During World War II, Fort Mason became the headquarters of the "San Francisco Port of Embarkation", controlling a network of shipping facilities that spread across the Bay Area. Over the years of the war, 1,647,174 passengers and 23,589,472 measured tons moved from the port into the Pacific. This total represents two-thirds of all troops sent into the Pacific and more than one-half of all Army cargo moved through West Coast ports. The highest passenger count was logged in August 1945 when 93,986 outbound passengers were loaded.
