On July 7, 1937, the Japanese attack Wanping on the outskirts of Beijing, and the second Sino-Japanese War begins. The Japanese quickly take Beijing and capture Tianjin (Tientsin). Savage fighting breaks out in Shanghai on August 13, which falls to Japan by late December. Initially, Japan continues a policy of open immigration to Shanghai. The November Pogrom (November 9, 1938) in Germany dramatically increases the number of German Jews entering Shanghai. Over 1,500 refugees arrive by the end of December 1938, and the number reaches 4,000 three months later.
