Charles Wilkes may have accomplished something great with his voyage of circumnavigation, the first major scientific naval expedition sponsored by the United States, but he was no shining hero. By all accounts, he was quite a flawed character for all his brilliance, vain and self-centered, stern to a fault, and sometimes amazingly cruel. In typical Silverberg fashion, we get a balanced portrait of the man -- when Wilkes results to violence to punish South Seas islanders, the incident is placed in its time and place. His actions by today's standards would be considered absolutely inconscionable, and he would be on trial for crimes against humanity. In his own time, he was thought to have overreacted, and many of the men in the expedition lost respect for him.
The first chapter is concerned primarily with the lengthy political battles that went on before the journey could even begin, an intriguing portrait of the US government of former days. Parties and personalities clashed, administrations changed, and the result was a poorly-planned voyage with ill-equipped ships not at all suited to the task they were given. The command of the expedition was offered to a variety of Captains during the years leading up to departure, all of whom dropped out, leaving only a lieutenant to command the flotilla (a fact that caused much dissent during the expedition). Great credit must be given to Wilkes and his men for merely surviving, let alone accomplish anything worth remembering after all these years.
Another interesting fact about the Wilkes expedition is that when the survivors returned, the man who had led them was greeted not as a hero, but with a court-martial on a variety of charges, from frivolous nonsense to actual incidents.
I was struck by the similarities between The real-life Wilkes expedition and the fictional expedition of Trajan Draco in "Getting to Know the Dragon" -- once again, Silverberg does not let his extensive knowledge of history go to waste, even when writing about times far removed from our own world.
