  • The Third Unifier – Tokugawa Ieyasu. Part Three.

    The Third Unifier – Tokugawa Ieyasu. Part Three.

    After the disastrous Battle of Mikatagahara in January 1573, contemporaries might have been forgiven for thinking that Tokugawa Ieyasu was finished. His army had been defeated and scattered, several important fortresses had fallen, and Takeda forces were camped deep inside his home province of Mikawa.

    The Battle of Mikatagahara was a disaster from which Ieyasu might not have recovered.

    Fate, however, was on Ieyasu’s side. Though Mikatagahara had been a catastrophe, the Takeda would prove unable to take advantage of their victory. Not long after the Battle, Takeda Shingen, arguably the most formidable warrior of his day, fell ill (some sources say he was wounded in battle, though later stories of Ninja assassinations are likely mythological).

    With their leader bedridden, the Takeda campaign stalled. They tried to keep the full extent of his illness secret, but when Shingen died in May, the once-mighty Takeda army began a full retreat from Mikawa. The Art of War writes that a general should know his enemy, and Ieyasu, student of war that he was, seems to have realised that something was amiss.

    An image depicting Shingen’s illness. He was arguably the most formidable warlord of his day, and his death was a huge strategic boon to the Tokugawa.

    Under Shingen, the Takeda were aggressive and highly capable, but after his (still secret) death, Ieyasu identified several weaknesses and launched a counter-attack, the success of which effectively confirmed his theory that Shingen was gone. With the momentum swinging back towards the Tokugawa, several clans that had defected to the Takeda switched sides again, and Ieyasu was able to swiftly regain the strength lost at Mikatagahara.

    Shingen’s successor, Katsuyori, has been remembered as a poor imitation of his father, though much of what was recorded about him was written by his enemies. In the short term, however, Katsuyori and Ieyasu were fairly evenly matched, and throughout 1574 and into 1575, they traded blows, with the momentum shifting back and forth.

    Takeda Katsuyori. Though perhaps unfairly maligned in later writings, he would prove unable to live up to his father’s legacy.

    Ieyasu had something that Katsuyori didn’t, however, a powerful ally. The death of Shingen had removed a serious (possibly existential) threat to the ambitions of Oda Nobunaga, and in 1575, he was finally able to dispatch significant forces to support Ieyasu’s ongoing campaign against the Takeda.

    In early 1575, Takeda forces once again advanced against Mikawa province, laying siege to the strategically important Nagashino Castle. Sources suggest that the Takeda invested the castle with 15,000 men, whilst the defenders numbered only 500. Despite the disparity in strength, the fortress was situated in terrain that made it difficult for the Takeda to bring their full forces to bear, and for a time, the garrison held out.

    The situation changed dramatically, however, when the garrison’s food supplies were burned. In response, a messenger, Torii Suneemon, slipped through Takeda’s lines and made it to a combined Oda-Tokugawa army that was supposed to have numbered some 38,000 men (30,000 Oda and 8,000 Tokugawa, which goes some way to demonstrating the power dynamic in this ‘alliance’.)

    Suneemon then tried to return to Nagashino to inform the garrison that help was on the way, but he was instead captured by the Takeda. Katsuyori offered him a deal: if he told the garrison that no help was coming, he’d be set free. Instead, Sunemon shouted that relief was on the way, and the garrison should hold out, for which he was crucified in full view of the walls.

    A later (and somewhat dramatised) depiction of Suneemon exhorting the garrison of Nagashino to keep resisting.

    When the Oda-Tokugawa forces arrived two days later, the garrison was still holding out, and the Takeda turned to give battle. Although the Battle of Nagashino is one of the most famous and decisive battles of the Sengoku Jidai, scholars disagree on what actually happened. Nagashino has long been famous for Nobunaga’s innovative use of massed firearms, with thousands of foot soldiers firing in a three-rank system that kept up a constant hail of fire that decimated the Takeda’s famous cavalry charge.

    The exact number of firearms and the tactics used are still debated, but what is known for sure is that Nagashino represented a blow to the Takeda Clan from which they would never recover. In the aftermath, both Ieyasu and Nobunaga moved to take advantage, extending their control over Suruga and Totomi Provinces, and boxing the Takeda up in their traditional home in Kai and Shinano Province (modern Yamanashi and Nagano prefectures)

    An 18th-century depiction of the Battle of Nagashino, with the Oda-Tokugawa forces on the left, and Nagashino Castle on the far right.

