Qing dynasty

Chinese forts were unable to withstand attacks by European weaponry, as they were designed without angled glacis and many did not have protected magazines. The limited range of the Qing cannon allowed the British to bombard the Qing defences from a safe distance, then land soldiers to storm them with minimal risk. Many of the larger Chinese guns were built as fixed emplacements and were unable to be maneuvered to fire at British ships. The failure of the Qing fortifications coupled with the Chinese underestimation of the Royal Navy allowed the British to force their way up major rivers and impede Qing logistics. Most notably, the powerful series of forts at Humen were well positioned to stop an invader from proceeding upriver to Guangzhou, but it had not been considered that an enemy would attack and destroy the forts themselves, as the British did during the war.
