Maré Island

Mare Island is a peninsula in the United States in the city of Vallejo, California, about 23 miles (37 km) northeast of San Francisco. The Napa River forms its eastern side as it enters the Carquinez Strait juncture with the east side of San Pablo Bay. Mare Island is considered a peninsula because no full body of water separates this or several other named "islands" from the mainland. Instead, a series of small sloughs cause seasonal water-flows among the so-called islands. Mare Island is the largest of these at about 3.5 miles (5.6 km) long and a mile wide.

In 1775, Spanish explorer Perez Ayala was the first European to land on what would become Mare Island - he named it Isla de la Plana. This area was part of Rancho Suscol, deeded to General Mariano Guadalupe Vallejo in 1844. It became a waypoint for early settlers. In 1835, whilst traversing the Carquinez Strait, a crude ferry transporting men and livestock capsized in a squall. Among the livestock feared lost in the wreckage was the prized white mare of General Mariano Guadalupe Vallejo, the Mexican Commandante for Northern California. Several days later, General Vallejo's mare was found on the island, having swum ashore. Grateful for the fortunate turn of events, he renamed the island to Isla de la Yegua, Spanish for Mare Island, in her honor. In 1892, development of the Mare Island Golf Club began, making it the oldest golf course west of the Mississippi.

On November 6, 1850, two months after California was admitted to statehood, President Fillmore reserved Mare Island for government use.

On January 15, 1852, Secretary of the Navy William Alexander Graham ordered a Naval Commission to select a site for a Naval Yard on the Pacific Coast. Commodore D. Sloat along with Commodore C. Ringgold, Simon F. Blunt and William P.S. Sanger (former overseer of construction of Drydock Number One, Norfolk Naval Shipyard were appointed to the commission. On July 13, 1852, Sloat recommended the island across the Napa River from the settlement of Vallejo, as it was "free from ocean gales and from floods and freshets." The Navy Department acted favorably on Commodore Sloat's recommendations and Mare Island was purchased for use as a naval shipyard in July 1853 at a cost of $83,410. On September 16, 1854, Mare Island became the first permanent U.S. naval installation on the west coast, with Commodore David Farragut, as Mare Island's first commander.
