Partisan 9th Corps
The 9th Corps, in Slovenian IX Korpus, was a unit of the Yugoslavian Liberation Army during World War II, with many division and brigade-size units, operating in Slovenia, Kroatia and Italy, namely Friuli-Venezia Giulia.
This unit took part to many operations against Germans and Italians before and after the surrender of Italy in 8 September 1943; one of the more remarkable was the German Operation Adler, which saw confrontation between German and Fascist Italian armies and some brigades of the Corps.
After a decision of Palmiro Togliatti, all communist units (named Garibaldini after Giuseppe Garibaldi) operating in territories reclaimed by Yugoslavians were to be incorporated into NOVJ (the Popular Yugoslavian Army of Liberation), and wrote personally the content of the order of the day to be adopted by communist partisans.
