Whose family won possession of the disputed land in the lawsuit?

At the beginning of the short story, Saki writes that Ulrich von Gradwitz's grandfather had won possession of the disputed territory and "wrestled it" from the illegal possession of Georg Znaeym's family. The disputed territory is described as being a narrow strip of land with little game. Despite the uselessness of the territory, the two families have been feuding for three generations, and the land dispute has become personal for Ulrich von Gradwitz. Ulrich detests Georg Znaeym, who illegally poaches in the disputed territory and refuses to acknowledge the Court's past decision. At the beginning of the story, Ulrich and his group of men are traveling through the narrow strip of land looking for Georg in hopes of murdering him. Ulrich ends up running into Georg in the middle of the forest and is about to murder him when a severe storm causes a beech tree to fall on both of them.
