Tajna Organizacja Wojsowa (TOW) or "Secret Military Organization", was the name given to a underground group, or groups, which was supposed to be formed in Poland in the case Polish territory was occupied by foreign powers. The main, country wide, organization was active in the early days of World War II and during the Nazi occupation of Poland, while some of the offshoots or independently organized local "TOWs", such as Tajna Organizacja Wojskowa Gryf Pomorski ("TOW Pomeranian Griffin") or Tajna Organizacja Wojskowa Gryf Kaszubski ("TOW Kaszubian Griffin") were active throughout the whole of the German occupation.
