A few curt words from him placed de Rochelle on the defensive. An instance later, however, Heinecke had taken his glove and struck de Rochelle across the face. Taking Sana’s arm he walked off, leaving the furious de Rochelle, whose face had turned to ashen gray, to cry, “You will meet me?” Heinecke turned, drew himself up to full height and with a stiff bow, retorted, “I am at your service!” The next morning, before Heinecke had arisen, a knock was heard at his door. The seconds of de Rochelle were announced. They had come to inform him that de Rochelle was the insulted one and that he was exercising his privilege of choosing weapons. He had decided upon pistols, shots to be exchanged until one or the other fell. Had Heinecke the option he would have chosen the sabre of his student days, that being his favorite weapon. However, he was not afraid. His army training had taught him the use of a pistol, and in his heart he was sure that this affair would certainly win Sana. Sana, however, on hearing of the coming duel, sought Heinecke and begged him to desist, saying “de Rochelle is an expert in the use of a pistol. I have seen him sever a telephone cord at twenty paces and hit a plum I had thrown into the air.” To which entreaties Heinecke replied, with a shrug of his shoulders, “This is an affair of honor.” The next morning, the two duelists, with their seconds and a doctor, went to a secluded section of the Black Forest, about an hour’s ride from the resort. The day was bright and the cleared spot in the forest, where blood would flow and probably a life be sacrificed, had been well chosen by the seconds the preceding day. The preliminaries over, the two men took their stand, facing each other at fifteen paces. Pistols were leveled. They awaited the word to fire--Heinecke cool and determined, de Rochelle perhaps equally determined but rather shaky, having spent the previous evening drinking champagne in celebration of the coming duel. Sana was up before daybreak that morning. When Heinecke left, she followed in an automobile, at a distance, so as not to arouse suspicion. At a road crossing she had lost track of Heinecke’s car, but shortly afterward discovered it, and another, parked by the roadside. She ordered the chauffeur to stop the car, jumping from it before it had come to a standstill.
