During construction, the North Wangtong batteries fired during much of the night but their shots passed mostly above the site and slackened towards 2:00 am. At daylight on 26 February, the three howitzers fired shells and rockets into North Wangtong and occasionally into Anunghoy. British troops were ordered to be ready at 7:00 am, but due to calm weather, the operation was delayed until 11:00 am, when the breeze was strong enough to sail. Anunghoy's defences were the 42-gun South Anunghoy Fort (Weiyuan), the 60-gun Jingyuan Fort north of Weiyuan, and the 40-gun North Anunghoy Fort (Zhenyuan). Captain Humphrey Fleming Senhouse of the "Blenheim"—aided by the "Melville", the steamer "Queen", and four rocket boats—approached the southern fort, dropped its anchor away, and fired broadsides from its starboard guns. The "Melville" approached five minutes later off the portside of the "Blenheim", sailed within of the fort, and fired broadsides in quick succession. A British officer wrote: "The firing of these ships was most splendid: nothing could withstand their deadly aim ... One or two shot were sufficient for the 'dragon-hearted' defenders of the north fort, who, 'letting' off their guns, fled up the hills." At 1:20 pm, after bombarding and silencing the forts, Senhouse landed on the southern battery with about 300 Royal Marines and bluejackets (sailors) carrying small arms to clear out the few remaining defenders. The same was done to the other two batteries. By 1:30 pm, the forts were captured. Chinese Admiral Guan Tianpei was among the estimated 250 killed or wounded in Anunghoy. After his family identified his body the next day, the "Blenheim" fired a minute-gun salute in his honour as his body was taken away. A Chinese bell that Senhouse captured was later sent to England and donated to St Mary's Church in Gosforth by his widow in 1844. North Wangtong's defences were the Wangtong Fort (Hengdang) on the eastern side and the 40-gun Yong'an Fort on the western side, flanked by a field work of 17 guns. A boom connected South Wangtong to the South Anunghoy Fort, where it was heaved or lowered by a windlass.
