In the Battle of Kay, Hülsen suffered bloody losses and he himself was later wounded in the subsequent Battle of Kunersdorf. In the Battle of Maxen, he did not arrive in time to support Friedrich August von Finck. On 20 August 1760, he was able to defend himself against a hostile uprising with 12,000 men in the Battle of Strehla, whereupon the King gave him 1500 thalers, and wrote: "I congratulate you [...] [Please extend to ] Officers of your subordinate Corps [...] My most gracious Compliments."
