On June 28, sergeant José Ortega, who had ridden ahead to meet the Rivera party in San Diego, returned with fresh animals and letters to Serra from friars Juan Crespí and Fernando Parrón. Serra learned that two Spanish galleons dispatched from Baja to supply the new missions had arrived at San Diego Bay. One of the ships, the "San Carlos", had sailed almost four months from La Paz, bypassing its destination by almost 200 miles before doubling back south to reach San Diego Bay. By the time it dropped anchor on April 29, scurvy had so devastated its crew that they lacked the strength to lower a boat. Men on shore from the "San Antonio", which had arrived three weeks earlier, had to board the "San Carlos" to help its surviving crew ashore.