    Though Ieyasu had been on the winning side, the victory over the Takeda would mark the time when his relationship with Nobunaga ceased to be an alliance of equals. There was no disputing Nobunaga’s power by this point, and the resources at his disposal dwarfed anything Ieyasu could deploy. Consequently, in the aftermath of Nagashino, Ieyasu found himself a vassal to the Great Lord.

    Perhaps the best evidence of how far the relationship had shifted came in 1579, when, on Nobunaga’s order, Ieyasu had his wife and eldest son put to death on suspicion of conspiring with the Takeda to arrange Nobunaga’s assassination.

    Ieyasu’s first wife, Lady Tsukiyama.

    The long-held theory was that Lady Tsukiyama, Ieyasu’s wife, and his eldest son, Nobuyasu, were indeed conspiring with the Takeda. Some sources portray Lady Tsukiyama as a scheming, evil woman who seduced men into joining her plot, whilst Nobuyasu is said to have been a cruel, vindictive psychopath who committed acts such as shooting random peasants dead during festivals for no reason other than that they danced poorly.

    The catalyst for their death was apparently Nobunaga’s daughter, Tokuhime, who just so happened to be married to Nobuyasu. It is said that she hated her mother-in-law so much that she concocted the entire plot to have both of them removed.

    Ieyasu’s eldest son, Nobuyasu, who was either a traitor, a violent lunatic, the victim of a vindictive wife, or a combination of all three, depending on who you believe.

    There is another school of thought that suggests Nobunaga had nothing to do with the incident and that Ieyasu and Nobuyasu were instead engaged in a long-term feud. Nobuyasu, apparently supported by his mother, is said to have defied his father’s orders and even been plotting open rebellion, with or without the support of the Takeda.

    Faced with such a direct threat to his authority, Ieyasu sought the advice of his overlord, Nobunaga (who also happened to be Nobuyasu’s father in law), who is said to have instructed that, as the matter was an internal family affair, that Ieyasu should do as he thought best, resulting in the execution of Lady Tsukiyama, and Nobuyasu’s seppuku.

    Whether Nobunaga gave the order or Ieyasu acted on his own initiative, this incident highlights the situation Ieyasu faced in the late 1570s. Subordinate to Nobunaga’s power, and insecure at home, despite his successes, there was still no reason to believe that Ieyasu was going to be anything other than a footnote in another man’s story.

    Ooooh, foreshadowing!

  • The Third Unifier – Tokugawa Ieyasu. Part Two.

    The Third Unifier – Tokugawa Ieyasu. Part Two.

    The Battle of Okehazama in 1560 saw Tokugawa Ieyasu’s masters, the Imagawa, dealt a serious blow at the hands of Oda Nobunaga. In the aftermath, Ieyasu began asserting his independence, and in 1562, the so-called “Kiyosu Alliance” between Ieyasu and Nobunaga was formalised.

    The Imagawa, however, were down, but not out, and Ieyasu’s position was far from secure, despite his new alliance. In 1563, the “Mikawa Ikko-Ikki” Rebellion broke out, and in early 1564, when the Imagawa announced their intention to crush Ieyasu, several of his vassals in Mikawa switched sides, joining the Ikko-Ikki or else rising against Ieyasu in anticipation of an Imagawa attack.

    The name “Ikko-Ikki” suggests that the uprising was similar to other religiously motivated risings that occurred throughout Japan during this period. Indeed, the focal point seems to have been several temples in Mikawa; however, some scholars now suggest that the uprising was motivated more by economic reasons, and some even go so far as to say that Ieyasu may have provoked the rising, or at least took advantage of it to cement his control of Mikawa Province.

    A later depiction of the Battle of Azukizaka. Ieyasu is the figure on the white horse on the right.

    While it’s impossible to know for sure, Ieyasu did much to boost his own reputation in putting down the rebellion. At the Battle of Azukizaka (sometimes called the Battle of Batogahara) in January 1564, Ieyasu led his forces in crushing the rebels, despite ferocious fighting. The story goes that Ieyasu charged the enemy fearlessly, and came under heavy gunfire, with several rounds penetrating his armour, but leaving him uninjured, inspiring his men, and leading some rebels to switch sides.

    In the aftermath, Ieyasu banned the Jodo Shinshu sect of Buddhism in Mikawa, only to lift the ban in 1567, just a few years later, lending credence to the argument that the fighting had never been about religious issues but about political control of the province.

    The Honshuji Temple, one of the focal points of the rebellion, as it appears today.

    Before 1566, Ieyasu’s family name was Matsudaira, but around this time, he petitioned the Emperor to change it to Tokugawa. The exact reasons for this are related to the complex (and often impenetrable) genealogies of the Minamoto and Fujiwara Clans, from whom Ieyasu claimed descent. You may remember that Minamoto and Fujiwara were the names of two of Japan’s most ancient and illustrious families, and it was a big deal to claim descent from them.

