A while back I made a post asking people here for their opinions on the Battle of Sekigahara, and I found the discussion quite interesting.
So this time I’m looking at one of the most famous victories of Oda Nobunaga, the Battle of Nagashino.
Often remembered as the battle in which firearms decisively defeated the supposedly invincible Takeda cavalry, Nagashino is easily one of the most famous battles in Japanese history, and perhaps one of the better known Japanese battles outside of Japan as well.
Now, I’ve always heard people discuss Nagashino in the context of Nobunaga’s innovative use of firearms, and the disastrous decision of Takeda Katsuyori to attack his fortified positions. But I’ve also come across arguments that the traditional story of thousands of cavalrymen charging headlong into three ranks of arquebusiers is something of an exaggeration, and that the battle was considerably more complicated than is often presented.
And that got me thinking, much like with Sekigahara, what would people with a better understanding of other periods as well as military history in general think of the battle? Particularly the decisions made by both commanders, and whether Nagashino really deserves its reputation as a revolutionary moment in military history.
The battle saw the combined armies of Oda Nobunaga and Tokugawa Ieyasu fight against the Takeda army under Takeda Katsuyori in 1575. Traditional estimates place the Oda-Tokugawa forces at roughly 38,000 men, against around 15,000 Takeda troops.
Katsuyori had invaded Mikawa Province and laid siege to Nagashino Castle, defended by a small Tokugawa garrison of roughly 500 men under Okudaira Sadamasa. With the defenders holding out, Nobunaga and Ieyasu assembled a large relief army and advanced towards the castle. Rather than attempt to confront the Takeda in open ground, the allies established a strong defensive position at Shitaragahara, a short distance west of Nagashino. Nobunaga deployed his troops along a roughly north-south line, with wooded hills protecting one flank and the Toyokawa River towards the other. The position was further strengthened by the Rengogawa stream running across its front, muddy ground, and extensive wooden palisades constructed to obstruct the attacking Takeda troops.
Nobunaga positioned large numbers of arquebusiers behind these defences, supported by spearmen and other infantry. According to the famous traditional account, he deployed approximately 3,000 arquebusiers in three rotating ranks, allowing them to maintain a continuous volume of fire. Although the precise number of firearms and the use of organised rotating volleys remain disputed, the concentration of firearms behind prepared defensive works was nevertheless an important feature of the allied position. Meanwhile, Katsuyori advanced with the bulk of his army to confront the relief force, leaving several thousand men to maintain the siege of Nagashino Castle. His commanders, including veterans who had served under his father Takeda Shingen, reportedly disagreed over whether to risk a pitched battle against the numerically superior enemy.
The fighting began early in the morning, as the Takeda advanced against the Oda-Tokugawa positions. Katsuyori’s forces launched repeated assaults across the Shitaragahara battlefield, attempting to break through the allied defensive line. The attackers had to negotiate the stream, uneven and muddy terrain, and wooden palisades while coming under heavy arquebus fire. The traditional account describes successive waves of Takeda cavalry being annihilated by disciplined volleys, although historians have questioned whether the attacks were predominantly mounted charges, with evidence suggesting that much of the fighting involved dismounted samurai and infantry. Nevertheless, the Takeda repeatedly pressed forward, with fierce fighting developing around the defensive barriers as attackers attempted to close with the Oda and Tokugawa troops.
Despite suffering heavy casualties, the Takeda continued their assaults for several hours. Commanders such as Yamagata Masakage, Naito Masatoyo and Sanada Nobutsuna were killed during the fighting, while the Oda-Tokugawa forces largely maintained their defensive positions. The combination of concentrated missile fire, difficult terrain and prepared obstacles made it extremely difficult for the attackers to exploit any local successes. Rather than defeating the enemy in a single devastating volley, the allied army gradually wore down the Takeda through repeated failed assaults and sustained fighting along the defensive line.
Meanwhile, another important development was taking place behind the Takeda army. Nobunaga and Ieyasu had dispatched a separate force under Sakai Tadatsugu, numbering several thousand men, to move through the surrounding hills and attack the Takeda positions around Nagashino Castle. Moving under cover of darkness, Sakai’s troops launched a surprise attack against the Takeda fortifications at Tobigasuyama, threatening the besieging forces and their communications. The operation succeeded in relieving pressure on the castle and placed the Takeda in an increasingly dangerous position, with their main army engaged against a numerically superior enemy while their rear was being attacked.
As the fighting continued, the Takeda assaults lost momentum and their formations began to disintegrate. With many of his most experienced commanders dead, mounting casualties and the situation around Nagashino deteriorating, Katsuyori eventually ordered a retreat. The withdrawal turned into a disastrous defeat, with the allied forces pursuing the retreating Takeda and inflicting further losses. Baba Nobuharu was among the senior commanders killed during the retreat. By the end of the battle, the Takeda had suffered enormous casualties, traditionally estimated at around 10,000 men, although the precise figure is uncertain. The defeat cost the clan much of its experienced military leadership and severely weakened its ability to challenge Nobunaga and Ieyasu, contributing to its eventual destruction in 1582.
How do you judge the plans of the two sides? Do you think Katsuyori’s decision to attack was as foolish as it is often portrayed, or was there a reasonable tactical justification for attempting to defeat the relief army before the siege collapsed? And how much credit should Nobunaga and Ieyasu receive for their defensive preparations, choice of terrain and the flanking operation against the Takeda rear?
I’m also particularly interested in how people would compare Nagashino to battles from other periods, especially regarding the effectiveness of field fortifications and firearms against an attacking enemy. Do you think there were things either side could’ve done better? Do you think there are things worthy of praise?
