My War Memories, 1914-1918 measures were now taken for the demolition of the German railways and mines in the frontier districts. The G.O.C. of the 6th Corps district, in response to rny request, had approached several mining experts in his province, and asked their advice as to the best method of destroying the mines in Upper Silesia.
