The Battle of Nagashino, 1575

The loss of Shingen in 1573 had ostensibly only slowed the Takeda war machine. The following year Takeda Katsuyori, Shingen's heir, pulled off a strategic coup with the capture of Taketenjin Castle in Totomi.  Tokugawa Ieyasu, whose efforts to relieve Taketenjin failed, had his hands full with Katsuyori; while not the ruler his father had been, Katsuyori was brave and was not lacking in aggression. Combined with the skilled Takeda army and the late Shingen's experienced cadre of captains, Katsuyori's indomitable spirit made him a formidable foe

In May 1575 Katsuyori hatched a plot whereby one of Ieyasu's retainers would betray his lord and open the gates of Hamamatsu Castle to the approaching Takeda army. Katsuyori was halfway to Hamamatsu before he learned that the plot had been uncovered and Ieyasu alerted. Perhaps as a consolation prize, Katsuyori turned his attentions to Nagashino Castle, a fort held by a certain Okudaira Sadamasa. When direct attack failed to reduce the garrison, Katsuyori settled in for a siege and attempted to mine the walls. Nagashino may well have fallen had it not been for a brave member of the garrison, Torii Sune'emon, who slipped through the Takeda lines and delivered a message to Ieyasu explaining the castle's predicament. Ieyasu sent Torii back to let Nagashino know that he had no intention of abandoning him, but he was captured and crucified by the Takeda in the attempt.

Tokugawa was determined to rescue Nagashino, but lacked the manpower to do so alone. Nobunaga, on the other hand, was hesitant, perhaps reluctant to take so many of his men and leaders so far from the Kyôto area. In frustration, Ieyasu once again played his trump card - he threatened to join the Takeda and attack Oda as part of their vanguard! Faced with this rather unpleasant prospect, Nobunaga changed his mind and agreed to throw his full weight into the effort. Moving quickly, he gathered an army of some 30,000 men, to be commanded by some of his best commanders, including Shibata Katsuie, Hashiba Hideyoshi, and Takigawa Kazumasu. Tokugawa brought about 8,000 men of his own, tough Mikawa men whose skill would once again more than make up for their relative lack in numbers. Perhaps most importantly, Nobunaga arranged to deal with the vaunted Takeda cavalry by bringing along a sizable contingent of riflemen (around 3,000) and logs to throw up a palisade for protection.

In late June, the Oda and Tokugawa forces converged on Nagashino, putting Katsuyori in a difficult spot. Nagashino Castle, bolstered by Torii's brave sacrifice, was holding firm, leaving the weary Takeda army outnumbered AND without a base from which to conduct operations from. The older - and wiser - Takeda retainers urged Katsuyori to either retreat or make one last push to take the castle. Unfortunately for them and the Takeda clan, Katsuyori chose to do neither - he ordered preparations for an all-out attack on the Oda and Tokugawa army massed just to their west. The attack, in retrospect, was almost bound to fail - even had Nobunaga left most of his guns at home and dispensed with his palisade building. The Takeda were tired from weeks in the field in poor weather, outnumbered almost three to one, and faced with attacking over ground broken by foliage, dips, and a stream. It has been said that Katsuyori planned to attack in the hopes that rain would render Nobunaga's guns useless, but this apologetic excuse seems unlikely. In truth, Nagashino seems to have simply been a tremendous mistake on the part of an impetuous commander. These judgments aside, the battle progressed poorly for the Takeda from the first. On the night of 27 June, the day before the actual battle, Sakai Tadatsugu led a raid into the Takeda camp and killed one of Shingen's surviving brothers, Takeda Nobuzane. When day broke, any possible Takeda hopes for rain were dashed by the rays of a bright morning sun. Nonetheless, Katsuyori gave the order to attack, sending nearly 10,000 of his troops across the Shidarahara against 38,000 troops established on superior ground and entrenched with wooden palisades. Matchlock fire produced the first casualties, and likely served to further disrupt formations already strained by the difficult terrain. In a scene vaguely reminiscent of Gettysburg, the Takeda vanguard managed to reach the enemy lines and even cut into their ranks before being thrown back by counterattacks led by fresh, eager troops. On the northern flank, Baba Nobuharu's Takeda contingent managed to capture some of the high ground, and held their integrity together well. To his immediate south, however, Baba's comrades fared much worse. Yamagata Masakage and Naito Masatoyo, two of the greatest Takeda generals, were killed in the melee, the former by a bullet and the latter by enemy spears. With the Takeda wavering, Nobunaga ordered a general pile-on, sending his ashigaru pouring out from behind the palisades. The battle had devolved into butchery, and Katsuyori added to the fiasco by sending in his reserves, which did little but add to the casualty list and encourage the Nagashino garrison to mount a sally. Finally, after hours of bitter struggle, Katsuyori was convinced to retreat by Baba Nobuharu, who covered his master's flight until he and his men were themselves killed. Katsuyori left as many as 10,000 of his men dead at Nagashino. 28 June 1575 was Nobunaga's greatest achievement, a victory as tactically decisive as Okehazama and ultimately of great strategic significance. The victory at Nagashino all but secured his eastern flank and allowed him to throw his weight into the siege of the Honganji and consolidate his recent gains. Takeda Katsuyori was beaten but not vanquished, and would continue to harass Tokugawa, yet, as a regional power, the Takeda were broken.

Nobunaga returned to Kyoto and prepared for new battles and new enemies.
