On the evening of 19 October, von Bischofhausen again met with König and was told that the original proposal was to be implemented the following day in order to collect the 2,300 hostages. The following evening, the male Jews and communists, who had been held without food since their arrest, were shot by German troops at the barracks and courtyard where they were being held. Simultaneously, males between the ages of 16 and 60 were arrested within Kragujevac itself. They were detained in the barracks of a former motorised battalion at Stanovija Field. Over 7,000 hostages were assembled. German troops and ethnic German units from the Banat were involved in the round-up, as was the 5th Regiment of the SDK, under the command of Marisav Petrović. According to von Bischofhausen, König permitted several classes of males to be excluded from the round-up, including those with a special pass issued by von Bischofhausen's district headquarters, members of a vital profession or trade, and those who were members of Ljotić's movement. When too few adult males could be located, high school students were also rounded up. Also seized were priests and monks from the city's churches. Each hostage was registered and his belongings noted meticulously.
