Siege battles are the largest combat scenes in Huaxia: Warring States, separate in feel and scale from personal combat. A siege puts a player-led army against a city or stronghold's walls and garrison, with hundreds of units on each side. The developer has stated the strategic combat layer is being optimised toward five hundred versus five hundred troop battles, which sets the upper bound for what a siege scene can hold.
When a Siege Begins
Sieges are usually the climax of a conquest arc. A clan declares war or seizes a contested prefecture, marches an army across the world map, and arrives at the target's gates. Some sieges are also possible against bandit-held strongholds during the early game. The world map shows ongoing sieges, including ones the player is not part of, and a player can choose to intervene as ally or attacker.
Camp setup at the siege site no longer requires consumable items in the current build, lowering the friction of preparing for a long engagement.
Pre-Battle Preparation
The hours before a siege are where the fight is largely decided. Useful preparations include:

Logistics: food, equipment, and replacement levies. A siege without supplies starves the attacker before the wall does.
Retainer assignments. Retainers can be assigned as field generals, each managing a wing or unit type during the battle.
Unit composition. A balanced army across unit types handles the surprises of a siege better than a single-tier force.
Diplomacy. Convincing a neutral neighbour to stay neutral, or persuading a city's locals to favour the attacker, can change the siege before the first arrow flies. See diplomacy.
Reconnaissance. Infiltration inside the target city can weaken its defenses ahead of the assault.
The Siege Battle
Once joined, a siege resolves on a dedicated battle map. Assault siege weapons, scaling ladders, and breach attempts at gates all have their place. Defenders use walls, towers, and the city garrison; attackers use numbers, mobility, and the strength of their best units.
Layered modifiers from the five-element, yin-yang, and eight-trigrams systems influence both unit and named-character matchups. A skilled defender with the right elemental affinity can hold a wall against a numerically superior attacker; a mismatched attacker can lose more troops than expected even when the numbers favour them.
Field Command
The player's role in a siege is partly direct command and partly delegation. Personal melee combat is still possible: the main character can join a wing, lead a vanguard, or duel a defender's champion. But the larger fight is shaped through orders to retainer-led wings, unit positioning, and timing of major actions like a wall breach or a feigned retreat. A clan with capable retainers can win sieges the player would lose on personal skill alone.

Common Bug Fixes and Quality of Life
Siege battles have been a focus area for fixes during early Early Access. Specific issues addressed include units becoming stuck outside invisible boundaries on siege battle maps, characters falling out of the playable area in combat scenes and being unable to fight, and unit pathing inside the city after a successful breach. Loading and frame-rate behaviour during sieges has also been on the developer's stated optimization list.
After the Siege
A successful assault brings the prefecture under the attacker's control. Loot, prisoners, and political consequences follow: defeated retainers may be recruited or held, defenders' clans may declare blood feuds, and the wider war state of the surrounding region shifts. A failed assault forces the attacker to retreat, recover, and either renegotiate or rebuild before another attempt.
