John Stilwell Jenkins, History of the War between the United States and Mexico (1849)
“ The republic of Mexico, for such she has claimed to be, amid all the phases and changes in her political condition, has never possessed a firm or stable government since 1821, when she ceased to be one of the dependencies of the Spanish crown, except during the first presidency under the federal constitution. Her prolonged struggle for independence was not viewed with indifference in the United States. The government of the latter was the first to recognize her separate existence, and her battle fields were crimsoned with the blood of many an American citizen. ”
