Then the duelists took position again; a small stream of blood was flowing down the side of the injured man's head, and over his shoulder and down his body to the floor, but he did not seem to mind this. The word was given, and they plunged at each other as fiercely as before; once more the blows rained and rattled and flashed; every few moments the quick-eyed seconds would notice that a sword was bent—then they called "Halt!" struck up the contending weapons, and an assisting student straightened the bent one.
The wonderful turmoil went on—presently a bright spark sprung from a blade, and that blade, broken in several pieces, sent one of its fragments flying to the ceiling. A new sword was provided, and the fight proceeded. The exercise was tremendous, of course, and in time the fighters began to show great fatigue. They were allowed to rest a moment, every little while; they got other rests by wounding each other, for then they could sit down while the doctor applied the lint and bandages. The law is that the battle must continue fifteen minutes if the men can hold out; and as the pauses do not count, this duel was protracted to twenty or thirty minutes, I judged. At last it was decided that the men were too much wearied to do battle longer. They were led away drenched with crimson from head to foot. That was a good fight, but it could not count, partly because it did not last the lawful fifteen minutes, (of actual fighting,) and partly because neither man was disabled by his wounds. It was a drawn battle, and corps-law requires that drawn battles shall be re-fought as soon as the adversaries are well of their hurts.
During the conflict, I had talked a little, now and then, with a young gentleman of the white cap corps and he had mentioned that he was to fight next,—and had also pointed out his challenger, a young gentleman who was leaning against the opposite wall smoking a cigarette and restfully observing the duel then in progress.
My acquaintanceship with a party to the coming contest had the effect of giving me a kind of personal interest in it; I naturally wished he might win, and it was the reverse of pleasant to learn that he probably would not, because although he was a notable swordsman, the challenger was held to be his superior.
The duel presently began and in the same furious way which had marked the previous one. I stood close by, but could not tell which blows told and which did not, they fell and vanished so like flashes of light. They all seemed to tell; the swords always bent over the opponents' heads, from the forehead back over the crown, and seemed to touch, all the way; but it was not so,—a protecting blade, invisible to me, was always interposed between. At the end of ten seconds each man had struck twelve or fifteen blows, and warded off twelve or fifteen, and no harm done; then a sword became disabled, and a short rest followed whilst a new one was brought. Early in the next round the white corps student got an ugly wound on the side of his head and gave his opponent one like it. In the third round the latter received another bad wound in the head, and the former had his under-lip divided. After that, the white corps student gave many severe wounds, but got none of consequence in return. At the end of five minutes from the beginning of the duel the surgeon stopped it; the challenging party had suffered such injuries that any addition to them might be dangerous. These injuries were a fearful spectacle, but are better left undescribed. So, against expectation, my acquaintance was the victor.
