The capture of Bergamo took place 24 April 1799 during Suvorov's Italian campaign as part of War of the Second Coalition, when 2 Don Cossack regiments of Prince Bagration's vanguard under the command of Colonel Grekov and Ataman Denisov quickly and unexpectedly attacked the town of Bergamo occupied by the French garrison and seized Citadel of Bergamo. The attack proved successful for the Russians. The French army was led by Barthélemy Schérer.
Action development
Before the main forces of Bagration's vanguard crossed the Oglio River, Grekov, with his Cossack regiment and part of Denisov regiment, was sent to pursue the French rearguard retreating from Palazzolo sull'Oglio to Bergamo. He consisted of 150 men and carried 6 guns, as well as his position was on a steep hill. Grekov personally led the soldiers to attack in a heavy battle, Denisov arrived at the end of the skirmish, describing his actions, he notes the heroism shown by Grekov and Cossacks:
I hastened up with my regiment, and saw that just beyond the wood there was a walled town where the last regiment of French was engaged with the Grekov regiment—hence the shooting and the cries. I was at first taken aback by this unexpected encounter, but I ordered my regiment to divide in two, and gallop around the town yelling, so as to alarm the enemy still further. I myself hastened to the town, where I found the Grekov regiment rushing at the enemy like lions and skewering them with their lances as they crowded into the streets. The most useful thing I could do was to join the heroic Grekov, and encourage the Cossacks by crying out: "Keep on, dear comrades, keep on!" It seemed that for every Cossack in pursuit there were one hundred French who were being hunted down, for only one of my regiments was in action. The French did not even think of turning about, but instead fled through the town from one end to the other, and erupted from the far side.
The Cossacks victory this clash and rushed in pursuit and entered the town (fortified and crowded) suddenly and unexpectedly, that's why the French offered no resistance to the Cossacks. When citadel seized, the Cossacks captured 130 prisoners, 19 siege guns, 1 standard, many weapons, and military supplies at Bergamo. Suvorov was very pleased with the successful operation. Despite the rain and mud, he arrived in Bergamo and congratulated Grekov and Denisov on their victory. The capture of the fortress allowed the main troops to reach the Adda River, where the c. 27,000–28,000 of Schérer's army was defeated in the ensuing battles of Lecco and Cassano (26–28 April). This battle cost the French a 6,900–7,500 casualties, incl. 5,000 captured. Allied casualties range from 2,000 to 4,886, incl. c. 1,000 captured. Participants in the operation to capture Bergamo also took part in it.
