Lieutenant Colonel Henry S. Burton marches out…
March 1848 CE
His forces rescue captured Americans, capture Pineda, and, on March 31, defeat and disperse remaining Mexican forces at the Skirmish of Todos Santos.
When the American garrisons are evacuated to Monterey following the treaty ratification, many Mexicans go with them: those who had supported the American cause and had thought Lower California would also be annexed along with Upper California.
