Such attacks and counterattacks continued well into late August, when the fall of Baoshan, a vital coastal town, seemed imminent. Chiang Kai-shek ordered the remaining troops of the 98th Division to defend the town. One battalion, under Yao Ziqing (姚子青), was assigned to the task. The situation in Baoshan was grim, as the Japanese had surrounded the town on September 5. However, Yao ordered his men to defend to the death. Japanese artillery strikes reduced the town to rubble, and Yao was killed in house-to-house fighting. On September 6 Baoshan fell. The entire battalion, except for one soldier, was killed in action. The Chinese would continue to sustain this level of casualties throughout the Shanghai campaign.
