The Battle of Sihang Warehouse took place from October 26 to November 1, 1937, and marked the beginning of the end of the three-month Battle of Shanghai in the opening phase of the Second Sino-Japanese War. Defenders of the warehouse held out against numerous waves of Japanese forces and covered Chinese forces retreating west during the Battle of Shanghai.

The Battle of Shanghai was a large urban battle between the Empire of Japan and the Republic of China in the Chinese city of Shanghai during the Second Sino-Japanese War. It lasted from August 13, 1937, to November 26, 1937, and was arguably the single largest and longest battle of the entire war, with it even regarded by some historians as the first battle of World War II. It resulted in the Japanese capturing the city and heavy destruction to the city.
