The whole body of pupils was divided into three, afterwards into four sections, each of which had its own citadel. After two had declared war against two others, the battle raged until one party captured the strongholds of the other. This was done as soon as a combatant had set foot on the hearth of a hostile fortress.
The battle itself was fought with stakes blunted at the tops. Every one touched by the weapon of an enemy must declare himself a prisoner. To admit this, whenever it happened, was a point of honour.
In order to keep all the combatants in action, a fourth division was added soon after our arrival, and of course it was necessary to build a strong hold like the others. This consisted of a hut with a stone roof, in which fifteen or twenty boys could easily find room and rest, a strong wall which protected us up to our foreheads, and surrounded the front of the citadel in a semicircle, as well as a large altar-like hearth which rose in the midst of the semicircular space surrounded by the wall.
We built this fortress ourselves, except that our teacher of handicrafts, the sapper Sabum, sometimes gave us a hint. The first thing was to mark out the plan, then with the aid of levers pry the rocks out of the fields, and by means of a two-wheeled cart convey them to the site chosen, fit them neatly together, stuff the interstices with moss, and finally put on a roof made of pine logs which we felled ourselves, earth, moss, and branches.
How quickly we learned to use the plummet, take levels, hew the stone, wield the axes! And what a delight it was when the work was finished and we saw our own building! Perhaps we might not have accomplished it without the sapper, but every boy believed that if he were cast, like Robinson Crusoe, on a desert island, he could build a hut of his own.
As soon as this citadel was completed, preparations for the impending battle were made. The walls and encircling walls of all were prepared, and we were drilled in the use of the poles. This, too, afforded us the utmost pleasure. Touching the head of an enemy was strictly prohibited; yet many a slight wound was given while fighting in the gloom of the woods.
Each of the four Bergwachts had its leader. The captain of the first was director of the whole game, and instead of a lance wore a rapier. I considered it a great honour when this dignity was conferred on me. One of its consequences was that my portrait was sketched by "Old Unger" in the so-called "Bergwacht Book," which contained the likenesses of all my predecessors.
During the summer months all eyes, even as early as Thursday, were watching the weather. When Saturday evening proved pleasant and Barop had given his consent, there was great rejoicing in the institute, and the morning hours must have yielded the teachers little satisfaction.
Directly after dinner everybody seized his pole and the other "Bergwacht" equipments. The alliances were formed under the captain's guidance. We will say that the contest was to begin with the first and third Bergwacht pitted against the second and fourth, and be followed by another, with the first and second against the third and fourth.
We assembled in the court-yard just before sunset. Barop made a little speech, exhorting us to fight steadily, and especially to observe all the rules and yield ourselves captives as soon as an enemy's pole touched us. He never neglected on these occasions to admonish us that, should our native land ever need the armed aid of her sons, we should march to battle as joyously as we now did to the Bergwacht, which was to train us to skill in her defence.
