First step was to determine whether it was indeed a Serbian soldier in the grave under the wooden cross. An exhumation was conducted by the commission on 23 November 1921. Parts of the grenade are found under the skull, almost as a pillow, while the skeleton had the blown left side of the chest, so it is estimated that he was killed by the Austro-Hungarian howitzer while he was watching from the lookout. He was apparently buried in the crater formed by the explosion of the very grenade that killed him, just below Žrnov. The soldier had no identity badge which suggests that he was either member of the Third Call regiments (with soldiers over 38 years old) or was drafted immediately prior to the battle which is probably correct as  the skeletal remains pointed out to a very young male, no older than 19–20 years. It was said that his skull was "small, like of a boy" and that skeleton was petite, of a boyish, thin stature. Some sources actually claim he was only 15. Based on the other findings in the grave, the commission concluded that the remains do belong to the Serbian soldier and reburied him, with the grenade parts, while his personal belongings were taken to the cabinet of the president of the assembly for safekeeping.
