Hōjō Sanemasa was now appointed to command at Dazaifu, and instructions were issued for the vigilant guarding of all the coast line in the south. Further, the imperial guards were temporarily withdrawn from Kyōto, and drafted into a large army recruited from the east of the empire and stationed at Dazaifu as well as at other important positions along the coast. Sanemasa was given the command of this army, and other members of the Hōjō family were dispatched to direct the military preparations in Harima and Nagato. Further, the territorial nobles of Kiushū received orders to construct fortifications along the coast, and this work, being vigorously carried on, was completed in 1279. That year the Chinese emperor again sent envoys, seeking to establish friendship and intercourse. They landed at Hakata, but were put to death by order of the shōgun's government. The Regent Tokimune, foreseeing the consequences of these complications, dispatched large bodies of troops from Kamakura to Kiushū, to repel the renewed attack inevitably pending from the west. By this time the feudal society of Japan seems to have been roused to its height of patriotism. It not only was determined to resist the invasion of the world-conqueror, but even plans were made to invade the continent and fight with the Khan on his own ground. The latter, on his part, had now completed his conquest of China, and, having attained the zenith of his power, resolved to gratify his long-cherished desire, supplemented as it was by indignation at the repeated slaughter of his ambassadors in Japan. Accordingly in the middle of 1281, he assembled a force of 100,000 soldiers, whom, together with a contingent of 10,000 Koreans, he sent against Japan under the command of Hwan Bunko. The invading army touched at the island of Iki, and after a cruel massacre of its inhabitants, resumed their voyage toward Dazaifu. Thither the Japanese troops flocked from Kiushū, Chūgoku, and Shikoku to defend their country. Aided by the fortresses that had been erected along the coast, they fought stoutly. The Chinese, however, enjoyed the great advantage of possessing heavy ordnance, with which they bombarded the forts and slaughtered such multitudes of the Japanese soldiers that the latter were unable to meet them in open contest. Organized tactics as much characterized the invaders as personal valor and individual combat did the defending warriors. Nevertheless, the latter continued to resist so obstinately, that, although the contest waged for sixty days, the enemy could not effect a landing. Meanwhile, a rumor reached Kyōto that the Yuan invaders, having borne down all resistance in Kiushū, had pushed on to Nagato, and were on the point of advancing against Kyōto itself, thence to carry their arms into the Tōkai and Hokuriku districts.
