Taishō period Shōwa period The Resistance at Nenjiang Bridge was a small battle fought between forces of the Chinese National Revolutionary Army against the Imperial Japanese Army and collaborationist forces, after the Mukden Incident during the Invasion of Manchuria in 1931, prior to the start of the Second Sino-Japanese War.

In November 1931, the acting governor of Heilongjiang province General Ma Zhanshan chose to disobey the Kuomintang government's ban on further resistance to the Japanese invasion and attempted to prevent Japanese forces from crossing into Heilongjiang province by defending a strategic railway bridge across the Nen River near Jiangqiao.

Eventually, Ma was forced to withdraw his troops in the face of Japanese tanks and artillery.

Although often led by army officers and with numbers of former regular troops among their ranks, most volunteers had no previous military experience.

These irregular armies were to later become the main anti-Japanese force in northeast China during 1932 and posed a serious obstacle to Japanese attempts to pacify the country.
