In 1813, Chechensky took part in the battles near the cities of Bautzen and Lucin. The new commander of the army, Barclay de Tolly, who replaced the deceased Mikhail Kutuzov in the Silesian town of Bunzlau, confers on A. Chechenskiy the rank of colonel for bravery and courage. For successful actions, he was transferred as a commander to the Life Guards Hussar Regiment. This regiment captures Osnabrück without loss, and then distinguishes itself in the battles for the cities of Delitzsch and Tolkh. Alexander Chechensky with his regiment participates in the historical battle of the nations near Leipzig.
