gunboats Jiansheng and Fusheng and the small paddle steamer Yixin were deployed on the northwest curve of the river, between the French ships and the Foochow Navy Yard. A little behind them lay the unarmed transports Yongbao and Chenhang, anchored just off the dockyard. The role of this northern group of ships was obviously to prevent the French from attacking the Navy Yard. Meanwhile, the armed wooden transports Ji'an and Feiyun and the wooden gunboat Zhenwei lay downstream of the French squadron, dangerously isolated on the southwesterly leg of the river, in front of the Customs building. Their job seems to have been to protect the Customs building and to block Courbet's exit from the Min River. Courbet's plan provided for overwhelming firepower to be deployed against the Chinese fleet. He had noticed that the Chinese ships swung with the tide, and determined to make his attack just before the top of the tide at 2:00 pm on the following afternoon, Saturday 23 August, when with luck the Chinese ships would have swung away from the French ships and would be presenting their vulnerable sterns to the attackers. This timing was also important for another reason. If Triomphante successfully ascended the Min River, it was about then that she would be making her appearance. Assuming that the Chinese fleet did not change its position, Courbet's orders provided for the French ships to be at action stations at 1:45 pm and to go into action at around 2:00 pm, on his signal. The battle would begin with an attack by Torpedo Boats No. 45 and No. 46 on Yangwu and Fupo. This attack would be supported by cannon and rifle fire from Volta. Volta would then concentrate on destroying a line of war junks and fireships drawn up just to the west of Losing Island. Once the attack by the torpedo boats had cleared the way, the gunboats Aspic, Vipère and Lynx would sail upriver towards the Navy Yard and take on the other ships of the Chinese northern group. Four steam launches under the command of lieutenant de vaisseau Augustin Boué de Lapeyrère, the future French admiral, were given the job of protecting Volta and the three French gunboats from attack by the Chinese mineboats. To the east Duguay-Trouin, Villars and d'Estaing were to reduce the three ships of the Chinese southern group, to engage the war junks from the
