On the way from Okazaki, which was the stronghold of Hirotada, the party fell into the hands of Nobuhide's officers, and Ieyasu was confined in a temple where he remained until 1559, when he obtained permission to return to Okazaki, being then a vassal of the Imagawa family. But when (1569) the Imagawa suffered defeat in the battle of Okehazama, at the hands of Oda Nobunaga, Ieyasu allied himself with the latter. In 1570, he removed to Hamamatsu, having subjugated the provinces of Mikawa and Totomi. He was forty years old at the time of Nobunaga's murder, and it has been shown above that he espoused the cause of the Oda family in the campaign of Komak-yama. At forty-nine he became master of the Kwanto and was in his fifty-sixth year when Hideyoshi died. Ieyasu had nine sons: (1) Nobuyasu; (2) Hideyasu (daimyo of Echizen); (3) Hidetada (second shoguri); (4) Tadayoshi (daimyo of Kiyosu); (5) Nobuyoshi (daimyo of Mito); (6) Tadateru (daimyo of Echigo); (7) Yoshinao (daimyo of Owari); (8) Yorinobu (daimyo of Kii), and (9) Yorifusa (daimyo of Mito). He had also three daughters; the first married to Okudaira Masanobu; the second to Ikeda Terumasa, and the third to Asano Nagaakira.
EVENTS IMMEDIATELY PRIOR TO THE BATTLE OF SEKIGAHARA
The political complications that followed the death of the Taiko are extremely difficult to unravel, and the result is not commensurate with the trouble. Several annalists have sought to prove that Ieyasu strenuously endeavoured to observe faithfully the oath of loyalty made by him to Hideyoshi on the latter's death-bed. They claim for him that until his hands were forced he steadfastly and faithfully worked in the interests of Hideyoshi. But his acts do not lend themselves to any such interpretation. The best that can be said of him is that he believed himself to have been entrusted by the Taiko with discretionary power to determine the expediency of Hideyori's succession, and that he exercised that power in the interests of the Tokugawa family, not of the Toyotomi.
Circumstances helped him as they do generally help great men. From the time of the birth of the lady Yodo's second son, the official world in Kyoto had been divided into two factions. The Hidetsugu catastrophe accentuated the lines of division, and the Korean campaign had a similar effect by affording a field for bitter rivalry between the forces of Konishi Yukinaga, who belonged to the Yodo faction, and Kato Kiyomasa, who was a protege of Hideyoshi's wife, Yae. Further fuel was added to this fire of antagonism when the order went forth that the army should leave Korea, for the Kato faction protested against surrendering all the fruits of the campaign without any tangible recompense, and the Konishi party insisted that the Taiko's dying words must be obeyed implicitly. In this dispute, Ishida Katsushige, the chief actor in the Hidetsugu tragedy, took a prominent part. For, when in their capacity as belonging to the Board of Five Administrators, Ishida and Asano Nagamasa were sent to Kyushu to superintend the evacuation of the Korean peninsula, they, too, fell into a controversy on the same subject. Ieyasu stood aloof from both parties. His policy was to let the feud develop and to step in himself at the supreme moment.
On the other hand, it was the aim of Ishida Katsushige to involve the Tokugawa chief, thus compassing his downfall and opening an avenue for the ascension of Ishida himself to the place of dictator. Allied with Ishida in this plot was his colleague on the Board of Five Administrators, Masuda Nagamori. Their method was to create enmity between Ieyasu and Maeda Toshiiye, to whom the Taiko had entrusted the guardianship of Hideyori and of the Osaka Castle. This design was barely thwarted by the intervention of Hosokawa Tadaoki (ancestor of the present Marquis Hosokawa). Ieyasu was well informed as to Ishida's schemes on two other occasions; the first immediately before, the second just after, the death of the Taiko. In each case rumours of an armed outbreak were suddenly circulated in Fushimi for the purpose of creating confusion such as might furnish an opportunity to strike suddenly at Ieyasu. These essays failed in both instances, and the Tokugawa chief, instead of retaliating by direct impeachment of Ishida, applied himself to cementing close relations with certain great daimyo by matrimonial alliances. Such unions had been implicitly interdicted by the Taiko, and the procedure of Ieyasu elicited a written protest from the boards of the Five Senior Ministers and the Five Administrators. They threatened Ieyasu with dismissal from the former board unless he furnished a satisfactory explanation. This he declined to do and for some time a very strained situation existed in Kyoto, an armed struggle being ultimately averted by the good offices of the Three Middle Ministers.
It was evident, however, that the circumstances had become critical, and it was further evident that, as long as Ishida Katsushige's intrigues continued, a catastrophe might at any moment be precipitated. Sensible of these things, a party of loyal men, spoken of in history as the "seven generals"—Ikeda Terumasa (ancestor of the present Marquis Ikeda); Kato Kiyomasa; Kuroda Nagamasa (son of Kuroda Yoshitaka, and ancestor of the present Marquis Kuroda); Fukushima Masanori, Asano Yukinaga (son of Asano Nagamasa and ancestor of the present Marquis Asano); Hosokawa Tadaoki, and Kato Yoshiaki (ancestor of the present Viscount Kato)—vowed to take Ishida's life, while he was still in Osaka Castle, whither he had gone (1599) to attend the death-bed of his friend, Maeda Toshiiye. Ishida, finding himself powerless to resist such a combination after the death of Maeda, took an extraordinary step; he appealed to the protection of Ieyasu—that is to say, to the protection of the very man against whom all his plots had been directed. And Ieyasu protected him.