    This would become much more important later, as only a member of the Minamoto could become Shogun (technically), but that was still decades in the future. At the time, the name change was probably more closely associated with prestige and a desire to assert independence from the Imagawa, with a new name symbolising a new era for the clan.

    Takeda Shingen.

    In 1567, Ieyasu further strengthened his alliance with Nobunaga by marrying his eldest son to Nobunaga’s daughter. However, they were both just nine years old at the time, so the marriage was a political rather than conjugal union. The next year, Ieyasu dispatched forces to support Nobunaga’s march on Kyoto, and in December, he made an alliance with Takeda Shingen and launched a joint invasion of Imagawa territory.

    The attack was a success, but the relationship between Ieyasu and Shingen fell apart almost immediately. According to Tokugawa accounts, it had been agreed that Ieyasu would take Totomi Province, and Shingen would take Suruga. However, it wasn’t long before Takeda forces were also crossing into Totomi, in direct violation of the agreement (which may never have existed to begin with).

    Ieyasu then sought the support of the Hojo Clan, and their Lord, Ujiyasu, who had his own ambitions for the former Imagawa territory. Together, they successfully pushed the Takeda forces back, and in 1570, Ieyasu moved his base from Okazaki Castle in Mikawa Province to Hikuma, which he promptly renamed Hamamatsu, in Totomi. Later that year, he would further prove his value as an ally of Oda Nobunaga by supporting his campaign against the Azai-Asakura Alliance, fighting in the rearguard in the defeat at Kanegasaki, and then providing important reinforcements at the victorious Battle of Anegawa in July.

    In 1571, the alliance would be sorely tested, as the last Ashikaga Shogun, Yoshiaki, sought to rally forces in opposition to Oda Nobunaga, with the ultimate goal of restoring his family’s position. The Anti-Nobunaga coalition (which was, importantly, not necessarily pro-Ashikaga) included the forces of the Azai-Asakura Alliance, the powerful temple of Ishiyama Honganji, and Takeda Shingen, among others.

    Ashikaga Yoshiaki

    In the aftermath of the defeat of the Imagawa, Hojo Ujiyasu, who had favoured an alliance with Ieyasu against the Takeda, died and was replaced by his son, Ujimasa, who reversed his clan’s diplomatic position and reestablished the alliance with Shingen. At this point, Yoshikai, seeking to take advantage of the pressure he was now under, sought to gain Ieyasu’s support, offering him the position of Kanrei or deputy Shogun in exchange.

    Ieyasu refused this offer and chose to retain his alliance with Nobunaga; in response, Takeda Shingen launched an invasion of the Mikawa and Totomi Provinces in September 1572. Leading 20,000 troops, Shingen crossed the Aokuzure Pass, and with the help of several defections amongst Ieyasu’s retainers, swiftly gained control of northern Totomi.

    A later depiction of the Takeda Army advancing into Totomi Province.

    Meanwhile, a separate force invaded Nobunaga’s territory in Mino, meaning that when Ieyasu called for aid, none was readily available. Ieyasu was forced into an impossible situation; his forces were heavily outnumbered by the advancing Takeda, and a pitched battle would almost certainly end in defeat. On the other hand, if he retreated or even stayed on the defensive, he faced the prospect of losing support from his retainers, some of whom had already proved they were willing to switch sides.

    The Takeda headed towards the strategically important Futamata Castle, and Ieyasu had no choice but to try to head them off. The advance guards of both armies clashed at the Battle of Hitokotozaka, and the Tokugawa were soundly beaten, causing them to retreat to the relative safety of Hamamatsu, and giving the Takeda a clear path to lay siege to Futamata, which fell shortly afterwards.

    In the aftermath of this disaster, still more Tokugawa retainers switched sides and joined the Takeda, and it was assumed that Shingen, whose army, strengthened by defections and reinforcements, now stood at around 30,000 men, would march on Hamamatsu. Instead, the Takeda forces bypassed it entirely. It has been suggested that this was a ploy to lure Ieyasu out of the powerful fortress, giving Shingen the opportunity to destroy him in the open.

    If that was the plan, it worked, and despite urging from his retainers to remain in Hamamatsu, Ieyasu was emboldened by some long-awaited reinforcements from Nobunaga and decided to march out and intercept the Takeda. The result was the disastrous Battle of Mikatagahara, in which the Tokugawa were decisively defeated, with Ieyasu himself only being saved by the bravery of his retainers, who fought a rearguard action so ferocious that Ieyasu was allowed to escape, and the Takeda were convinced to call off the pursuit.

