Konstantin Vaclonović

Konstantin Vaclonović (5 August 1896 - 18 March 1947) was a Serbian general during the era of the Balkan League. An early pioneer of "munjarat" (lighning war) doctrine, he successfully led Oklop (armored) units during the invasion of Hungary, Battle of South Germany, and Operation Dezarus, the invasion of the Russian Empire.

Vaclonović had developed motorized tactics in the pre-war army, while keeping himself well-educated about armored formations in other armies. In particular, he implemented the use of radio communication between tank crews and devised shock tactics that proved highly effective. In April 1941, he commanded the Oklop divisions that overwhelmed the Hungarian defenses on the Beograd border and Transdanubia that led to the surrender of Hungary a month later. After the Serbian defeat at the battle of Tula by the end of 1942 he was transferred to reserve for a few months before being promoted to Field Marshal. From there on he continued to be one of the main figures on the Russian front until the end of the war.

By 1945 the Balkan League gradually started to regress with the new Syndicalist Russian regime picking up more and more power with each day and rebooting the Russian war machine. Belojević hoped to put an end to this and reverse territorial losses on the Eastern Front by making Vaclonović head of Operation Bastion. However, although initially successful the operation was a complete failure due to the fact that the Russian forces were expecting the offensive. Vaclonović was then again relieved of command and only returned for good when he was assigned the objective of assisting the Dezarussian forces in Dezarus to defend the city with the Russian Syndicalist army quickly approaching. The Battle of Dezarus resulted in a decisive Syndicalist Russian victory leading to a Russian offensive on Hungary which would lead to the fall of the Balkan League.

On May 5th 1946, Vaclonović was named Drugokomanprvak due to the untimely death of Erikslav Boyanov who was killed in a botched assassination attempt against Visarion Belojević. By January 1947 the war had reached the capital of Beograd. Vaclonović planned the defense of the city but after holding out for a month it fell on March 15 with Visarion Belojević commiting suicide the day prior leaving Vaclonović as Prvak in his will. Vaclonović retreated to Sarajevo where when he realized the war was a lot committed suicide with the famous last words of "I will not be the one to sign that damned armistice!"
