Port of Shanghai
After the Battle of Shanghai had broken out in August 1937, "President Hoover" was diverted from Hong Kong to evacuate US nationals from Shanghai. On 30 August the liner was moored in the Yangtze River, awaiting clearance to enter the Wusong River to reach the Port of Shanghai when, despite a -long US flag draped on her top deck abaft the bridge to identify her to aircraft as a neutral US ship, the Republic of China Air Force mistook her for the Japanese troopship "Asama Maru" and bombed her.
