I agreed that the Germans committed war crimes by executing disproportionate number of Italians captured in Cephalonia.
Actually the crux of the problem that resulted in the execution of the Italians in Cephalonia was the unclear orders of Pietro Badoglio to the Italian forces in Aegean right after the 1943 armistice. In fact it was Badoglio who originally designated Italian forces in Greece and the Aegean under the operational command of the Wehrmacht in Greece, resulting that the Germans treating any Italian forces who resist as mutineers rather as Allied forces (which is technically true since Italian goverment under Badoglio only signed the armistice with the Allies - NOT joining the Allied coalition) which is punishable by death.
Also, I read that General Gandin and some of the senior Division Acqui staff who were captured and were executed AFTER a court-martial by German forces. Does anyone able to access those court martial records in Bundesarchiv?
