The Battle of Cassano (French: Bataille de Cassano, German: Schlacht bei Cassano) was fought in 1799 from 27 to 28 April (O.S.: 16 to 17 April) near Cassano d'Adda, which about 28 km (17 mi) ENE of Milan. The clash is part of the battle of the Adda River (Russian: Сражение на реке Адда, German: Schlacht an der Adda) or the so-called forcing of the Adda, which on the first day of 26 April (O.S.: 15 April) resulted in a minor victory for the Russians under the Count Suvorov over Barthélemy Schérer's French forces at Lecco. Then, on the second day, Suvorov's Austrians and Cossacks prevailed over Jean Moreau's army, who replaced Schérer as supreme commander, and trapped his isolated division on the third. The action took place during the War of the Second Coalition, as part of the larger conflict known as the French Revolutionary Wars.
The battle of the Adda River was four separate combats. Lecco was a victorious combat for Suvorov's Russians, but it contributed little to resolve the entire battle along the Adda. The key engagement on 27 April was the combat at Vaprio d'Adda (at the end there were about 11,000 Austrians and Cossacks and 7,000 French), which is north of Cassano; and on the same day, at Cassano itself, the Austrians successfully stormed the bridge-head fortifications—Moreau was thrown back everywhere. The French detachment cut off by the combat of Vaprio was afterwards surrounded at Verderio by Josef Philipp Vukassovich, who overcame the weakest French defenses in Brivio.

Background
While General Napoleon Bonaparte campaigned in Egypt, the Second Coalition launched an invasion of French-occupied Italy. General of Division (MG) Barthélemy Schérer fought inconclusive actions the Austrians at Pastrengo, Verona, and Legnago on 26 March 1799. Feldmarschal-Leutnant (FML) Pál Kray and his Austrians then defeated Schérer at the Battle of Magnano on April 4. This defeat forced the French army into a long retreat. Attempts by Schérer to hold the lines of the Mincio and Oglio rivers failed when an Austrian force led by FML Josef Vukassovich turned his northern flank. Austria's Russian allies, led by Suvorov, soon began appearing at the front.
Suvorov took the fortress of Brescia without a fight. The Cossacks seized Bergamo and Bagration's vanguard pushed back the French outposts in Caprino Bergamasco.
When Field Marshal Suvorov joined the allied army, he took over the top command from Kray, though the latter had just been promoted to Feldzeugmeister. The arrival of General of the Cavalry Michael von Melas displaced Kray the top Austrian field command. Therefore, Kray was assigned to capture the fortress of Mantua, while Melas and Suvorov pursued the French. The siege of Mantua lasted from April until the garrison surrendered on 28 July.
Forces
French Army
Schérer deployed the divisions of MGs Paul Grenier, Claude Victor, Jean Sérurier (each of the three divisions had around 8,000 men), and Pierre de Laboissière (4,000 men; from Villa Pompeiana to the Po River) to defend the line of the Adda River. Victor's and Grenier's divisions included the Polish and Helvetic legions.
Coalition Army
The Russian advance guard was led by Pyotr Bagration (3,000 men), and the corps by Andrei Rosenberg (9,000 men on the way from Caprino to Lecco). The Austrians still made up the bulk of the allied army: 20,000 Russians and 30,000 Austrians at Suvorov's disposal, according to Christopher Duffy. There were the following formations of irregular Cossack cavalry: the regiments of Adrian Denisov , Pyotr Matveyevich Grekov , and Molchanov: a total of 1,500 men. The Austrian division commanders were FML Peter Ott, FML Johann Zopf (each of the two divisions had around 5,000 men), General-Major Franz de Lusignan (acting commander for FML Michael von Fröhlich), FML Konrad Valentin von Kaim (Kaim and Fröhlich's joint force was 13,000 men), and Josef Philipp Vukassovich (7,000 men). Michael von Melas was sent to Cassano and was nominally commander of all Suvorov's Austrian forces.
Battle
Schérer relied on the advantages of his defensive position, as the river is wide and deep, has very few fords and in its upper part, as far as Cassano, flows in elevated steep banks, of which the right, occupied by the French, prevails over the left. But Schérer failed to take all the advantages of this natural defensive line. He scattered 28,000 men over 100 km along the river, nowhere having sufficient forces for defense. Suvorov separated Hohenzollern with 6,000 men to Pizzighettone and Seckendorff to Lodi to conduct diversionary operations, and with a main body of 35,000 to 36,000 men concentrated offensive on the bulk of the French line. The disposition for April 26 instructed Ott's division to organize the crossing at Capriate San Gervasio.
