Yoshisada, when he learned of the presentation of this memorial, seized the Ashikaga manors within his jurisdiction and addressed to the Throne a countermemorial in which he conclusively proved the falsehood of Takauji's assertion with reference to military affairs; charged him with usurping the titles of governor-general of the Kwanto, and shogun; declared that Prince Morinaga, the mainstay of the restoration, had become the victim of Takauji's slanders, and asked for an Imperial mandate to punish Takauji and his brother, Tadayoshi. It is significant that the leal and gallant Yoshisada did not hesitate thus openly to assert the innocence and merits of Prince Morinaga, though only a few months had elapsed since the Emperor himself had credited his most unhappy son's guilt. While Go-Daigo hesitated, news from various provinces disclosed the fact that Takauji had been tampering with the bushi in his own interests. This settled the question. Takauji and Tadayoshi were proclaimed rebels, and to Nitta Yoshisada was entrusted the task of chastising them under the nominal leadership of Prince Takanaga, the Emperor's second son, to whom the title of shogun was granted.
TAKAUJI ENTERS KYOTO
In the beginning of November, 1335, the Imperial force moved eastward. It was divided into two armies. One, under Yoshisada's direct orders, marched by the Tokaido, or eastern littoral road; the other, under Yoshisada's brother, Wakiya Yoshisuke, with Prince Takanaga for titular general, advanced along the Nakasen-do, or inland mountain-road. The littoral army, carrying everything before it, pushed on to the capital of Izu, and had it forced its attack home at once, might have captured Kamakura. But the Nitta chief decided to await the arrival of the Nakasen-do army, and the respite thus afforded enabled the Ashikaga forces to rally. Tadayoshi reached the Hakone Pass and posted his troops on its western slopes in a position of immense natural vantage, while Takauji himself occupied the routes on the north, his van being at Takenoshita.
The Imperialists attacked both positions simultaneously. Takauji not only held his ground, but also, being joined by a large contingent of the Kyoto men who, under the leadership of Enya Takasada, had deserted in the thick of the fight, he shattered his opponents, and when this news reached Hakone on the following morning, a panic seized Yoshisada's troops so that they either fled or surrendered. The Nitta chieftain himself retired rapidly to Kyoto with a mere remnant of his army, and effected a union with the forces of the ever-loyal Kusunoki Masashige and Nawa Nagatoshi, who had given asylum to Go-Daigo at the time of the escape from Oki. The cenobites of Hiei-zan also took the field in the Imperial cause. Meanwhile, Takauji and Tadayoshi, utilizing their victories, pushed rapidly towards Kyoto. The heart of the samurai was with them, and they constantly received large accessions of strength. Fierce fighting now took place on the south and east of the capital. It lasted for several days and, though the advantage was with the Ashikaga, their victory was not decisive.
An unlooked-for event turned the scale. It has been related above that, in the struggle which ended in the restoration of Go-Daigo, Akamatsu Norimura was chiefly instrumental in driving the Hojo from Rokuhara; and it has also been related that, in the subsequent distribution of rewards, his name was omitted for the slight reason that he had, at one period, entered religion. He now moved up from Harima at the head of a strong force and, attacking from the south, effected an entry into Kyoto, just as he had done three years previously. Go-Daigo fled to Hiei, carrying the sacred insignia with him, and on the 24th of February, 1336, the Ashikaga armies marched into the Imperial capital.
TAKAUJI RETIRES TO KYUSHU
At this stage succour arrived for the Imperialists from the extreme north. In the arrangement of the local administration after Go-Daigo re-occupied the throne, the two northern provinces of Mutsu and Dewa had been separated from the Kwanto and placed under the control of Prince Yoshinaga, with Kitabatake Akiiye for lieutenant. The latter, a son of the renowned Chikafusa, was in his nineteenth year when the Ashikaga revolted. He quickly organized a powerful army with the intention of joining Yoshisada's attack upon Kamakura, but not being in time to carry out that programme, he changed the direction of his march and hastened towards Kyoto. He arrived there when the Ashikaga troops were laying siege to Hiei-zan, and effecting a union with the Imperialists, he succeeded in raising the siege and recovering the city.
It is unnecessary to follow in detail the vicissitudes that ensued. Stratagems were frequent. At one time we find a number of Yoshisada's men, officers and privates alike, disguising themselves, mingling with the Ashikaga army, and turning their arms against the latter at a critical moment. At another, Kusunoki Masashige spreads a rumour of Yoshisada's death in battle, and having thus induced Takauji to detach large forces in pursuit of the deceased's troops, falls on him, and drives him to Hyogo, where, after a heavy defeat, he has to flee to Bingo. Now, for a second time, the Ashikaga cause seemed hopeless when Akamatsu Norimura again played a most important role. He provided an asylum for Takauji and Tadayoshi; counselled them to go to the west for the purpose of mustering and equipping their numerous partisans; advised them to obtain secretly a mandate from the senior branch of the Imperial family so that they too, as well as their opponents, might be entitled to fly the brocade banner, and having furnished them with means to effect their escape, returned to Harima and occupied the fortress of Shirahata with the object of checking pursuit. At this point there is a break in the unrelenting continuity of the operations. It should obviously have been the aim of the Imperialists to strike a conclusive blow before the Ashikaga leaders had time to assemble and organize their multitudinous supporters in Shikoku, Kyushu, and the provinces on the north of the Inland Sea. This must have been fully apparent to Kusunoki Masashige, an able strategist. Yet a delay of some weeks occurred.
A quasi-historical record, the Taiheiki, ascribes this to Yoshinaga's infatuated reluctance to quit the company of a Court beauty whom the Emperor had bestowed on him. Probably the truth is that the Imperialists were seriously in want of rest and that Yoshisada fell ill with fever. Something must also be attributed to a clever ruse on the part of Akamatsu Norimura. He sent to Yoshisada's headquarters a message promising to give his support to the Imperialists if he was appointed high constable of Harima. Ten days were needed to obtain the commission from Kyoto, and Norimura utilized the interval to place the defenses of Shirahata fortress in a thoroughly secure condition. Thus, when his patent of high constable arrived, he rejected it with disdain, saying that he had already received a patent from the shogun, Takauji, and was in no need of an Imperial grant which "could be altered as easily as turning one's hand."
Yoshisada, enraged at having been duped, laid siege to Shirahata but found it almost invulnerable. It was on March 11, 1336, that Takauji went westward from Bingo; it was on the 2nd of April that Yoshisada invested Shirahata, and it was on the 3rd of July that the siege was raised. The Ashikaga brothers had enjoyed a respite of more than three months, and had utilized it vigorously. They were at the Dazai-fu in Chikuzen in June when a message reached them that Shirahata could not hold out much longer. Immediately they set their forces in motion, advancing by land and water with an army said to have numbered twenty thousand and a fleet of transports and war-junks totalling seven thousand. At the island, Itsukushima, they were met by a Buddhist priest, Kenshun, bearer of a mandate signed by the ex-Emperor Kogon of the senior branch, and thus, in his final advance, the Ashikaga chief was able to fly the brocade banner. In the face of this formidable force the Imperialists fell back to Hyogo—the present Kobe—and it became necessary to determine a line of strategy.
