Several groups led by Baba Faja Martaneshi, former gendarmerie officer Gani bej Kryeziu, a communist Mustafa Gjinishi, and a rightist politician Muharrem Bajraktari. An attempt to unite those groups in one organization was undertaken by Major Abaz Kupi, by now a democratic politician, who created an underground organisation called the Unity Front. This front, which increased in numbers within several months, was crushed in April 1941 after the defeat of Yugoslavia and Greece. Some of its members passed over to the collaborationist camp, some were arrested, and some others fled to the mountains. The warfare ceased for a while.
