Yichang (), alternatively romanized as Ichang, is a prefecture-level city located in western Hubei province, China. It is the third largest city in the province after the capital, Wuhan and the prefecture-level city Xiangyang, by urban population. The Three Gorges Dam is located within its administrative area, in Yiling District. History In ancient times Yichang was known as Yiling. Historical records indicate that in the year 278 BC, during the Warring States period, the Qin general Bai Qi set fire to Yiling. In 222 AD Yichang was also the site of the Battle of Yiling, during the Three Kingdoms Period. Under the Qing Guangxu Emperor, Yichang was opened to foreign commerce as a trading port after the Qing and Great Britain agreed to the Chefoo Convention, which was signed by Sir Thomas Wade and Li Hongzhang in Chefoo on 21 August 1876. The imperial government set up a navigation company there and began building facilities. Since 1949, more than 50 wharves (with a total combined length of over ) have been constructed at the port. During the Second Sino-Japanese War, Yichang was a primary supply depot for the defending Chinese army. In October 1938, as the Japanese moved up the Yangtze River towards the strategic city of Chongqing, it became clear that Yichang needed to be evacuated. In 40 days, under the direction of businessman Lu Zuofu, more than 100,000 tons of equipment and 30,000 personnel were transported upstream by steamship or by porters pulling smaller vessels through the Three Gorges rapids to Chongqing. In 1940, the Battle of Zaoyang-Yichang took place in the area.
