and turned back to starboard to encircle the Chinese. Concentrating their fire on the cruisers on the Chinese right flank, they quickly destroyed the Chinese cruisers and . The battle quickly devolved into a melee at close range, and the Chinese cruisers and were sunk. In return, the Chinese warships inflicted serious damage on the old ironclad , which had been unable to keep pace with the rest of Itō's fleet, and was eventually forced to disengage and flee. Zhenyuan and Dingyuan hit the auxiliary cruiser Saikyō Maru with four 12-inch shells and inflicted significant damage. The Japanese ships then concentrated their fire on Dingyuan and Zhenyuan.

They quickly captured the fortifications on the eastern side of the city despite heavy fire from Dingyuan and other vessels of the fleet. The capture of the fortresses forced the Chinese ships to withdraw to the western portion of the harbor, where they would be out of range for the guns there. Dingyuan disabled one of the disappearing guns
