5 Military Metrics — Staff Scoring System
Hungarian forces faced logistical challenges operating far from home, while Naples had easy access to local resources. However, the Hungarian army's disciplined supply system and use of gold purchases mitigated local resistance.
Louis' centralized, authoritarian command structure with clear objectives and strict discipline was effective; Naples suffered from a fractured command due to Joanna's rivalry with Louis of Taranto and baronial disloyalty.
The Hungarian army's rapid winter march caught the enemy off guard, seizing initiative. However, the outbreak of the Black Death and extended supply lines forced an early withdrawal. Naples failed to utilize defensive depth.
Louis gathered intelligence through diplomacy with Italian states and an effective spy network. Naples had poor reconnaissance and was surprised at Capua.
The combination of Cuman horse archers and heavy cavalry, along with disciplined German infantry, provided tactical superiority. Naples' low morale and baronial betrayal compounded this advantage.

Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Louis declared he would not fight Italian cities, purchasing supplies with gold, thereby minimizing resistance. This psychological and diplomatic strategy weakened the enemy without battle.
Intelligence Asymmetry
Hungary had good intelligence on Naples' court intrigues and baronial disloyalty, exploiting the legitimacy vacuum after Andrew's murder. Naples misjudged the Hungarian army's speed and route.
Heaven and Earth
Crossing the Alps in winter surprised the Neapolitans. The open terrain at Capua favored Hungarian cavalry maneuver. The Black Death appeared as a natural calamity that curtailed the campaign's duration.

War of Annihilation
Maneuver & Interior Lines
Despite lacking interior lines, Louis moved his forces rapidly from Hungary into Italy, advancing to Capua without resistance. Naples failed to concentrate forces and reacted slowly.
Psychological Warfare & Morale
The Hungarian army had high morale driven by their king's personal leadership and a cause of revenge. In Naples, suspicion over Andrew's murder, baronial distrust, and Louis' disciplined approach collapsed the will to fight. Clausewitzian friction heavily affected Naples.
Firepower & Shock Effect
The combined shock of Hungarian heavy cavalry and Cuman arrow barrages shattered Neapolitan infantry at Capua. Louis effectively synchronized firepower with maneuver for tactical success.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
Louis correctly identified the Neapolitan capital and royal army as the enemy's center of gravity, concentrating his forces there. Naples dispersed its forces across static defenses, diluting combat power.
Deception & Intelligence
Louis' declaration of peace towards Italian cities was a diplomatic deception to isolate Naples. Naples, plagued by poor intelligence and treason, could not execute effective counter-deception.
Asymmetric Flexibility
The Hungarian army seamlessly transitioned from a pitched battle at Capua to siege operations and occupation governance. Naples persisted with a static defense doctrine, lacking guerrilla or hit-and-run adaptation, though showed diplomatic flexibility in recovering after Louis' departure.
Section I
Staff Analysis
Louis I conducted a successful campaign against Naples in 1347 with superior command and a disciplined, largely mercenary army. His strict anti-plunder policy, paying for supplies in gold, ensured neutrality from Italian city-states. At Capua, he combined Cuman horse archers' ranged mobility with a heavy cavalry shock charge to rout the Neapolitan knights. Logistically challenging, the campaign was sustained through local purchases. In contrast, Naples under Joanna suffered from weak leadership, factionalism, and low morale, failing to mount an effective defense. Louis of Taranto's army, though comparable in numbers, was tactically outclassed. Despite being forced to withdraw due to the Black Death, Louis achieved most strategic objectives.
Section II
Strategic Critique
The Hungarian high command executed a swift and decisive campaign under Louis, but the failure to secure the occupation with sufficient garrisons was a major mistake. The plague was a harsh but real factor; however, the temporary occupation prevented a lasting hold. Nevertheless, Charles of Durazzo was avenged, and groundwork laid for a later pro-Hungarian coup. Naples' command squandered its forces through internal intrigue and legitimacy crises stemming from Andrew's murder. Accepting pitched battle at Capua without effective cavalry deployment was a tactical blunder. Ultimately, Louis' resolve and discipline, combined with Naples' weaknesses, delivered victory.
