Military strategy, Men-at-Arms, and siege tactics.
Men-at-Arms Composition
Counter enemy MaA types for massive damage bonuses. Heavy Infantry beats Light Infantry, Archers beat Light Cavalry, Pikemen beat Heavy Cavalry. Check enemy composition before war.
Knight Effectiveness
Knights deal enormous damage based on their Prowess stat. Invest in martial education for family members. A single 30+ Prowess knight can turn battles.
Siege Warfare
Sieges are won by time or assault. Bring siege engines (Onagers, Trebuchets) to speed up sieges. Assaulting is faster but costs troops. Never assault castles without siege advantage.
Terrain Advantage
Mountains, forests, and river crossings give defenders massive advantages. Lure enemies into favorable terrain or avoid fighting in their defensive positions.
Supply Limits
Large armies starve in low-supply counties. Split armies in friendly territory and merge before battles. Watch the supply indicator to avoid attrition losses.
War Score
Win battles and occupy enemy holdings for war score. 100% war score enforces demands. Capturing the enemy ruler instantly gives maximum war score.
Commander Selection
Assign commanders with high Martial skill and relevant traits. Traits like Aggressive Attacker or Cautious Leader provide combat bonuses matching their style.
Mercenaries and Holy Orders
Hire mercenaries for gold when outnumbered. Holy Orders are free but require piety and a valid holy war. Both can turn the tide of critical wars.
