5 Military Metrics — Staff Scoring System

Sustainability Logistics43vs78

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.

Command & Control C263vs42

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.

Time & Space Usage66vs47

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.

Intelligence & Recon56vs43

Louis gathered intelligence through diplomacy with Italian states and an effective spy network. Naples had poor reconnaissance and was surprised at Capua.

Force Multipliers Morale/Tech79vs34

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.

Asian Art of War

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.

Western War Doctrines

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.
