5 Military Metrics — Staff Scoring System
Venice, with its maritime trade and vast financial resources, could finance a prolonged war, while Milan's economy weakened due to continuous conflict in Lombardy and its supply lines remained insecure despite Piccinino's deep raids.
On the Milanese side, Piccinino's experience and initiative were effective in sudden raids like Chiari, but Visconti's strategic indecisiveness and reluctance to grant full authority undermined command unity. Venice, by later bringing in a capable commander like Sforza, gained flexibility in command and control.
Venice managed to slow Milan's advance by defending fortified cities like Brescia and Verona; Sforza capitalized on timing to counterattack at Soncino. Milan failed to exploit critical timings, such as Piccinino's return from Romagna, and lost the initiative at the siege of Martinengo.
Piccinino, through his papal connections, received good intelligence on developments in Romagna, while Venice's communication network with Florence and other allies allowed it to anticipate enemy movements. However, Piccinino's Chiari raid exposed a gap in Venetian intelligence.
Francesco Sforza's charisma and military skill as a condottiero boosted the morale of Venetian troops and influenced other condottieri. On the Milanese side, Visconti's promises to Piccinino, such as Piacenza, were insufficient to motivate, creating distrust among the forces.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Venice attempted to diplomatically isolate Milan through alliances with Florence, but a clear strategy of winning without fighting was not evident. Sforza's mediation at Cavriana allowed Venice to end the war while gaining diplomatic points.
Intelligence Asymmetry
Milan, through Piccinino's personal networks, closely monitored developments in the Papal States and Romagna, while Venice used its commercial intelligence network to assess Milan's internal weaknesses. Ultimately, Venice better read the enemy's political fragmentation and gained an advantage.
Heaven and Earth
The Lombard plain and fortified cities in the Alpine foothills gave the advantage to the defender, while rivers (Adda, Po) were used as logistical and maneuver obstacles. Venice fortified cities like Brescia and Verona to blunt Milan's attacks; Piccinino's mid-winter raids were unsustainable due to seasonal conditions.
Western War Doctrines
Siege/Challenge
Maneuver & Interior Lines
Piccinino made a rapid return from Romagna to raid Chiari, trying to exploit the advantage of interior lines. In response, Sforza showed flexibility by shifting forces from Soncino to Martinengo, but his room for maneuver was constricted when surrounded by Piccinino.
Psychological Warfare & Morale
Sforza's joining the Venetian ranks had a positive psychological effect on the troops, while Piccinino's shifting loyalties and Visconti's broken promises led to a morale collapse in Milanese forces. The mediation at Cavriana reflects war fatigue.
Firepower & Shock Effect
Both sides used heavy cavalry and artillery, but lacked concentrated firepower to create decisive shock effect in pitched battles. Piccinino's surprise raid at Chiari briefly shocked Sforza's garrison, but Sforza's resistance limited this effect.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
For Milan, the strategic center of gravity was breaking Venetian positions at Brescia and Verona, while for Venice it was preserving the main army under Sforza and attriting Milan. Venice more accurately identified its Schwerpunkt and concentrated resources on the main threat area.
Deception & Intelligence
Piccinino surprised Sforza's garrison at Chiari by returning unexpectedly from Romagna, and deceived Sforza by surrounding him at Martinengo. However, Venice neutralized Piccinino through diplomatic maneuvers, exploiting the possibility of Sforza switching sides.
Asymmetric Flexibility
Both sides were inclined toward maneuver warfare, consistent with the dynamic nature of condottieri armies. Venice adapted by employing different commanders like Sforza, while Milan remained overly dependent on Piccinino, lacking flexibility. The return to the status quo with the Peace of Cremona indicates neither side could achieve a decisive result.
Section I
Staff Analysis
The Fourth Lombard Campaign was part of the struggle for hegemony in Northern Italy between the Republic of Venice and the Duchy of Milan. Initially, Milan gained the upper hand with an aggressive offensive under Piccinino, besieging Brescia and threatening Verona, but the balance shifted when Venice hired Francesco Sforza. Sforza's victory at Soncino turned the tide, though Piccinino's raid at Chiari prolonged the war. Both sides relied heavily on condottieri and mercenaries, making commander loyalty and skill critical. Ultimately, Venice partially achieved its strategic goals and maintained its positions through the peace agreement.
Section II
Strategic Critique
The Venetian High Command made the correct decision to hire Sforza in time, but the vulnerability at Chiari indicated errors in intelligence and garrison placement. On the Milanese side, Visconti's failure to fully support Piccinino and his rejection of the Piacenza offer in favor of approaching Sforza was a strategic mistake, as it demotivated Piccinino and hastened the war's end. Excessive reliance on mercenaries led both sides to act according to personal interests.
