The military campaign and subsequent conquest swept across a massive stretch of territory, completely devastating the regions located east of the Jordan River. This vast expanse encompassed the entire land of Gilead, an area originally settled as the tribal inheritance of Gad, Reuben, and Manasseh. The destruction spanned the full length of this eastern territory, sweeping from south to north. The southern boundary of the attack began at Aroer near the Arnon River, facing toward Moab. From that starting point, the devastation spread northward across the entire landscape, eventually reaching the northernmost districts, including Bashan.
The conquest was entirely comprehensive, targeting both the rural lands and the urban centers. While the broader geographical region of Gilead was overrun, the invading forces also specifically targeted the city of Gilead itself. This city acted as the central capital for the surrounding area. The distinction highlights the full scale of the defeat, showing that the invasion did not merely ravage the open countryside, but successfully brought down the region's primary city [מצודת דוד].
