Here is the main thrust of Neil French’s e-mail: “The German General stuff used to divide officers into four categories: the clever and lazy, the clever and hard-working, the stupid and lazy and the stupid and hard-working. The best Generals, the Germans found, came from the clever and lazy; the best staff officers emerged from the clever and hard-working; the stupid and lazy could be made useful as regimental officers; but the stupid and hard-working were a menace, to be disposed of as soon as possible.”
