I was deployed in Afghanistan some years ago, where we shared a camp with some German troops. They used the nickname spieß (spear) for their company sergeant major. We where told that this harkens back when formations of pikemen where still used. The spieß would be standing at the rear of the formation and use his spear to prevent anyone from fleeing thus the name. I've been trying to verify this story without much luck. I was wondering if any of you would be able to succeed where i failed.
This is basically true, but first a clarification. Spieß literally means spit, as in a spit you'd roast veggies on over an open flame. Spear in German is 'speer'.
In the 16th century the sergeant or other non-commissioned officer of mercenary company would stand at the back of the formation, pike in hand and keep men in line. They weren't killing cowards who fled form battle, their role was to keep lines straight and marching at an appropriate pace. Corrections would be dealt out to the lazy or hesitant with a swift poke or prod.
