Which 1575 battle is famous for Oda Nobunaga’s coordinated use of matchlock firearms?

The Battle of Nagashino in 1575 is famous for Oda Nobunaga’s coordinated use of matchlock firearms.

The battle was fought at Nagashino Castle in Mikawa Province. Nobunaga and Tokugawa Ieyasu joined forces against Takeda Katsuyori, whose army attempted to relieve the besieged castle. The allied army used prepared defensive positions, including wooden palisades, while deploying large numbers of arquebusiers.

Popular accounts sometimes claim that soldiers fired in three continuous ranks, creating an entirely new battlefield system. Historians debate how literally that specific sequence should be understood, but the battle clearly demonstrated the growing importance of firearms, fortifications, and disciplined infantry.

The defeat weakened the Takeda clan’s military power. It did not make firearms instantly replace bows or spears; Japanese armies continued using all three weapons for decades.
