Liu Mingchuan
On the morning of 5 August, after the Chinese rejected a French ultimatum to hand over their coastal defences, "La Galissonnière", "Villars" and "Lutin" engaged and disabled Keelung's three coastal batteries. Admiral Lespès put a landing force ashore in the afternoon to occupy Keelung and the nearby coal mines at Pei-tao (Pa-tou, 八斗), but the arrival of a large body of Chinese troops led by Liu Mingchuan forced the French to make a fighting withdrawal and re-embark on 6 August. French casualties in this unsuccessful operation were 2 dead and 11 wounded. The Chinese suffered markedly heavier casualties.
