On 8 March, Prince Khilkov exchanged shots with Napoleon's guard, but avoided an unequal battle and withdrew.
On the 10th he followed the enemy army along the Vitry road; having reached the village of Sompuy, he harassed the French rearguard with rifle fire for two days before returning to his regiment.
Prince Khilkov's participation in the 1814 war had a conclusion at the battle of La Fere Champenois, at which the Tsarevich chose the Household Dragoons to take the enemy guns.
Khilkov turned his men to face the enemy, fell to hard hand-to-hand fighting and overran the cuirassiers.
On 22 August 1826, the day of Emperor Nikolay Pavlovich's coronation, he was promoted to Lieutenant-General; on 5 July 1827 he was awarded the order of St Vladimir 2nd Class, and on 6 December 1830 the order of St Anna 1st Class with an Imperial crown, having received over the previous ten years, 22 signs of the monarch's favour.