The battle was divided into three different clashes: the combat of Lecco, where Suvorov sent Bagration's Russians, most likely as a distraction; the combats near Trezzo sull'Adda and Vaprio d'Adda, where mostly Austrians were concentrated, and these battles proved decisive for the allied victory; and the combat around the fortified position of Cassano, where Melas' Austrians had been sent, they would go to the rear of the French at an end of battle; it will be by the time the fight at Vaprio is won by the Allies, however, this manoeuvre will force Moreau to retreat in a different direction.
Lecco
On the night of April 26, Prince Bagration reported that Lecco was heavily occupied by the French. Assuming the entire division of Sérurier there, Suvorov stopped Vukassovich at Caprino and the entire Russian division in order, if necessary, to support Bagration, who moved to Lecco with his regiment of jaegers, Lomonosov combined battalion and all Cossack regiments.
On the same date, Bagration, following a mountain gorge, at 8 o'clock in the morning met a small advanced French unit 2 km from Lecco, overturned it and approached the city, occupied by 4 battalions, 1 squadron (108th demi-brigade) under the command of Brigadier General Soyez; on the right bank of the Adda, opposite the bridge dismantled by the French, there were 6 guns on the heights. The Cossacks surrounded the stone-fortified city; a company with 2 licornes was placed against the bridge. Bagration divided the rest of the forces into 3 columns; one went straight to the city, the other bypassed, and the 3rd remained in reserve. The first two columns broke into the city, reached the square, but here they met stubborn resistance; Bagration brought a reserve into action and drove out the French, who, having left the city, scattered thick chains of chasseurs over the surrounding mountains and vineyards. From the heights, they noticed the numerical insignificance of the Russian detachment, went on the offensive, drove the Russians out of the city and began to bypass them with mountains on the right in order to cut off the retreat along the gorge. Bagration also covered himself with a dense chain of jaegers and dismounted Cossacks, sending to Rosenberg to ask for help.
Mikhail Miloradovich took out carts and rushed with Dendrygin grenadier battalion at a time when the French were flanking Bagration from the village of Germanedo. Being higher in rank than Bagration, he refused to accept command over the detachment, saying:
"There is no place to be considered ranks here."
and left Bagration to finish the job, which he had begun so successfully. The arriving battalion stopped the detour movement of the French; soon 2 battalions approached with the head of the division, Povalo-Shveikovsky, and the city was again occupied by the Russians; the French cavalry, crashing into the Russian column, was slaughtered. Meanwhile, the French, standing on the right bank of the Adda, began to cross in boats between Olginate and Brivio, to the rear of the Russian troops. Due to the difficulty of moving along the road to the gorge, the Russian artillery was left under the cover of a battalion (Baranovsky); the artillery met the French troops, and General Shveikovsky himself rushed there; the French were overwhelmed. The battle lasted 12 hours, from 8 am to 8 pm. The French fought hard, but left 100 prisoners behind, the number of killed and wounded is unknown; the Russians lost 385 men KIA or WIA; Bagration was among the wounded. It was impossible to start the crossing on the same day. However, the Russians managed to seize the bridge.
Meantime, Vukassovich approached Brivio, which was very weakly occupied, and began to arrange a crossing, and therefore the Russians moved away from Lecco, settling down for the night between Lecco and Brivio. Waiting for a report on the outcome of the battle on the right flank, Suvorov postponed the crossing at San Gervasio until the night of April 27. In all, 4,993 Russians including approached reinforcements, and 5,000 French participated in this clash.
Eventually the French withdrew on rafts northwards from Lecco territory (night of 27-28 April), knowing that Adda had already been forced by the Allies elsewhere and that the road behind them would soon be cut off.
Vaprio & Cassano
On April 27, on orders from Paris, Schérer, completely out of his depth, handed over army command to the more capable MG Moreau. When news of the change in command reached Suvorov he remarked:
Here too I can see the hand of Providence. There would have been no great glory in fighting it out with a charlatan. But to beat Moreau — that would be something worth doing.
At midnight on 27 April, Ott began building a pontoon bridge at Trezzo. The point for crossing was very inconvenient from the theoretical point of view: the steepness of the bank made it difficult to launch the pontoons on the water; the winding, fast flow of the river and the rocky bottom prevented the convenience of the bridge; but the French did not pay attention to this inconvenient place (the 2nd Battalion of the 33rd Line Demi-Brigade, left by Sérurier at Trezzo, occupied the castle but had no posts on the bank itself), the night darkness covered the work, the river was not wide, so that only 7 pontoons were needed. The pontooner officer reported the impossibility of making a bridge at this place. Then Marquess Johann Gabriel Chasteler, chief of staff, who had already learnt Suvorov's notions of intransigence in overcoming obstacles, arrived at the crossing point and took decisive measures.
