Oda Nobunaga and Firearms

• Portuguese Influence: Nobunaga developed a relationship with the Portuguese, acquiring firearms to enhance his military capabilities.

• Armament of Ashigaru: Transitioned his infantry from traditional spears to firearms to increase their effectiveness in battle.

• Large Force of Matchlocks: At the Battle of Nagashino, Nobunaga and his ally, Tokugawa Ieyasu, assembled approximately 1,000 to 1,500 trained soldiers armed with matchlocks.

The Takeda Threat

• Preceding Battles: The aggressions of the Takeda clan began in 1572, with notable battles against the Tokugawa that escalated tensions.

• Death of Takeda Shingen: Shingen's death in 1573 led to instability and power struggles within the Takeda clan under his son, Katsuyori.

• Katsuyori's Campaigns: Attempted assaults on Tokugawa lands and ultimately the siege of Nagashino Castle.

The Siege of Nagashino Castle

• Nagashino Castle Significance: Positioned strategically between two streams, it was a crucial defensive fortification against Katsuyori's forces.

• Desperate Defense: The castle defenders sent word to Tokugawa for help as they faced imminent capture.

• Formation of Allied Forces: Tokugawa called upon Nobunaga; together they mobilized approximately 30,000 troops to counter the Takeda’s 15,000.

The Setup for Battle

• Tactical Positioning: Oda and Tokugawa utilized high ground to establish their defensive line, employing bamboo palisades and strategic fortifications.

• Environmental Advantage: The battle occurred during the rainy season, with fog hindering Takeda’s visibility—a crucial advantage for the defending Oda forces.

The Battle Tactics

• Innovative Matchlock Strategy: Nobunaga implemented a rotation firing tactic with matchlock units to create a deadly volley fire against the Takeda cavalry.

• Adaptation by Takeda: Realizing their cavalry’s vulnerability, Katsuyori’s forces attempted to engage on foot but struggled against the devastating fire from the defenders.

• Outcome: Oda and Tokugawa successfully repelled the Takeda, leading to significant losses for Katsuyori's commanders and ultimately his retreat.

Aftermath and Significance

• Impact on Takeda Clan: The defeat marked the end of Takeda's threat and solidified Oda Nobunaga's power.

• Persistence of Firearms: Nobunaga's use of firearms influenced future warfare strategies among daimyos, changing the dynamics of the Warring States period (Sengoku Jidai).

• Shift Towards Centralization: This victory allowed Oda Nobunaga to pursue his unification efforts in Japan, culminating in further military actions and political maneuvering by 1582.

Nobunaga’s Ruthlessness: Mount Hiei

• Mount Hiei Context: In 1571, faced with opposition from the Tendai monks of Enryaku-ji temple, Nobunaga ordered a campaign that culminated in the massacre at Mount Hiei.

• Massacre Overview: 30,000 troops surrounded the temple, leading to widespread destruction — 3,000 structures and thousands of deaths.

• Political Implications: This action signified a shift in Nobunaga's character from an unorthodox leader to a more brutal ruler willing to employ devastating tactics.

Nobunaga's Legacy and Hideyoshi's Rise

• Aftermath of Nobunaga's Death: Nobunaga was betrayed in 1582 by Akechi Mitsuhide during a tea ceremony, leading to his ritual suicide.

• Toyotomi Hideyoshi: Rising from a peasant background, Hideyoshi emerged as a key figure in consolidating Nobunaga’s unification efforts after Akechi's defeat.

• Hideyoshi's Rule: Though unable to claim the title of shogun, he effectively controlled Japan by acting as regent and continuing military campaigns.

• Invasion of Korea: Hideyoshi's later invasions were driven by concern for his legacy and potential threats to his rule, despite being a military powerhouse on land.

Conclusion

• Transition of Power: After Hideyoshi’s death in 1598, power struggles ensued, eventually leading to Tokugawa Ieyasu establishing a lasting shogunate, which solidified Japan’s political landscape well into the 19th century.
