Operation Belt (Polish Akcja Taśma) was one of the large-scale anti-Nazi operations of the Armia Krajowa Kedyw during World War II. In August 1943 the headquarters of the Armia Krajowa ordered Kedyw to prepare an armed action against German border guarding stations on the frontier between the General Government and the territories annexed by the Third Reich. By February 1944, 13 German outposts were destroyed with few losses on the Polish side. One of the Poles who died in the operation was the boy scout Tadeusz Zawadzki Zośka, one of the most important personalities of the Polish underground. Zawadzki was killed on August 20, 1943, during an attack on a German border station at the village of Sieczychy, near Wyszkow.
