First Ship into San Francisco Bay

On August 5, 1775, the Spanish packet San Carlos, under the command of Lieutenant Juan Manuel de Ayala, became the first ship to enter San Francisco Bay. A month and a half was spent in surveying the bay from its southernmost reaches to the northern end of present-day Suisun Bay. The San Carlos departed September 18, 1775.
