The Flow of Priority (Right of Way)
A visual diagram explaining the core principles of priority in a longsword exchange, based on the official FEBUS rules.
Phase 1: Gaining Priority
An exchange begins when one fencer takes the initiative with a valid offensive action.
Simple Attack
A committed, uninterrupted offensive action with the arms extending towards an open target, supported by footwork. This establishes priority. Even a technically imperfect attack must be tackled.
Compound Attack
An attack initiated with feints to provoke a parry, creating a new opening. Priority is maintained if the action is continuous and threatening.
Attack on Blade
An attack that first takes control of the opponent's blade (e.g., a Beat Attack or a Bind) to create a safe opening for the final offensive action.
All attacks must include forward motion - never backwards or stationary.
Phase 2: Responding to the Threat
Once an attack has priority, the defender must respond. Their choice determines the outcome.
Correct Response: Parry & Riposte
The defender correctly parries the attack and immediately launches a riposte without hesitation. Priority is transferred to the defender for the riposte. The riposte may be direct, indirect, or compound, but any remise must hit one tempo before the final action of a compound riposte.
Alternative Response: Counter-Attack
Counter-attacks can be valid if they result in a clean hit (no double). This includes properly timed stop-hits, counter-attacks with opposition, or successfully avoiding the opponent's attack. If both fencers are hit, priority remains with the original attacker.
Phase 3: Special Conditions & Resolutions
Certain actions can preempt or alter the flow of the exchange.
Langort (Point in Line)
A static threat with the point aimed at the opponent, established before the opponent's attack begins. An attacker must first deflect the blade before their own attack can gain priority. Running onto an established point is a fault.
Attack in Preparation
An attack that takes priority by exploiting the opponent's preparation (e.g., a wide wind-up, a step without extending the sword, or a grip adjustment).
Stop Hit (Coup d'arrêt)
A counter-attack that hits before the opponent begins the final movement of a compound attack. Timing is critical for the Stop Hit to gain priority.
