Dandar was one of the commanders in a horse battalion in Mongolian army during Khalkhiin Gol Battle against Japan's Imperial Army. He never lost a battle and was known as the most feared warrior in the battle field. His success wasn't openly invited by the secret services, since he was never injured and wounded during the battles. Due to personal jealousy of an investigating officer Dandar was persecuted for treason and served rest of his life in war camp alone with the very enemies he fought to protect his country.—Delberbayar Purevdorj
