The man for whom the city of Stockton is named, Commodore Robert F. Stockton, almost blew up a president of the United States. The 1844 explosion aboard his ship killed the Secretary of State, Secretary of the Navy and others.
And the shipboard accident had huge ramification to American politics and history. It’s mind-boggling, really. A historian has it in the Huffington Post here.
What he omits is that Stockton was so shamed by the incident that he sought to regain his honor by plunging into battle in the war against Mexico. He sailed to California, trained his sailors to fight on land and helped Fremont win land battles. While winning California for the U.S., he met and rescued Capt. Charles Weber, who named the city for him.
