New Almaden
New Almaden, Santa Clara County · California
Erected by New Almaden Historical Society, 1954
The society's 1954 bronze credits a favorable ruling on the mine's title with saving California and Nevada for the Union, and the record runs the other way. In March 1863 the Supreme Court threw out Andrés Castillero's claim, and that year Lincoln signed an order to seize the mine for investors close to his administration. Armed miners met the federal agent at the gate. Wary of losing California mid-war, Washington revoked the order, and Barron, Forbes & Co. sold to those same investors for $1.75 million. No state plaque stands in town.
