After the fall of Chinju, all the Japanese troops, with the exception of Konishi's corps, were withdrawn from Korea, and the Japanese confined their operations to holding a cordon of twelve fortified camps along the southern coast of the peninsula. These camps were nothing more than bluffs overlooking the sea on the south, and protected on the land side by moats and earthworks.
Konishi's corps covered that interval in nineteen days, storming two forts, carrying two positions, and fighting one pitched battle on the way. Kato's corps, travelling by a circuitous and more arduous road but not meeting with so much resistance, traversed the distance between Fusan and the capital in four days less.
On the 25th, Konishi's troops carried the castle of Fusan by storm, after a brave resistance by the garrison, and, on the 27th, the same fate befell another and stronger fortress lying three miles inland and garrisoned by twenty thousand picked soldiers. Thenceforth, however, it was really a race between the two armies as to which should form the van.
