Italian campaigns of the French Revolutionary Wars

The Italian campaigns of the French Revolutionary Wars (1792-1802) were a series of conflicts fought principally in Northern Italy between the French Revolutionary Army and a Coalition of Austria, Russia, Piedmont-Sardinia, and a number of other Italian states.

First Coalition (1792-1797)

In autumn 1792, several European powers formed the First Coalition against France. The first major operation, the annexation of Nice by some 30,000 French troops, was reversed when the Republican forces were withdrawn to deal with a revolt in Lyon, triggering a Piedmontese invasion of Savoy in mid-1793. With the suppression of the revolt in Lyon, General Kellermann managed to push back the Piedmontese with just 12,000 troops, winning engagements at Argentines and St Maurice in September and October of the same year.

The conflict soon escalated with Austrian and Neapolitan forces being mobilised for an invasion of southern France to recover Nice and strike into Provence. The Allied forces were reinforced to some 45,000 Austrians, Piedmontese, and Neapolitans supported by the Royal Navy. Before the Allies could launch this assault the new commander of the French Army of Italy launched the Saorgio Offensive, which was planned by the army's artillery commander, General Napoleone Buonaparte. This two-pronged French offensive drove back the Allied force, despite their strong positions and firmly captured the mountain passes that led into Piedmont. A new offensive, again devised by General Bonaparte, was similarly successful despite its more complicated nature, calling for the co-ordination of the Army of Italy and the Army of the Alps.

Further assaults on the Allied positions were called off under orders from war minister Carnot who was concerned about supply lines being cut by rebels behind the front. The commanders on the front were unhappy about this decision, but appeals were interrupted by the overthrow of the Committee of Public Safety and its leader, Maximilien de Robespierre (28 July 1794). During the chaos that ensued in the French army the Allies launched an assault on Savonna. Ignoring Carnot's orders, the command of the Army of Italy launched a counter-offensive and secured supply routes to Genoa following victory at the First Battle of Dego. Following this the French consolidated the front and awaited further opportunity.

The main focus of the war then shifted north to the Rhine, until June 29, 1795, when the Austrians launched an attack against the depleted and poorly supplied Army of Italy. Nominally 107,000-strong, the Army of Italy could only manage to field an effective force of about 30,000. Kellermann, who had resumed command, appealed to Carnot for reinforcements. Instead, General Bonaparte was appointed to the general staff where he devised a third plan for an attack towards Vado and Ceva. Kellermann was replaced by General Schérer soon after and he carried out the attacks, gaining victory at Loano.

Bonaparte's war

Following a brief respite in hostilities Schérer resigned and Bonaparte was appointed commander-in-chief on March 2, 1796. The motives for Bonaparte's appointment were most likely political. Bonaparte had shown himself to be highly ambitious and had made quite a name for himself following his meteoric rise during the Siege of Toulon in 1793. By placing him in command of the Army of Italy, Bonaparte was being relegated to obscurity. Of the Republic's thirteen principal field armies, the Italian force was the most neglected and was in terrible condition when Bonaparte arrived.

Bonaparte launched attacks almost immediately after he arrived on the front on March 27. His 37,000 men and 60 guns were facing more than 50,000 Allied troops in the theatre. His only chance of support came from Kellermann's Army of the Alps, which was occupied by a further 20,000 Allied troops. Bonaparte had no chance of gaining reinforcements as the Republican war effort was being concentrated on the massive offensives planned on the Rhine.

At Montenotte Bonaparte defeated the Austrians and fought a second engagement around Dego soon after. Following these battles he launched an all-out invasion of Piedmont and won a further victory at Mondovì. The Armistice of Cherasco between France and Piedmont was concluded on April 28. In all it had taken Bonaparte two weeks to defeat Piedmont, which had been at war for over three years. In total during the lightning campaign French losses were 6,000 compared with more than 25,000 for the Allies.

Bonaparte reorganised his newly enthused army following the short let-up in operations that followed Piedmont's defeat. Following this he manouevred his army into more opportune positions along the Po River. A small French victory at Codogno led to a retreat by Coalition forces across the Adda River. At the river, the Austrian army of General Beaulieu was defeated in the Battle of Lodi on May 10.

The Army of Italy was now reinforced to almost 50,000 and Bonaparte continued the offensive, striking at Austrian forces mobilising in the vicinity of the fortress of Mantua. A series of minor Coalition defeats resulted in the garrison at Mantua being reinforced to 12,000. Placing Mantua under siege, Bonaparte then led a French division south to invade and occupy Tuscany and the Papal States, defeating Papal forces at Fort Urban. Next he turned north and with 20,000 men defeated some 50,000 Austrians under Field Marshal Wurmser at the battles of Lonato and Castiglione. The Austrian commander was forced back into the Alps.

Wurmser was reinforced once again to compensate for some 20,000 losses sustained in the past two months and made an attempt to relieve the siege of Mantua. Some 45,000 Austrian troops were left behind to guard against any new French offensive whilst the main body of the Austrian army moved on Mantua. At Rovereto Bonaparte devastated the Austrians on September 4 and was then well-placed to strike at the rear of Würmser's army. Reacting slowly to this new threat the Austrian was defeated soundly at the Battle of Bassano where his army was reduced to just 12,000. These he rapidly marched towards Mantua, but became trapped there by General Masséna's advance party.

