Priests working to convert CHamorus to Christianity are met with resistance. CHamorus accept some but not all of their teachings. Once Padre San Vitores is killed, soldiers are brought to subdue the uprising. Many are killed. A last battle a Aguijan ends in defeat and the Spanish gain control over the Marianas.
