Second Ruhr

The "second Ruhr" was a World War II area that included the "southern regions of Germany, the plateau of Bohemia, and Silesia" where Nazi Germany military production was dispersed away from Allied bomber bases in England.^[1] After Allied Operation Pointblank bombing of German aircraft facilities had begun, Nazi Germany dispersed the 27 larger aircraft works^[specify] across 729 medium and very small plants (some in tunnels, caves, and mines),^[2] and oil production was also dispersed (e.g., Blechhammer). However, by October 1943, long-range bombers could reach the area^[1] (e.g., Marienburg).

The Tarthun underground production of Heinkel He 162s in Magdeburg was captured in April 1945
