On the morning of March 19, Serra celebrated Mass and preached a sermon at the forlorn mission on Presidio Hill. No ship appeared in the bay that morning. But around 3 o'clock in the afternoon, the sails of a ship—the "San Antonio"—came into view on the horizon. It sailed past San Diego Bay, destined for Monterey. When it got to the Santa Barbara Channel, its sailors made landfall to fetch fresh water. There they learned from Indians that the Portolá expedition had returned south. So the "San Antonio" also turned south, anchoring in San Diego Bay on March 23.
