The Battle of Grodno was one of the first battles that took place on June 27–28 at the initial stage of the Patriotic War of 1812 between the vanguard of the right wing of Napoleon's Grand Army and the rearguard of the Russian 2nd Western Army.
On June 20, 1812, the regiments of the Cossack Corps of Ataman Platov (14 regiments) arrived in the vicinity of Grodno to guard the borders. Four days later, 130 kilometers north of Grodno, near the city of Kovno, Emperor Napoleon Bonaparte began to ferry troops across the Neman River to attack Kovno.[1]
On June 24, from the city of Lomzha, the King of Westphalia, Jérôme Bonaparte, advances the right wing of the Great Army under the command of Brigadier General Alliks de Vo through Avgustov to Grodno.[2]
On the evening of June 26, Platov's Cossack Corps, which was originally the vanguard of the 2nd Western Army, was given orders by Aleksandr I to act on the enemy's flank and rear.[3] Therefore, the regiments of his corps began to be withdrawn from the border from border settlements to concentrate through Lida near Sventsyany. Ataman Platov begins the evacuation of part of the garrison, officials with their families and city supplies (more than 1000 convoys) through Novogrudok in the direction of Minsk.[4] To cover the evacuation, Platov deployed Cossack regiments on the approaches to Grodno.
On June 27, on the Lososyanka River, four kilometers west of Grodno, several Cossack regiments entered into battle with three regiments of the Polish Division of General Dąbrowski, moving towards Grodno. At the river, the Kazaks started a firefight and delayed the enemy's advance.
On June 28, the Cossack positions were withdrawn to the bridge near Grodno, in the Neman Suburb. In the morning, together with the reinforcements of General Kaminskiy, under the overall command of General of Artillery Alliks de Vo, the enemy attacked the suburb in the direction of the bridge. The first to attack the suburbs were the lancers, who started a battle with the Cossack Hundred. The infantry followed towards the bridge. The city garrison helped the Cossack regiments hold the bridge.
Platov took up defensive positions on the heights of the right bank of the Neman and from there fired on the advancing units with 12 guns from the Don Artillery Company.[1] The fierce exchange of fire with the enemy continued until the evening.[5]
Seeing no way to hold back the increasing onslaught of the enemy with only the forces of the Kazaks, and not having regular infantry, in the evening Platov burned the bridge over the Neman and retreated from Grodno through Shchuchin in the direction of Lida.[6]
