He participated in the campaign of 1805 year and after it in the war against Sweden .
In the war of 1812 year he was a General and commanded a brigade in the 3-rd Infantry Division. He distinguished himself in the battles at Vitebsk and Smolensk in the detachment of his brother Pavel Alexeevich.
In the Borodino battle he was the commander of the Revel regiment and was among the defenders of the Semenovsky (Bagration's) fleshes (fortifications).

Here you can see the portrait of this young brave general. Fedor Glinka, a participant of the war of 1812 year, wrote about him:
There is a soul in his features, especially in his eyes, his lips. You can imagine that a man who has them has heart, imagination and can think and dream even in a military uniform..."
