The Inspector General of Artillery, Prince Adalbert of Prussia, wrote in his evaluation on December 30, 1847: “A soldier in body and soul, he also proves himself in his new sphere of activity, to which his chivalrous disposition, his energy, his good general and artillery education, his prudence and dexterity in commanding troops, his lively activity and his great zeal for service make him particularly well suited.”
