Battle of Beijing-Tianjin
1937 Japanese victory

The Battle of Beijing–Tianjin (25–31 July 1937) was a series of battles of the Second Sino-Japanese War fought in the proximity of Beijing and Tianjin. It resulted in a Japanese victory. With the fall of Beijing and Tianjin, the North China Plain was helpless against the Japanese divisions which occupied it by the end of the year. The Chinese National Revolutionary Army was in constant retreat until the hard fought Battle of Taierzhuang.

Zhang was vilified relentlessly by the Chinese press, and reviled as a traitor. Upon arrival at Nanjing he apologized publicly. Since he later died fighting against the Japanese, the Kuomintang posthumously pardoned Zhang for the events in Beijing.
