I begin construction of the Siegfried line, the Ludendorff line, and the 2nd Hindenburg line. Each will contain many trenches, machine guns, gun batteries, howitzers, forts, aa batteries, and anti tank guns. The Siegfried line will run from the coast of the North Sea all the way down to the border with Switzerland. The Ludendorff line will run along our northern coast, from Schleswig-Holstein all the way to Königsberg. The 2nd Hindenburg line will go from the Flanders border to the Sudetes.
