It is true that Konishi Yukinaga, who commanded the first division, would have continued his northward march from Phyong-yang without delay. He argued that China was wholly unprepared, and that the best hope of ultimate victory lay in not giving her time to collect her forces. But the commander-in-chief, Ukida Hideiye, refused to endorse this plan. He took the view that since the Korean provinces were still offering desperate resistance, supplies could not be drawn from them, neither could the troops engaged in subjugating them be freed for service at the front. Therefore it was essential to await the consummation of the second phase of Hideyoshi's plan, namely, the despatch of reinforcements and munitions by water to Phyong-yang. The reader has seen how that second phase fared. The Japanese commander at Phyong-yang never received any accession of strength. His force suffered constant diminution from casualties, and the question of commissariat became daily more difficult. It is further plain to any reader of history--and Japanese historians themselves admit the fact--that no wise effort was made to conciliate the Korean people. They were treated so harshly that even the humble peasant took up arms, and thus the peninsula, instead of serving as a basis of supplies, had to be garrisoned perpetually by a strong army. Chinese Intervention. The Koreans, having suffered for their loyalty to China, naturally looked to her for succour. Again and again appeals were made to Peking, and at length a force of 5000 men, which had been mobilized in the Liaotung peninsula, crossed the Yalu and moved south to Phyong-yang, where the Japanese van had been lying idle for over two months. This was early in October 1592. Memorable as the first encounter between Japanese and Chinese, the incident also illustrated China's supreme confidence in her own ineffable superiority. The whole of the Korean forces had been driven northward throughout the entire length of the peninsula by the Japanese armies, yet Peking considered that 5000 Chinese "braves" would suffice to roll back this tide of invasion. Three thousand of the Chinese were killed and the remainder fled pell-mell across the Yalu. China now began to be seriously alarmed. She collected an army variously estimated at from 51,000 to 200,000 men, and marching it across Manchuria in the dead of winter, hurled it against Phyong-yang during the first week of February 1593. The Japanese garrison did not exceed 20,000, nearly one-half of its original number having been detached to hold a line of forts which guarded the communications with Seoul. Moreover, the Chinese, though their swords were much inferior to the Japanese weapon, possessed great superiority in artillery and cavalry, as well as in the fact that their troopers wore iron mail which defied the keenest blade. Thus, after a severe fight, the Japanese had to evacuate Phyong-yang and fall back upon Seoul. But this one victory alone stands to China's credit.
