In 1807, the Horse Guards fought in the battles of Heilsberg and Friedland. On 2 June (N.S. 14 June) at Friedland, the regiment attacked and overturned the French cavalry and then broke into the infantry regiments. The 4th squadron of the regiment under the command of rittmeister Ivan M. Vadbolsky, at the cost of heavy losses, saved the regiment from counterattacks by French cavalry. In the cavalry attack, 16 officers and 116 lower ranks of the regiment were killed.
