The struggle started on September 18, 1931, when Japanese troops began their invasion of northeast China. It was intensified when Japan's full-scale invasion began after a crucial access point to Beijing, Lugou Bridge, also known as Marco Polo Bridge, was attacked by Japanese troops on July 7, 1937.
