The advantage of the navy over the army lies in their speed.
While the army troops were still assembling and resting, the naval warships, after replenishing some coal and fresh water, immediately set sail north.
Even the three Wolf-class warships, being cruisers, had more reserves of fresh water and coal, and thus didn't even need to resupply.
The six ironclad warships advanced along the coastline and by noon the next day had arrived north of Dongwan Island, blocking the off-shore waters of Dongwan Port.
The Shen Country's navy, stationed at Dongwan Port, tried to break out but ultimately failed. They suffered heavy losses, nearly wiping out their entire fleet.
Aside from one Ming Wheel Ship warship that remained in the harbor, all other warships that went out to battle were sunk, leaving Dongwan Island completely isolated.
