Modern rules of Schlagball
Schlagball (“bat-ball” or “hit-ball”) was once very popular in schools and as an amateur club game in Germany, at one time having an organized national championship. A member of the longball family, an early form was described by Gutsmuths in 1796 as the “German Ballgame;” to this day it is still sometimes called simply Deutschball (“German ball”). Today it is still played by clubs in the lower Rhine and North Sea coastal regions, especially on the Frisian islands of Langeoog and Spiekeroog, as well as in Silesia where it is recognized as the German version of what Polish-speakers call Palant.
Game Concept
Schlagball is a game in which two parties of 6 to 12 players confront one another. The contest is over the right to bat, and the higher score after a fixed playing time. The batting party (after Gutsmuths “the ruling party”) defends the right to bat and the field or catching party (after Gutsmuths “the serving party”) tries to win it. The batting party with their successive batters occupy the hitting crease [Schlagmal] and attempt through hits to bring their runs to the running crease [Laufmal] and back.
The field party (the catchers) occupy the running field [Lauffeld]] and the angled zone [Schrägraum] in any arrangement. The fielders try to catch the struck ball or pick it up, or through passing to encircle the running batters or hit them, or to drive them over the boundaries of the running field, or to throw the back ball into the hitting crease to prevent the opponents from winning further points.
By successful fielding play by the catching party, with each changeover point [Wechselpunkt] in which the field party seizes the right to hit, it becomes the new batting party. In connection with the change of possession of the hitting crease, members of the new catching party can immediately plug [abgeworfen] players of the new batting party.
