⚔️ Battle of Nagashino (1575)
Rekiden Scenario Template (Kansuke Special)
📘 Scenario Background
In 1575, Takeda Katsuyori laid siege to Nagashino Castle.
Oda Nobunaga and Tokugawa Ieyasu, leading a coalition army of about 38,000 men, advanced to Shitaragahara to confront him.
Nobunaga deployed 3,000 arquebusiers in a three-line volley fire formation behind wooden palisades, effectively stopping the famous Takeda cavalry charge.
The Takeda army suffered a devastating defeat, losing many veteran commanders including Yamagata Masakage and Baba Nobuharu.
Historically, this marked the decline of the Takeda clan.
⚡ But what if the famed strategist Yamamoto Kansuke had survived until this battle?
Could his cunning turn the tide against Oda’s guns? This scenario explores that alternate history.

🔍 Enemy Analysis (by Kansuke)
- Oda relies on arquebusiers protected by palisades: powerful firepower, but dependent on visibility and weather.
- Their triple volley system ensures continuous fire, but consumes ammunition rapidly.
- Weaknesses: poor mobility, vulnerable to flanking attacks, reduced firepower in heavy rain or smoke.
🛡 Kansuke’s Five Stratagems
- Night Raid with Smoke: Use fire and smoke to blind arquebusiers and create chaos at night.
- Bullet Wasting Tactics: Send small units to provoke gunfire and drain enemy ammunition.
- Flank Attack: Maneuver cavalry through forests or riversides to hit their flanks.
- Rain Assault: Time an attack during rain, when matchlocks misfire.
- Supply Line Disruption: Send detachments to cut the enemy’s supply route from Okazaki.
🎯 Initial Choices
- Order a massive cavalry charge against Shitaragahara (Direct Assault)
- Maintain the siege and wait for an opportunity (Attrition Strategy)
- Follow Kansuke’s plan and launch an unconventional strike to neutralize the arquebusiers (Kansuke Special)
