Seydlitz led his squadron at the Battle of Soor on 30 September, scouting the enemy's position before the battle, and then participating in the action. He was also present in the engagement at Katholisch-Hennersdorf on 23 November, which proved convincingly to Frederick the benefit of close support during a cavalry charge. At the successful action on 27 November, Seydlitz led 15 squadrons in an attack on the Austrian rear guard. The Austrians were dispersed and nearly destroyed.
