5 Military Metrics — Staff Scoring System
L'Aquila's walls and access to local resources allowed it to withstand a prolonged siege, while the Neapolitan army depended on supply lines, and winter conditions severely disrupted its logistics.
Braccio's unified command initially gave Naples speed and cohesion, but his death caused an abrupt collapse of the chain of command; the coalition, despite divided leadership, managed coordination under the common threat.
The mountainous location of L'Aquila provided a natural defensive advantage that prolonged the siege; the coalition's relief forces arrived at the perfect moment, catching the Neapolitan army off guard.
The coalition, aware of Naples' plans, fortified the city in advance and concealed the movements of the relief army; Naples failed to estimate the enemy's true strength and timing, suffering an intelligence failure.
The Neapolitan army's professional condottieri units were superior in experience and offensive capability; however, the city's walls and allied infantry provided decisive defensive resilience.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Naples used diplomatic pressure and threats to seize the city without a fight, but could not break the will of the L'Aquila populace; the coalition gained moral superiority by securing external support without immediate battle.
Intelligence Asymmetry
Through spies in the Neapolitan court, the coalition learned Braccio's strategy and took countermeasures; Braccio underestimated the enemy's alliance network, leading to a flawed risk assessment.
Heaven and Earth
The harsh Italian winter and mountainous terrain wore down the Neapolitan army during the siege; L'Aquila's high position offered early warning and a defensive advantage.
Western War Doctrines
Siege/Challenge
Maneuver & Interior Lines
Naples tried to isolate the city with a rapid siege, but mountainous terrain limited maneuverability; coalition forces used interior lines to concentrate in time.
Psychological Warfare & Morale
The high morale of the Neapolitan army instantly collapsed with Braccio's death; the city population's psychology of homeland defense and religious motivation heightened their resistance.
Firepower & Shock Effect
The Neapolitan heavy cavalry charges were absorbed by the city's walls and failed to create shock; the coalition's sudden counterattack, coupled with the enemy commander's death, proved decisive.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
Braccio chose to breach the city walls as his main effort but ignored the enemy relief force; the coalition, at the critical moment, redirected its center of gravity against the Neapolitan main camp, achieving victory.
Deception & Intelligence
The coalition concealed the arrival of the relief army, achieving surprise; Braccio attempted feint attacks to take the city but was unsuccessful.
Asymmetric Flexibility
Naples followed a standard siege strategy, while L'Aquila wore down the enemy with guerrilla tactics and sorties, displaying asymmetric flexibility.
Section I
Staff Analysis
The 1423-1424 War of L'Aquila was a siege and field battle fought between the Kingdom of Naples' condottieri army and the allied forces of L'Aquila and northern Italian states in a mountainous terrain. Braccio da Montone's Neapolitan army initially moved swiftly to isolate the city, but winter conditions and the city's resistance prolonged the siege. The timely arrival of the coalition's relief army and Braccio's death in battle led to the immediate collapse of the Neapolitan forces. The war underscores the risks of reliance on mercenaries during the condottieri era and the critical importance of logistics.
Section II
Strategic Critique
Braccio da Montone correctly identified L'Aquila as a strategic objective but underestimated the city's resilience and the allied response. His failure to allocate sufficient engineering resources to accelerate the siege and his decision to continue operations during winter were mistakes. The disintegration of his army after his death shows that the entire campaign depended on his person. The coalition, by contrast, successfully established an intelligence and diplomatic network for timely intervention, but its multi-headed command structure prevented full exploitation of the post-victory advantage.
