Aleksandar "Aca" Mišić (Serbian: Александар Аца Мишић; 17 June 1891 – 17 December 1941) was a Royal Serbian Army officer in World War I and a Chetnik in World War II.[1]
During World War II, Mišić was complicit in handover of 365 captured Yugoslav Partisans to the Germans.[2] Mišić was captured during Operation Mihailovic by the Germans and executed on 17 December 1941. In December 2016, Serbian pro-Chetnik publicist Miloslav Samardžić of Pogledi published an article stating that Mišić may have actually died in 1944 and not in 1941.[3]
