On 27 and 28 August the French squadron bombarded and destroyed the Chinese defences at the Jinpai pass near the entrance to the Min River. The Jinpai (金牌) and Changmen (長門) batteries, known to the French as Fort Kimpai and the White Fort (Fort Blanc), were put out of action, and the French also inflicted heavy casualties on a number of Chinese field batteries and infantry formations.
