in 1913 as a member of the Roosevelt-Rondon Scientific Expedition, co-named after its leader, Brazilian explorer C�ndido Rondon. The expedition was intended to discover if the Rio da D�vida ('River of Doubt'), flowed into the Amazon. During the expedition Roosevelt lost 23 kilos, and felt the effects of the bullet which remained lodged in his chest following the 1912 attempt on his life. He then suffered a leg wound which festered and gave him tropical fever. He planned to commit suicide in order to preserve the expedition, but after entreaties by his son was convinced to continue. Ultimately the expedition was successful and the river was renamed Rio Roosevelt, sometimes Rio Teodoro, in his honour.