    A later depiction of the Battle of Mikatagahara

    The winter of 1572 saw the Takeda forces camping deep inside Tokugawa territory, whilst Ieyasu himself was holed up in Hamamatsu, his army scattered, and his prospects looking very bleak.

    A painting of Ieyasu supposedly made after the defeat at Mikatagahara. Traditional history suggests that Ieyasu commissioned the painting as a reminder of the defeat and a warning against future arrogance; however, this account doesn’t appear in any sources before the 20th century and is now generally believed to be apocryphal.

  • The First Unifier – Oda Nobunaga. Part Two.

    The First Unifier – Oda Nobunaga. Part Two.

    In June 1565, the powerful Miyoshi Clan launched a coup against the Shogun, Ashikaga Yoshiteru. In the Eiroku Incident (named for the era), the Miyoshi successfully killed Yoshiteru, and his brother, Yoshiaki, a rival claimant to the throne, fled the capital, seeking support from regional warlords.

    Miyoshi Yoshitsugu, one of the main leaders in the Eiroku Incident.

    Nobunaga was initially enthusiastic about supporting Yoshiaki and the Shogunate more generally. Sources aren’t clear about Nobunaga’s ambitions at this point, with some arguing he genuinely wanted to restore the Ashikaga, whilst others portray it as cynical politicking, with Nobunaga intending to replace the Miyoshi’s puppet Shogun with his own.

    Regardless, in the short term, military defeat limited Nobunaga’s practical aid, and it wasn’t until September 1568 that he formally recognised Yoshiaki as Shogun and dispatched an army to Kyoto to secure his accession to the throne. There was some resistance, but Nobunaga’s forces would prove triumphant, and Ashikaga Yoshiaki was installed as the 15th (and final) Ashikaga Shogun. It seems that Yoshiaki wanted to install Nobunaga as kanrei, or deputy, but he refused. Moreover, at this point, the Kyoto political community seemed to have viewed Nobunaga as little more than Yoshiaki’s general, rather than a political force in his own right.

    Ashikaga Yoshiaki

    In early 1569, Nobunaga once again proved his worth to the Shogunate by putting down an attempt by the Miyoshi Clan to restore their position in the capital. Shortly after that, Nobunaga issued the denchuonokite, or “Rules of the Palace”, which were a set of nine (with seven more added later) rules for the management of the Shogun’s court. For a long time, it was believed that these rules were the first clear example of Nobunaga imposing his will on the Shogunate, though later research suggests that Yoshiaki agreed to the rules, and it was only later that the relationship between the two men began to break down.

    Nobunaga seems to have intended to return to his own territories after the restoration, serving as a sort of enforcer for the Shogun. However, by this point, the Shogunate was at such a low ebb that he found himself obliged to become closely involved in the running of the government. It has been suggested that the issuing of the “Palace Rules” was part of wider efforts by Nobunaga to reinforce the Shogunate, whilst also reining in the tendency of the Shogun to use his remaining power arbitrarily, favouring his own supporters at the expense of powerful clans elsewhere, who, Nobunaga (rightly) worried, would then become enemies of the Shogun, and be extension, himself.

    Part of the original Palace Rules.

    It was not as though Nobunaga had any trouble finding enemies of his own. In the late 1560s, his forces invaded Ise Province, and in 1570, he led an army north to Wakasa Province to subjugate the Asakura Clan, who had defied him. The invasion went well, but when word reached Nobunaga that the Azai Clan, led by his brother-in-law, had betrayed him, he was forced to retreat.

    The reasons for this sudden betrayal have been much romanticised, with Azai Nagamasa sometimes portrayed as a principled opponent of Nobunaga’s tyranny, or else bound by a close alliance to the Asakura that trumped his loyalty to the Oda. Historians are still divided on the exact cause, but the betrayal was likely a combination of opportunism and genuine fear about Nobunaga’s intentions.

    Nobunaga’s army was defeated at the Battle of Kanegasaki, with Nobunaga himself forced to flee the field. It is said that he was only able to escape because of the rearguard action led by Kinoshita Tōkichirō, who would later be known as Toyotomi Hideyoshi, and who was rewarded with gold by Nobunaga upon his return to Kyoto.

    A later depiction of Hideyoshi in Nobunaga’s service. He first appears in records from the early 1560s, and by the time of Kanegasaki, he had earned a reputation as one of Nobunaga’s most capable subordinates.

