5 Military Metrics — Staff Scoring System
Rome had superior sustainability due to its established logistical network in Italy and maritime supply lines. The Visigoths relied on a plunder-based economy and inevitably faced supply shortages in prolonged operations.
Stilicho effectively used the professional Roman command structure to coordinate forces at Pollentia and Verona. Alaric, despite his charismatic leadership, had a clan-based command chain and could not compete with Rome at the strategic level.
The Visigoths initially gained initiative by crossing the Alps and advancing rapidly along the Via Postumia. However, Stilicho seized the advantage of time and space by surprising the enemy on Easter Sunday at Pollentia and maneuvering to encircle them at Verona.
Roman intelligence could track Alaric's movements; Claudian's poetry indicates Rome was aware of the Gothic advance. Alaric, in contrast, lacked sufficient information on Roman strategic decisions and misjudged Stilicho's peace offers.
The Roman army was superior in discipline, heavy equipment, and professionalism. The Visigoths' force multipliers were their speed, warrior spirit, and desire for plunder, but these factors proved insufficient against organized Roman resistance.

- ›Alaric's army suffered heavy losses at Pollentia but preserved its core force, maintaining the capacity to sack Rome in the future.
Defeated Party's Losses
- ›The Western Roman Empire repelled Alaric's invasion, preventing the total collapse of Italy and temporarily securing its borders.
- ›Rome failed to completely destroy the Visigothic threat; instead, it was forced to gain Alaric as an ally, deepening its dependence on barbarians.

Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Through diplomatic maneuvers, Stilicho pursued a strategy of using Alaric as an ally/mercenary rather than crushing him militarily. Alaric tried to extract concessions without fighting by exploiting Roman political divisions, but ultimately failed.
Intelligence Asymmetry
Rome was superior in foreseeing Alaric's intentions and movements; through spy networks and city reports, it was not caught off guard. Alaric could not decipher Stilicho's true intentions (especially the strategy behind peace offers), and this asymmetry contributed to his defeat.
Heaven and Earth
The Alpine passes and Via Postumia allowed Alaric's rapid advance, while the open terrain at Pollentia favored Roman cavalry maneuvers. The battle of Verona unfolded to Stilicho's advantage due to good use of terrain. The Visigoths, suffering from supply shortages in winter months, were disadvantaged by seasonal hardships.
Western War Doctrines
Delaying Action
Maneuver & Interior Lines
The Visigoths, with a mix of infantry and cavalry, were able to advance rapidly on Roman roads. However, Stilicho used interior lines to concentrate forces faster and caught Alaric at Pollentia. At Verona, he restricted Gothic mobility through encirclement.
Psychological Warfare & Morale
Alaric's troops were motivated by the desire to plunder rich Italy and had high loyalty to their leader. In the Roman army, while Stilicho's presence was a morale factor, the weakness of Emperor Honorius and political infighting in the Senate undermined overall motivation. Nevertheless, professional discipline prevented a morale collapse.
Firepower & Shock Effect
The Roman army excelled in creating shock effect through combined arms and cavalry charges. At Pollentia, Stilicho's cavalry assault shattered the Gothic lines, while at Verona, the encirclement operation caused psychological breakdown. The Visigoths' shock effect relied mainly on infantry mass and was ineffective.

Center of Gravity · Intelligence · Dynamism
Center of Gravity
Stilicho correctly identified the Schwerpunkt as the destruction of Alaric's mobile army in pitched battle and concentrated forces there. Alaric dispersed his center of gravity among plunder targets, failing to achieve strategic focus, which led to his battlefield defeats.
Deception & Intelligence
Stilicho deceived Alaric by attacking on Easter Sunday at Pollentia and using a feint encirclement at Verona. Alaric employed no deceptive strategy, relying solely on direct plunder and negotiation tactics.
Asymmetric Flexibility
Under Stilicho's leadership, the Roman army displayed doctrinal flexibility, switching between defense and attack as needed and quickly adapting to barbarian tactics. The Visigoths were rigidly tied to clan warfare traditions and struggled to adapt to organized Roman resistance.
Section I
Staff Analysis
Alaric's invasion of 401-403 was an asymmetric conflict between the Visigoths' mobility and plunder motivation and Rome's professional military strength. Stilicho, exploiting interior lines, won decisive tactical victories at Pollentia and Verona after the initial Gothic advance. Not destroying Alaric might seem a strategic error, but it was a rational decision given the cold war with the Eastern Roman Empire. For the Visigoths, the invasion, though a military failure, exposed Roman fragility and increased Alaric's bargaining power.
Section II
Strategic Critique
Alaric entered Italy with unclear strategic objectives; a plunder-focused campaign yielded no permanent territorial gains. Stilicho, on the other hand, failed to convert tactical victories into strategic success: Alaric's army survived to threaten Italy again. Stilicho's main error was increasing the Roman army's dependence on barbarian mercenaries and his policy of keeping the Visigoths as allies, which in the long term weakened Rome's military structure.
