 Meanwhile, after an ineffective naval bombardment on 2October, Admiral Lespès attacked the Chinese defences at Tamsui with 600 sailors from his squadron's landing companies on 8October, and was decisively repulsed by forces under the command of the Fujianese general Sun Kaihua (孫開華).The French were now committed to a prolonged Keelung Campaign, and Courbet's squadron was tied down in a largely ineffective blockade of Formosa.After several months of inactivity, Courbet won a series of victories in the spring of 1885.