    Sources disagree on exactly how severe the defeat was; some state that Nobunaga returned to Kyoto with just ten men, whilst others put his army’s losses at fewer than 1300, out of a total of 30,000. Both numbers may be true, and it would certainly explain why Nobunaga himself seems to have remained calm in the wake of the defeat, inspecting the Imperial Palace the day after he returned to Kyoto.

    Whilst Nobunaga had certainly been forced to retreat, the case for his army remaining largely intact is made by the fact that just a few months after Kanegasaki, he, along with his ally, Tokugawa Ieyasu, led a force of up to 40,000 men in a campaign against the Azai-Asakura, culminating in the Battle of Anegawa, which Nobunaga won, though he was unable to finish either the Azai or Asakura off, despite inflicting heavy casualties on both.

    Nobunaga was prevented from pressing his advantage by events elsewhere. In August, the Miyoshi raised an army in Settsu Province (modern Osaka). Around the same time, the Ishiyama Hongan-ji Temple (on the site of modern Osaka Castle), fearing Nobunaga’s expansionist ambitions, raised an army of its own.

    All this was combined with the ongoing conflict with the Azai-Asakura alliance, and in September, supporters of Ishiyama Hongan-ji launched a rebellion in Ise Province in which Nobunaga’s younger brother, Nobuoki, was killed (or forced to commit seppuku) Faced with all this, Nobunaga chose to leverage his power at court, and in December, an Imperial decree was issued, ordering all sides to stop fighting, which they duly did, saving Nobunaga in the short-term.

    Peace in the Age of the Country at War was only ever a fleeting thing, however. In February 1571, Nobunaga led an army of some 50,000 against the forces of Ishiyama Hongan-ji, resulting in one of his most controversial acts, the burning of Mt Hiei.

    A semi-contemporary image of the burning of Mt Hiei, showing Nobunaga’s forces cutting people down as they try to flee the flames.

    Mt Hiei is one of the most sacred sites in Japanese Buddhism, and in the late 16th Century, its monks were major political players in their own right, with influence at both the Imperial and Shogunate court, and an army of warrior monks to defend their interests. Nobunaga’s attack should be seen in this context, but it was also an incredibly shocking act, which outraged a Japanese political class that took its religion very seriously. One particularly outraged player was Takeda Shingen, who denounced Nobunaga and began a campaign against his ally, the Tokugawa.

    Whilst historians suggest that Shingen’s outrage over Mt Hiei was just a pretext, the invasion of the Tokugawa home province of Mikawa was a serious threat to Nobunaga’s position. Shingen was arguably the most formidable warlord of his time, and may well have proved more than a match for Nobunaga. He was certainly too much for Tokugawa Ieyasu, who was obliged to retreat and call on Nobunaga for help.

    Nobunaga dispatched a force of 3000 men to help, but they, along with the Tokugawa, were decisively defeated at the Battle of Mikatagahara in January 1573. Ieyasu himself barely managed to escape the disaster. In the aftermath, Nobunaga appeared vulnerable, so vulnerable that Ashikaga Yoshiaki, who had begun to chafe under Nobunaga’s regime, raised an army in opposition to him, presumably in the hope that Takeda Shingen was on his way.

    A 19th-century depiction of the Battle of Mikatagahara. If Takeda Shingen had lived long enough to take advantage of the victory, the outcome of the Sengoku Jidai might have been very different.

    Unfortunately for Yoshiaki, Shingen was dead. Though the circumstances of his death are still murky, it ended a serious threat to Nobunaga, perhaps the most serious threat, and he was able to focus his forces on Kyoto, where he swiftly forced Yoshiaki to make peace and resume his position firmly under Nobunaga’s thumb.

    Yoshiaski refused to learn his lesson, however, and a second rebellion broke out not long after, with Shogunate loyalists barricading themselves inside Makishima Castle, which Nobunaga swiftly took, sending Yoshiaki into exile, and effectively bringing an end to the Ashikaga Shogunate, once and for all. Historians debate whether the Shogunate actually ended at this time, as Yoshiaki continued to use the title, and would spend the next few years roaming Japan seeking support to overthrow Nobunaga.

    What is true, though, is that the Ashikaga, long in decline, would never rule from Kyoto again. There had been strongmen before, of course, but they had always ruled through puppet Shoguns, and the institution had remained largely intact. Nobunaga did away with that; though he would never take the title of Shogun for himself, from 1573 until his death, Nobunaga sat at the top of a very precarious pile.

    Nobunaga’s territory is in red, in the centre, surrounded by enemies, or opportunities, depending on your perspective.
