Battle Of San Pasqual
The Battle of San Pasqual (also spelled San Pascual) was a military encounter that occurred during the Mexican-American War in what is now the San Pasqual Valley community of the city of San Diego, California.
On December 6 and December 7, 1846, Stephen W. Kearny's US Army column defeated the Californios, and their Presidial Lancers, led by General Don Andrés Pico.
Meanwhile, General Stephen W. Kearny, with a squadron of 139 dragoons that he had led on a grueling march across New Mexico, Arizona, and the Sonoran desert, finally reached California on December 6, 1846, and fought in a small battle with Californio lancers at the Battle of San Pasqual near San Diego, California, where 22 of Kearny's troops were killed.
