An important reason for its creation was also securing cheap labour for selected industries, mainly mining and construction. They were also a tool of persecution and work exploitation of politically uncomfortable persons and class enemies. These included intellectuals, commoners, noblemen and members of the clergy. The functioning of the Technical Auxiliary Battalions was not legally covered by the Czechoslovakian laws in force and by international law. Uniforms of members of these camps had black shoulder boards, so they were colloquially called and known as the “Black Barons”. Although formally assigned to the military, they were not allowed to carry weapons. Instead, they had to do dangerous work in mines or factories. They received no significant remuneration, were treated more like slaves and ruined their health. A number of Czech and Slovak sportsmen, who were labelled as the „unreliable“, also worked, as the “Black Barons”, at constructions projects. Approximately 60,000 Czechoslovak citizens were conscripted to the Technical Auxiliary Battalions, of which "some 400" lost their lives. They worked in the coal mines, in the construction industry, on military constructions, in military forests, quarries and agriculture.
Dissolution
The last four of the more than 20 camps were dissolved in 1954. The facilities were also supervised by foreign intelligence services. For example, the CIA describes how the 57th Technical Auxiliary Battalion in Smeč no was converted into a Technical Battalion in 1954. As a result, the situation of the former coercive members changed significantly: they received new clothes, were armed as regular members of the army and henceforth had a two-year military service instead of an indefinite duration. Those who had already completed two or more years were immediately demobilized.
Commemoration
Miloslav Švandrlík's novel "Černí baroni", published in 1969 and filmed in 1992 as a film with the same name and in 2004 as a series, provided a lasting memory on a broad scale. The Švandrlík's novel describes situation in the Technical Battalions, not in the Technical Auxiliary Battalions, where the regime has been completely different. In addition, there are also occasional memorial stones. This also applies to the town of Libavá, which was a military settlement on the Libavá military training area until the end of 2015. On a square in the center of the village, a memorial stone commemorates the members of the Technical Auxiliary Battalions.
