During World War II, under German occupation, the stuffed "Kasztanka" ended up in Warsaw's Museum of the Polish Armed Forces. The mount survived the war, but due to lack of routine care for the collections, was badly damaged by moths. After the war she was probably cremated. By some accounts, this was done at the behest of Marshal Michał Rola-Żymierski, who had opposed Marshal Piłsudski's May 1926 Coup d'État and been court-martialled and demoted from general to private, but during World War II had been restored by the Soviet Union's Marshal Joseph Stalin to the rank of general and on May 3, 1945, promoted to Marshal.
