The bulk of the fighting against the Mujahideen was done by the HVO in and around Vitez, Travnik, Bugojno, and Hercegovina.
There's this Scottish mercenary, John MacPhee, who fought with the HVO and Croat Special Forces in Bosnia and he describes a massacre of Croat civilians in Gornji Vakuf. Was the massacre done by Mujahideens, Bosnian Muslims or both? Because in his rage after seeing what the Muslims did, he brutally kills the first 2 Bosnian soldiers there he finds. I wondered if those soldiers had anything to do with the slaughter of the Croats - including babies - or if he was killing Bosniaks out of rage for what foreign Muslims had done.
