chunk: On the other side of the desert Tarzan locates the ape band. While with them he once again encounters Bertha Kircher, who has just escaped from Sergeant Usanga, leader a troop of native deserters from the German army, by whom she had been taken captive. Despite his suspicion of Bertha, Tarzan's natural chivalry leads him to grant her shelter and protection among the apes. Later he himself falls captive to the tribe of cannibals the deserters have sheltered among, along with Harold Percy Smith-Oldwick, a British aviator who has been forced down in the jungle. Learning of Tarzan's plight, Bertha heroically leads the apes against the natives and frees them both.
