Timeline of the Portolá expedition
Three
Gálvez placed Gaspar de Portolá, recently appointed governor of Las Californias, in overall command of the expedition. Second in command was Captain Fernando Rivera y Moncada, commander of the Presidio at Loreto. Serra headed the Franciscan missionary contingent. Three ships were also assigned: two to follow the land march up the coast and keep the expedition supplied from the naval depot at La Paz (on the Baja peninsula), and another ship to connect La Paz with the mainland at San Blas.
