It is not clear when the two-fingers salute appeared in Polish military forces. Some see its origin in Tadeusz Kościuszko's 1794 . Others state that it came from Polish soldiers in the Congress Kingdom army around 1815 (partitioned Poland). At that time, the Tsar's Viceroy in Poland, Grand Duke Constantine, said that Poles would salute him with two fingers and use the other two to hold a stone to throw at him. Another legend attributes the salute to the remembrance of Battle of Olszynka Grochowska in 1831, when a soldier, who had lost in the battle all his fingers but the middle and index ones, saluted his superior with the wounded hand and died after it.
