Rivera reached the site of present-day San Diego in May, established a camp in the area that is now Old Town and awaited the arrival of the others. Because of an error by Vizcaíno in determining the latitude of the San Diego Harbor, the ships passed by it and landed too far north before finding their way back. The "San Antonio" arrived on April 11 and the "San Carlos", the first ship to leave La Paz, having met with fierce winds and storms on the journey, arrived on April 29. A third vessel was to follow with supplies, but it was probably lost at sea. The land expedition of Portolá arrived on June 29. After their arduous journeys, most of the men aboard ship were ill, chiefly from scurvy, and many had died. Out of a total of 219 who left Baja California, little more than 100 now survived.
