On June 20 when the procurement parties failed to return as expected, Lieutenant Ford sent Sergeant Gibson with four men to "Rancho Sotoyome". Gibson obtained the powder and on the way back fought with several Californians and captured one of them. From the prisoner they learned that Cowie and Fowler had died. There are Californio and "Oso" versions of what had happened. Ford also learned that William Todd and his companion had been captured by the Californio irregulars led by Juan Padilla and José Ramón Carrillo.
