Armistice Oak: Where California's Mexican War Ended

Near this spot on January eighth, eighteen forty-seven, a brief but consequential surrender took place beneath a large oak tree. Francisco Sanchez, leading a band of Californio resisters, gave up himself, several American prisoners, and a cache of arms to American forces. The event closed what is sometimes called the Battle of Santa Clara, or the Battle of the Mustard Stalks, named for the fields of dried wild mustard through which the fighting moved on January second.

It was one of the last armed clashes of the Mexican-American War in California. Sanchez and his men had pushed back briefly against the American occupation, but with the formal surrender came the effective end of organized Californio resistance in the Bay Area. A marker here keeps the memory of the oak where the armistice was signed from disappearing entirely beneath the rapid suburban growth of Silicon Valley.
