I have an Eagle cap badge made by fighters of the The Holy Cross Mountains Brigade (Brygada Świętokrzyska) which was a unit of the Polish underground NSZ (Narodowe Siły Zbrojne or National Armed Forces) during World War II, which refused orders to merge with the Home Army in 1944 and operated as a unit of NSZ-ZJ alliance.
