This aggressive decision making was typical of Wilkes' command style. On one hand, he was recognized as "a distinguished explorer, author, and naval officer". On the other, he "had a reputation as a stubborn, overzealous, impulsive, and sometimes insubordinate officer". Treasury officer George Harrington had warned Seward about Wilkes: "He will give us trouble. He has a superabundance of self-esteem and a deficiency of judgment. When he commanded his great exploring mission he court-martialed nearly all his officers; he alone was right, everybody else was wrong."
