Florentine–Milanese War (First War, 1390–1392) vs Florentine–Milanese Wars (Visconti Wars)

The Florentine army, despite its mercenary composition, adapted quickly to changing conditions thanks to Hawkwood. Milan, with its rigid command structure, lacked such flexibility.

Florence adopted a flexible doctrine relying on mercenary captains' initiative, exemplified by Hawkwood's feigned retreats. Milan's doctrine was more rigid and centralized but compensated by Visconti's diplomatic adaptability. Florence couldn't adapt strategically after losing allies.

Attrition War — Both sides opted to wear each other down through reliance on fortified positions and limited offensives, rather than seeking to annihilate the enemy in a decisive pitched battle.

War of Attrition — Both sides attempted to exhaust the opponent through diplomatic encirclement and economic pressure rather than decisive battle. Pitched battles were rare; Casalecchio constituted the exception after Florence's allies defected.

For Florence, the recapture of Padua was the center of gravity, and forces were effectively concentrated on this objective. Milan, on the other hand, kept its main strength in Lombardy to neutralize Florence's direct threat.

Visconti correctly identified Florence's alliance network as the center of gravity and dismantled it. Florence misjudged Milan's main strength by directly attacking the city and failed. Visconti's death instantly eliminated Milan's center of gravity.

Hawkwood surprised Milanese forces through feigned retreats and deceptive maneuvers, particularly when he extricated his army from encirclement at a critical moment.

Gian Galeazzo masterfully employed deception: negotiating a treaty with Florence only to expel Florentines immediately and plotting a coup in Bologna. Florence's disingenuous denial of mercenary buildup deceived Siena briefly but failed long-term.

Due to the warfare style of the period, shock elements such as heavy cavalry and crossbows remained limited; the war relied more on siege and positional warfare. Neither side achieved a decisive shock effect.

Both sides relied on heavy cavalry and archers but achieved no decisive shock effect. At Casalecchio, disciplined Milanese infantry charges broke Florentine lines. Hawkwood's feigned retreats succeeded in the first war but no overwhelming firepower advantage emerged.

The terrain, especially the marshes of the Po Valley and fortified cities, limited maneuverability. The halting of operations during winter months defined the campaigning seasons.

Northern Italy's geography of rivers and fortified cities favored the defense, while Milan's central position in the Lombard plain provided an operational advantage. The plague (heavenly factor) killed Visconti, dramatically ending the war. Florence's Apennine barrier offered protection but not complete isolation.

Gian Galeazzo Visconti better analyzed Florence's internal political dynamics and allied weaknesses but failed to predict Hawkwood's sudden maneuvers. Florence, for its part, could not fully assess Milan's resources and resolve.

Visconti held superior knowledge of rivals' internal affairs; for instance, his coup plot in Bologna demonstrated deep intelligence penetration. Florence remained unaware of Visconti's secret negotiations with Pisa and Siena, precipitating alliance collapse.

Hawkwood exploited interior lines by extricating the beleaguered Florentine army in a rapid and disciplined retreat. Milan, burdened by its heavy logistical tail, was slow to counter-attack.

Milan effectively applied the principle of interior lines, shifting forces from Verona to Tuscany. Florence lagged in maneuver due to mercenary logistics and poor coalition coordination. Hawkwood's individual efforts could not compensate.

Hawkwood's legendary leadership kept Florentine morale high, preventing disintegration during the difficult retreat. In Milan, Gian Galeazzo's ambition and central authority suppressed low-level morale fluctuations.

Morale in Florence initially surged under the pro-war faction, but allied losses and prolonged war led to psychological breakdown. Visconti's charismatic leadership and steady gains maintained high morale in Milan, while siege panic gripped Florence.

During the war, Florence gained strategic advantages without battle by persuading Ferrara to defect and liberating Padua. Conversely, Milan gathered strength without fighting after the war by securing diplomatic gains with France and the Empire.

Gian Galeazzo Visconti achieved strategic superiority without battle by diplomatically isolating Florence. Drawing Siena into alliance and seizing Pisa encircled Florence. Florence sought German support to balance Visconti but failed.
