 In 1836, the mountain dwelling Kumeyaay with some aid from some former mission neophytes, raided and plundered the rancho.They besieged the ranch house and due to the house being built on an elevation, the men within managed to hold out until it was relieved by a force from San Diego.With his stock and horses stolen and the house burned, Bandini like owners of other ranchos near San Diego had to abandon the isolated rancho, into the 1840s.