Additional Austrian forces arrived whilst Bonaparte's army was weakened by disease and his supply lines threatened by rebellion. Government political commissars, especially Cristoforo Saliceti, brutally put down the uprisings, but the French position was weakened. To stabilise the situation Bonaparte created the Transpadane Republic and the Cispadane Republic.

Following this a new Austrian commander, Joseph Alvinczy, arrived and attempted yet another relief of Mantua. Bonaparte drove back Alvinczy, but his counter-offensive was seriously hampered by the defeat of one of his subordinates. Alvinczy held off a French attack at Caldiero on November 12 and Bonaparte was forced to withdraw. What followed was the famous three-day Battle of Arcole in which Bonaparte won an important and surprising victory against Alvinczy.

Next both forces were reinforced before Alvinczy launched another attack in January. In an even more impressive victory, Bonaparte defeated this renewed assault at Rivoli, inflicting some 14,000 casualties. Soon after Mantua finally fell to the French, making it possible for the French to continue their advance eastwards towards Austria. After a brief campaign during which the Austrian army was commanded by the Emperor's brother, the Archduke Charles, the French advanced to within 100 miles of Vienna, and the Austrians asked for a suspension of hostilities. Bonaparte's campaign, therefore, was undoubtedly the most important in bringing an end to the War of the First Coalition.

econd Coalition (1799-1800)

The second phase of the war in Italy began in 1799 as part of the War of the Second Coalition and was different from the first in that Russian forces participated in the campaign. However, at the beginning of the conflict the Russians were yet to arrive.

Some 60,000 French troops under Schérer faced off against an equal number of Austrians. An additional 50,000 Russians were expected to arrive shortly. The French were occupied with the pacification of Naples and this halved their effective strength to face the Austrians. In order to avoid a completely untenable situation arising, Schérer attacked as soon as possible in an attempt to preempt Austrian attacks.

Austrian commander Pál Kray defeated the French at Verona and Magnano in late March and early April. Schérer retreated back and left a small detachment of 8,000 in several forts. The Austrian commander, Michael von Melas, was slow to pursue the retreating French and was soon replaced as overall Coalition commander in the theatre by the brilliant Field Marshal Alexander Suvorov.

Schérer too was soon replaced by General Moreau, a man of greater fame and prestige. The French defeat at the Battle of Cassano on April 26 was followed by withdrawal from Lombardy and an overall unfavourable situation for the French. General Macdonald's army returned from Naples to support Moreau.

An initial Allied attack across the Po failed on May 11. Moreau's army was in tatters with just 9,000 men remaining. An attempted counter-attack was beaten back by Russian General Petr Bagration. Suvorov soon occupied Turin and proclaimed the restoration of Piedmont to its king.

The Army of the Alps engaged the Austro-Russian forces in a series of minor skirmishes, but did not come to the rescue of the Army of Italy. Suvorov overran a number of French garrisons and continued his relentless advance. Macdonald engaged Suvorov in the Battle of the Trebbia and was crushed. Macdonald retreated with the remnant of his army to Genoa whilst Suvorov reached Novi. The Austrian high command, the Aulic Council, ordered a halt to Allied offensives whilst the French garrisons of Mantua and Alessandria were overrun (see siege of Mantua and siege of Alessandria). Soon after this Moreau was dispatched to the Rhine and Joubert was sent to command the Army of Italy.

Suvorov, acting under orders from the Coalition high command, paused to gather his strength for an offensive in Autumn. On August 9, the French launched offensive of 38,000 men called the Battle of Novi. The offensive was thoroughly defeated by Suvorov, and resulted in the death of Joubert. Moreau, who had yet to depart for the Rhine, seized the initiative and led the survivors back to Genoa and began preparing a defence of the city.

However at that time the Allied high command in Vienna ordered Suvorov to move out of Italy and concentrate on breaking through the Swiss front. The respite this gave the reeling Army of Italy led to a turning point in the war. Melas, who resumed command of Coalition forces in Italy, now almost exclusively Austrian, paused the offensive and consolidated his forces, now that the Russians had been removed from Italy.

By the spring of 1800 Russia had withdrawn entirely from the Coalition. The situation in Italy, however, was still very much on the side of the Coalition. Melas had some 100,000 men under his command, opposed by just 50,000 French troops who were thoroughly dispersed. The Allies prepared for a thrust into southern France and across the Rhine, much further north. Melas moved forward slowly, laying siege to Genoa and halted his advance elsewhere.

It was at this time that the First Consul of France, Napoleon Bonaparte, led his Reserve Army through the Great St Bernard pass with the aiming of relieving Masséna in the Siege of Genoa, who was threatened by severe food shortages resulting from the combination of encirclement on land and naval blockade by the British.

Genoa fell before the First Consul could reach it. He concentrated his army and struck at the Austrians in an attempt to strike them before they too concentrated their forces again. The Reserve Army fought a battle at Montebello on June 9 before the main confrontation at Marengo. The consul was almost defeated here until General Desaix made a timely arrival with reinforcements and drove back Melas, thus turning a French rout into a French victory. In this counter-attack Desaix was killed, but Bonaparte later honoured him with monuments commemorating his bravery and his name has the place of honour on the face of the Arc de Triomphe, which was erected to celebrate Napoleon's victories.

Marengo was the last major engagement on the Italian front during the Revolutionary Wars. Following it the massive Battle of Hohenlinden brought the Austrians to the negotiating table and the war ended shortly after.
