The U.S. Exploring Expedition (1838-1842) was a success. However, Wilkes was convicted in a court-martial for his harsh command. Later, during the Civil War, he was a ship’s commander. His command was successful, but he was convicted again at a court-martial.

His best friend on the voyage was his dog Sydney, a giant breed called Newfoundland. This breed can swim well, haul fishing nets, and retrieve people or objects that fall into the sea.
