In 1860, when British and French troops occupied Dagu Fort in Beitang Fort, the gateway to Tianjin, it was photographed by Italian Ferry Cheveat, who accompanied the British troops who occupied it to Beijing as a military photographer.

On August 1, 1860, the wooden ammunition depot in Beitang Fort, built in 1550, was looted. In 1840, the Qing court had expanded the northeast fort into five: Dongying, South Ying, North Ying, Hua Ying, and the only new fort, Dongying became the base.
From August 21 to 22, 1860, a large number of Qing soldiers were killed in a bloody battle at Dagukou in Beitang Fort. After Dagu Fort was occupied by British and French troops, the bodies of the dead Qing soldiers were scattered all over the place. The Dagu Fort occupied by the British and French forces was an important fortress to defend against attacks on the city.

Qing soldiers fell prey to the cannons of the allied forces.
