The German–Yugoslav Partisan negotiations were held between German commanders in the Independent State of Croatia and the Supreme Headquarters of the Yugoslav Partisans in March 1943 during World War II. The negotiations – focused on obtaining a ceasefire and establishing a prisoner exchange – were conducted during the Axis Case White offensive. They were used by the Partisans to delay the Axis forces while the Partisans crossed the Neretva River, and to allow the Partisans to focus on attacking their Chetnik rivals led by Draža Mihailović. The negotiations were accompanied by an informal ceasefire that lasted about six weeks before being called off on orders from Adolf Hitler. The short-term advantage gained by the Partisans through the negotiations was lost when the Axis Case Black offensive was launched in mid-May 1943. Prisoner exchanges, which had been occurring between the Germans and Partisans for some months prior, re-commenced in late 1943 and continued until the end of the war.
