Battle Overview

Date and Location

The Battle of Cassano, also known as the Battle of the Adda River, took place from April 26th to 28th, 1799 (April 16th-17th Old Style). It occurred along the Adda River in Lombardy, Northern Italy, involving key points such as Lecco, Vaprio, Cassano, and Verderio.

Outcome

The engagement resulted in a decisive victory for the Austro-Russian forces, led by Field Marshal Alexander Suvorov. This victory forced the French army, under Generals Schérer and later Moreau, into a significant retreat, leading to the occupation of the Cisalpine Republic by the Coalition.

Context

This battle was a crucial part of the Italian campaigns during the War of the Second Coalition. It occurred while Napoleon Bonaparte was engaged in Egypt, highlighting the broader European conflict and the strategic importance of controlling Northern Italy.

Strategic Context

War of the Second Coalition

The War of the Second Coalition (1798–1802) saw a renewed effort by European powers, including Great Britain, Austria, Russia, the Ottoman Empire, and others, to contain the expansion of the French Republic. Italy became a primary theater of operations.

Italian Campaigns

Following Napoleon Bonaparte's successful Italian campaigns of 1796-1797, French influence was widespread. However, the Second Coalition aimed to reverse these gains. The battles in Italy in 1799 were critical in determining the fate of the Italian republics established by France.

French Command Shift

The battle is notable for the change in French command. General Barthélemy Schérer, whose initial actions were indecisive, handed over command to the more capable General Jean Moreau shortly before the main engagements. This shift occurred amidst the French army's retreat following the defeat at Magnano.

Combatant Forces

Coalition Army

The Coalition forces comprised a combined Austro-Russian army under the overall command of Field Marshal Alexander Suvorov. The army was composed of approximately 48,000 to 50,000 soldiers, including Russian regulars, Cossacks, and various Austrian corps and divisions.

French Army

The French Army of Italy, initially under General Schérer and later General Moreau, numbered approximately 27,000 to 28,000 men. It was deployed along the Adda River, attempting to hold a defensive line against the advancing Coalition forces.

The Battle Unfolds

Suvorov's Strategy

Suvorov aimed to force a crossing of the Adda River, which offered a strong natural defensive position for the French. He concentrated his main forces for an assault while using diversionary actions to stretch the French lines. The crossing points were strategically chosen to disrupt the French deployment.

The Crossing

The battle involved multiple engagements over two days:

  • April 26th: Combat of Lecco - Bagration's Russian forces engaged French troops under General Soyez near Lecco. While a Russian victory, it was a minor engagement relative to the main battle.
  • April 27th: Vaprio & Cassano Engagements - The main Coalition effort focused here. Austrians under Ott and Zopf, supported by Cossacks, crossed the Adda at Vaprio, engaging Grenier's division. Simultaneously, Melas' Austrian forces assaulted Cassano, eventually capturing the bridgehead.
  • April 28th: Verderio Surrender - A French detachment under General Sérurier, isolated by the Coalition's crossings, was surrounded at Verderio by Vukassovich's forces and forced to surrender.

French Response and Retreat

Despite the initial French defensive advantages, Suvorov's coordinated attacks proved effective. Moreau, recognizing the compromised position and the loss of Cassano, ordered a general retreat. The French forces withdrew towards Milan and beyond, leaving garrisons in key fortifications.

  • Schérer's deployment was criticized for being too dispersed along the river.
  • Suvorov's crossing at Vaprio, though difficult, bypassed strong French positions.
  • The capture of Cassano by Melas' troops was crucial, threatening the French rear.
  • The surrender at Verderio sealed the fate of Sérurier's isolated division.
  • Moreau's tactical skill could not overcome the strategic disadvantage created by Suvorov's maneuvers.

Consequences and Losses

Casualties and Captured

The battle resulted in significant losses for the French army, while Coalition casualties were substantial but lower.

French Losses:

  • Killed and Wounded: Approximately 2,500 to 7,500 (estimates vary).
  • Captured: Approximately 5,000 soldiers, plus 27 cannons and 3 standards.
  • Total French losses estimated between 10,500 and 11,000.

Coalition Losses:

  • Killed and Wounded: Approximately 2,000 to 2,500 (estimates vary).
  • Total Coalition losses estimated between 4,886 and 6,200.

Territorial and Political Impact

The Coalition victory led to the recapture of Milan and the effective collapse of the Cisalpine Republic. The French were pushed back, opening the path for Suvorov's subsequent campaigns deeper into Italy and Switzerland.

Strategic Significance

The Battle of the Adda River marked a critical turning point in the 1799 Italian campaign. It demonstrated Suvorov's tactical prowess and significantly weakened the French position in Northern Italy, contributing to the overall momentum of the Second Coalition.