We are here confronted by a riddle which has never been clearly interpreted. Why did Ishida seek asylum from Ieyasu whom he had persistently intrigued to overthrow, and why did Ieyasu, having full knowledge of these intrigues, grant asylum? Possibly an answer to the former question can be furnished by the fact that Ishida was in sore straits. Attending Maeda Toshiiye's death-bed, he had seen the partisans of the deceased baron transfer their allegiance to Ieyasu through the intervention of Hosokawa Tadaoki, and he had learned that his own life was immediately threatened by the seven generals. Even if he succeeded (which was very problematical) in escaping from Osaka to his own castle of Sawa-yama, in Omi province, the respite could have been but brief and such a step would have been equivalent to abandoning the political arena. Only a very strong arm could save him, and with consummate insight he may have appreciated the Tokugawa chief's unreadiness to precipitate a crucial struggle by consenting to his death.
But what is to be said of Ieyasu? Unwilling to admit that his astuteness could ever have been at fault, some historians allege that the Tokugawa chief saved Ishida's life with the deliberate purpose of letting him discredit himself and his partisans by continued intrigues. These annalists allege, in fact, that Ieyasu, acting on the advice of Honda Masanobu, by whose profound shrewdness he was largely guided, saved the life of Ishida in order that the latter's subsequent intrigues might furnish a pretext for destroying Hideyori. That, however, is scarcely conceivable, for Ishida had many powerful confederates, and the direct outcome of the leniency shown by Ieyasu on that occasion was an armed struggle from which he barely emerged victorious. The truth seems to be that, for all his profound wisdom, Ieyasu erred in this instance. Ishida Kotsushige outwitted him. For, during the very days of his asylum in Fushimi, under the protection of Ieyasu, Ishida opened secret communication with Uesugi Kagekatsu and invited him to strike at the Tokugawa. Uesugi consented. It must be observed that the character of Ishida has been portrayed for posterity mainly by historians who were under Tokugawa influence. Modern and impartial annalists are by no means so condemnatory in their judgment of the man. In whatever arts of deception Ishida excelled, Ieyasu was at least his equal; while in the matter of loyalty to the Toyotomi family, Ishida's conduct compares favourably with that of the Tokugawa leader; and if we look at the men who attached themselves to Ishida's cause and fought by his side, we are obliged to admit that he must have been highly esteemed by his contemporaries, or, at any rate, that they recognized in him the champion of Hideyori, at whose father's hands they had received such benefits.
ORGANIZATION OF THE JAPANESE EMPIRE AT THE CLOSE OF THE SIXTEENTH CENTURY
The realm of Japan was then held by 214 feudatories, each having an annual income of at least 10,000 koku (omitting minor landowners). These 214 estates yielded to their holders a total income of nearly nineteen million koku, and of that aggregate the domains of the five noblemen forming the Board of Senior Statesmen constituted one-third. Tokugawa Ieyasu was the wealthiest. His domains in the eight provinces forming the Kwanto yielded an income of 2,557,000 koku. Next on the list came Mori Terumoto with 2,205,000 koku, and Uesugi Kagekatsu with 1,200,000 koku. The latter two were partisans of Ishida. But direct communication between their forces was difficult, for while the Mori domains covered the nine provinces on the extreme west of the main island, Uesugi's lay on the north of the Kwanto, whence they stretched to the shore of the Japan Sea. Fourth and fifth on the Board of Senior Statesmen were Maeda Toshiiye, whose fief (835,000 koku) occupied Kaga and Etchu; and Ukita Hideiye (574,000 koku), whose castle stood at Oka-yama, in Bizen. All these, except Maeda embraced the anti-Tokugawa cause of Ishida Katsushige, and it thus becomes easy to understand the desire of Ishida to win over Maeda Toshinaga, son of Toshiiye, to his camp. On the side of Ieyasu's foes were also marshalled Shimazu Yoshihisa, feudal chief of Satsuma (700,000 koku); Satake Yoshinobu of Hitachi province (545,700 koku); Konishi Yukinaga in Higo (200,000 koku), who was counted one of the greatest captains of the era, and, nominally, Kohayakawa Hideaki in Chikuzen (522,500 koku). With Ieyasu were the powerful daimyo: Date Masamune of Sendai (580,000 koku); Kato Kiyomasa of Kumamoto (250,000 koku); Hosokawa Tadaoki of Tango (230,000 koku); Ikeda Terumasa of Mikawa (152,000 koku), and Kuroda Nagamasa of Chikuzen (250,000 koku). This analysis omits minor names.
