"Measured by its results, San Jacinto was one of the decisive battles of the world. The freedom of Texas from Mexico won here led to annexation and to the Mexican War, resulting in the acquisition by the United States of the States of Texas, New Mexico, Arizona, Nevada, California, Utah, and parts of Colorado, Wyoming, Kansas and Oklahoma. Almost one-third of the present area of the American nation, nearly a million square miles of territory, changed sovereignty."
