Ulysses S. Grant on Mexican–American War

“The Southern rebellion was largely the outgrowth of the Mexican war. Nations, like individuals, are punished for their transgressions. We got our punishment in the most sanguinary and expensive war of modern times.”

“Generally, the officers of the army were indifferent whether the annexation was consummated or not; but not so all of them. For myself, I was bitterly opposed to the measure, and to this day, regard the war, which resulted, as one of the most unjust ever waged by a stronger against a weaker nation. It was an instance of a republic following the bad example of European monarchies, in not considering justice in their desire to acquire additional territory.”

“The Mexicans were badly commanded, and there was very little hard fighting during that war, at least nothing to be compared with what was seen afterward in our own. Our soldiers had only to show the bayonet at the Mexicans and they would run. As to the bowie-knife, I do not think one was used during the war. It was a pity to see good troops used as the Mexican soldiers were in those campaigns. I do not think a more incompetent set of officers ever existed than those who commanded the Mexicans. With an able general the Mexicans would make a good fight, for they are a courageous people. But I do not suppose any war was ever fought with reference to which so many romances were invented as the war in Mexico.”

“When I was in London, talking with Lord Beaconsfield, he spoke of Mexico. He said he wished to heaven we had taken the country, that England would not like anything better than to see the United States annex it. I suppose that will be the future of the country. Now that slavery is out of the way there could be no better future for Mexico than absorption in the United States. But it would have to come, as San Domingo tried to come, by the free will of the people. I would not fire a gun to annex territory. I consider it too great a privilege to belong to the United States for us to go around gunning for new territories. Then the question of annexation means the question of suffrage, and that becomes more and more serious every day with us. That is one of the grave problems of our future.”

“With a soldier the flag is paramount. I know the struggle with my conscience during the Mexican War. I have never altogether forgiven myself for going into that. I had very strong opinions on the subject. I do not think there was ever a more wicked war than that waged by the United States on Mexico. I thought so at the time, when I was a youngster, only I had not moral courage enough to resign. I had taken an oath to serve eight years, unless sooner discharged, and I considered my supreme duty was to my flag. I had a horror of the Mexican War, and I have always believed that it was on our part most unjust. The wickedness was not in the way our soldiers conducted it, but in the conduct of our government in declaring war. The troops behaved well in Mexico, and the government acted handsomely about the peace. We had no claim on Mexico. Texas had no claim beyond the Nueces River, and yet we pushed on to the Rio Grande and crossed it. I am always ashamed of my country when I think of that invasion. Once in Mexico, however, and the people, those who had property, were our friends. We could have held Mexico, and made it a permanent section of the Union with the consent of all classes whose consent was worth having. Overtures were made to Scott and Worth to remain in the country with their armies.”