It was already tough for the French to rectify the situation: the Russians and Austrians surreptitiously pass through Adda in the centre of the French position near San Gervasio, in a places considered unsuitable for crossing. A number of jaegers and volunteers from Nádasdy battalion crossed by boat and occupied the right bank to secure the bridge. They started putting in pontoons; the work was done in perfect silence, and by daybreak the bridge was ready. Only in the morning did the French battalion notice its blunder, but it was too late: 6 companies of d'Aspre's jaegers and several Cossack sotnias crossed the bridge, followed by Ott's division, then Denisov, Molchanov, and Grekov Cossack regiments, which arrived very quickly from Lecco; at last Zopf's division also moved. The Cossack regiment of Denisov overtook the French battalion from the rear; pursued by Ott's head battalions, it had barely time to retreat. Suvorov was at this point crossing the river with might and main across the Trezzo sull'Adda Bridge and its vicinity. At the same time Allied forces crossed at Brivio; but, nevertheless, Moreau gave orders for the immediate concentration of forces. Grenier and Victor were bringing troops from the south. General of the Cavalry Melas having the divisions of Fröhlich and Kaim stormed the French positions at Cassano in the morning: the eastern bank of the river was held by the French demi-brigade, to the aid of which Victor already rushed.
According to some archival documents, it can be assumed that Suvorov himself was at Vaprio and hurried the crossing. He was able to concentrate around 20,000 soldiers there, while Moreau concentrated 15,000; Moreau had no doubt that the main Coalition's attack was under way here; he rode to the battlefield and almost fell into the hands of the Cossacks, who had already reached Inzago. Grenier was ordered to take position between Vaprio and Pozzo d'Adda. Approaching Vaprio with 1 brigade, Grenier stopped Ott's advance, who had so far only 4 battalions, 4 squadrons and several Cossack sotnias. It was François Quesnel's brigade. The Allies attacked the French several times, but without success; the French held the excellent terrain for defence, as the village of Vaprio itself was very advantageous for the infantry. The neighborhood was close country and mostly planted with vines, while the highway from Milan had on either side high banks built up with stones collected from the fields, like a natural parapet. The French posted themselves behind it, whereas Grenier was approached by the 2nd brigade under Georges Kister; he had 9 battalions and 8 squadrons assembled and took the offensive. The French now had a strong numerical superiority. Grenier began to dislodge Ott's division from the front, threatening its right flank at the same time. Chasteler rushed to the aid with 2 battalions of Zopf's division and 2 squadrons, but even this support could not stop the French, and one of the approaching battalions (Stentsch) was mauled up by French cavalry. This is where Denisov's Cossacks (all three Cossack regiments under his command) and Austrian hussars charged from the left of the French and halted their advance; joining together, the Cossacks and hussars broke into the ranks of the French infantry, forcing it to retreat towards Pozzo. At this time the French were approaching from Milan by 24th Chasseurs à Cheval Regiment: the Cossacks attacked it, overturned, and pursued as far as Gorgonzola, capturing many prisoners.
Ott and Zopf had broken through. With the arrival of the rest of Zopf's battalions, the Austrian infantry of Ott and Zopf attacked the villages of Pozzo and Vaprio (6 km north from Cassano), which were the flanks of Grenier's division. Suvorov rode from one victorious unit to the next, urging the men on to final efforts. Discovering the 2nd battalion of the Austrian regiment of Esterhazy resting at a halt, he called out:
Bayonets! On with the advance!
Colonel d'Aspre protested that the men had been on the march for fifty hours, and were totally spent, at which Suvorov answered:
Well, I still have my Russians — I know that they will be after the enemy!
After a fierce battle both villages were taken. At the end there were about 11,000 Austrians and Cossacks versus 7,000 French. It cannot be said that the outcome of the combat of Vaprio could have been the only outcome: the timely arrival of 3,000 Sérurier's, 6,000 Victor's (2,000 he could abandon in Cassano d'Adda on the way), would be 16,000 French, led by skilful Moreau, against 11,000 of the enemy. But Moreau, seeing that Victor was not approaching and hearing the cannonade in the rear, from Cassano, orders Grenier to retreat and take a new position between Cassano and Inzago. But it was too late. The pre-bridge fortification in front of Cassano, was under a high pressure. The French 106th demi-brigade, supported by a brigade of Victor's division (which arrived at 4 o'clock in the afternoon; under the command of Argod), held firmly behind the Retorto canal, which covered the front of their position for 5 hours.
