Slave work for the A4 rocket (later named V2 by Nazi propaganda)
Aggregate 4, or A4 in short, was the designation of the first fully functional long distance rocket world wide. The rocked had been developed in the army research centre in Peenemünde by a group of scientists under the lead of Wernher von Braun. Propaganda minister Joseph Goebbels later named it Vergeltungswaffe 2 or V2 (vengeance weapon 2). The production was allocated to various sites. Thousands of concentration camp prisoners were used for the production. In the armament plant Vorwerk Mitte in Schmiedebach near Lehesten, rocket engines were tested and rocket fuel produced.
