On 12 October Yinchang was ordered to take two Beiyang Army divisions (the First Army) down the Beijing-Hankou Railway to suppress the uprising at Wuchang. He attacked the revolutionary army commanded by Huang Xing on 27 October. Covered by their own field artillery and the guns of the imperial fleet, the Beiyang infantry attacked with a cloud of skirmishers followed by a line of close-order company fronts. These textbook tactics were soon to be discredited in the intense fighting of the First World War, but against an undisciplined revolutionary force with no machine guns, they worked perfectly.