Suvorov ordered Melas to take Cassano at all costs. The Austrians placed 30 guns, built a bridge, rushed to assault the fortification and burst into it so quickly that the French had no time to destroy the bridge over the river and remove the guns while retreating to the right bank of the Adda. Argod was killed. It was Reisky regiment that went to the assault. The Austrians crossed the bridge and found themselves in the rear of the French retreating from Vaprio. The direct road to Milan via Gorgonzola was cut off, the French had to hasten their retreat to Melzo, and parts of Victor's division, which had not had time to join Grenier and Laboissière's troops, were ordered to withdraw to Melegnano. Suvorov's assault forced Moreau to a general retreat. After a continuous hard fighting from 6 a.m. to 6 p.m., both Allied columns were so fatigued that they could not pursue and stopped on the battlefield. The Cossacks followed the retreating French. The winners got 19 guns, a colour and over 2,000 POW with very heavy loss of KIA and WIA among the French; the allies lost over 1,000 men. Reporting to Emperor Paul, Suvorov especially "praised the excellent courage of Don Cossacks", calling their Ataman Denisov "brave warrior". Thus by the evening of April 27 the fate of the battle on the Adda River was decided and the way to Milan was opened. At the same time Vukassovich succeeded in bringing down the enemy at Brivio (it was a small French outpost), and at night passed to the right bank of the Adda; the French barely managed to retreat to Lake Como, and Soyez, still occupying Lecco, seeing that the Russian troops were approaching again, rushed into the mountains and barely escaped, having crossed Como in vessels.
Verderio
Sérurier, exactly following Moreau's orders, halted between Verderio and Paderno d'Adda (he was standing with his back to the Adda), carefully entrenched himself, and remained all the day of the 27th and the night of the 28th of April, awaiting further orders, cut off by Ott from the south and Vukassovich from the north; meanwhile on both sides, at Vaprio and Brivio, the cannonade rang out, and a fierce fight was going on. The fight was over. Moreau retreated, the allies slept on the field of battle; Sérurier remained unnoticed. On the early morning of 28 April, an advance detachment of 1 battalion of Austrians under Prince Rohan and Pozdneev Cossack regiment met a cavalry post on the hill behind Imbersago; Cossacks, advancing toward Paderno, overturned this post and unexpectedly saw a whole detachment of French. Vukassovich, considering it encircled, offered to lay down his arms, but, having received a refusal, led an attack. Rohan advance battalion and Cossacks drove the French out of Paderno, and with the rest of the force Vukassovich bypassed Verderio and attacked the enemy from the rear. The French stubbornly defended at Verderio and even attempted to attack the enemy on the flank, but seeing the approach of Rosenberg's main Russian troops (a mere 17,000 coalition forces), Sérurier decided that further resistance would be reckless and surrendered. Vukassovich trapped 3,000 men at Verderio.
Results
Soon after the coalition's victory, Suvorov wrote to a Russian diplomat:
"The Adda is a Rubicon, and we crossed it over the bodies of our enemies."
In the combats at Lecco, Vaprio, Cassano, and Verderio the French brought into the fray between 18,000 and 18,500 men; they suffered 2,500 killed and wounded, plus 5,000 soldiers, 27 cannon, and 3 colours captured. Losses at Verderio were 300 killed and wounded, plus 2,700 captured. The Austro-Russians lost 2,000 killed and wounded (or 2,500). Another authority gives allied losses as 6,000 and French prisoners as 7,000, without listing French killed and wounded. Perhaps the author included the losses at Verderio in his total. Bodart estimated French losses at 11,000. Another source claims 6,200 Allied losses (Austrians: 3,800 killed and wounded and 1,200 prisoners of war, Russians: 1,200). The figure of 3,800 KIA and WIA almost identical with Carl von Clausewitz's data of around 3,700 Austrians killed and wounded. Clausewitz stated that the numbers of French and Austrians killed and wounded were roughly the same. He does not cited Russian losses and assesses 7,000 French prisoners of war.
Moreau retreated, leaving a 2,400-man garrison in Milan's citadel. Grenier's division withdrew to Novara while Victor and Laboissière pulled back to Valenza. Kaim pressed on to capture Turin on 20 June. Milan's citadel capitulated on 24 May. The bottom line of this battle was that the Republic of France-created Cisalpine Republic was now back in the hands of the Habsburg monarchy.
The next battle for the Allied Field Army would be the unsuccessful Battle of Bassignana on 12 May, and then Suvorov's forces would strike back at the First Battle of Marengo (Battle of San Giuliano) just 4 days later.
The next major action was the Battle of the Trebbia on 17–20 June.
