Mongol Second Campaign against Western Xia

Timeline

1. 1226Northern steppe · Mongolian PlateauWestern Xia had previously refused to join the Mongol western campaign, reduced tribute, and detained envoys; Genghis Khan resolved to campaign in person again. He assembled princes, thousand-household units, and vassal forces in the northern steppe, with the strategic goal of fully conquering Western Xia and eliminating concerns for the westward advance.
2. 1226Hetao region · HetaoThe Mongol army advanced south by several routes, first taking key positions in the Hetao to cut off Western Xia's northern shield. The forces swept forts and tribes along the way; Western Xia's border garrisons could not resist, and the eastern gates of the Hexi Corridor fell one after another.
3. 1226Hexi Corridor · Hexi CorridorAdvancing east along the Hexi Corridor, the Mongol army took Ganzhou, Suzhou, and other major towns in succession, collapsing Western Xia's northwestern defense line. The main army then turned southeast, its spearhead aimed at Lingzhou and the capital Zhongxingfu, forcing Western Xia to concentrate its main forces to meet the attack.
