Shots at the Marco Polo Bridge near Peking on the night of 7–8 July 1937 began the full-scale Sino-Japanese War, which some historians regard as the beginning of the Second World War. The Japanese quickly took Peking and Tientsin, captured Shanghai after three months of bloody fighting and in December took Nanking, where they committed mass atrocities. Giving ground, the Chinese won the Battle of Taierzhuang and moved their government deep into the interior, turning the war into a war of attrition that tied Japan down until 1945.
