British and Force warships anchor at the port of Beitang in preparation for the latest landing in China
The latest British and French efforts to force China to abide by the trade treaties of 1858 continued in earnest when Royal Navy and French Navy units carrying an invasion force anchored at Beitang on the mouth of the Hai He River. Troops began to land the following week and the Taku Forts were captured three weeks after that. This led to the Ango-French advance on Beijing and the end of the war in October 1860.
