Texas claimed to own far more territory than Mexico was willing to concede, but the facts might easily have been ascertained had the United States government desired to avoid a war. Unfortunately, it had no such desire, and General Zachary Taylor was soon ordered to occupy the disputed territory with about 3,000 men. This force, of which Grant's regiment formed a part, was called the Army of Observation, but it might better have been called the Army of Provocation, for it was obviously intended to provoke an attack on the part of Mexico and to give the United States an excuse for declaring war and settling the boundary question to suit itself. Probably, there were not many in the army who thought much about the rights or the wrongs of the impending war. There had been no fighting in the United States for more than thirty years, and most of the officers were more interested in seeing real service in the field than they were in discussing the justice or injustice of the cause. Grant was as anxious for glory as any of his comrades, but he cherished no illusions as to the merits of the dispute in which his country was involved. With the clear vision of the silent man who reads and thinks for himself, he saw through the thinly disguised pretenses of the politicians and, recognizing that force was being used against a weaker nation in order to add more slave states to the Union, he formed a very positive opinion that the war was unjustifiable. But though he was forced to this disagreeable conclusion, the young Lieutenant was not the sort of man to criticize his country once she was attacked, or to shirk his duty as a soldier because he did not agree with his superiors on questions of national policy. He thought and said what he liked in private, but he kept his mouth closed in public, feeling that his duties as an officer were quite sufficient without assuming responsibilities which belonged to the authorities in Washington. War was inevitable almost from the moment that Texas was annexed, but with full knowledge of this fact neither the President nor Congress made any effective preparations for meeting the impending crisis, and when hostilities actually began, General Taylor was directed to advance under conditions which virtually required him to fight his way to safety. Indeed, he was practically cut off from all hope of reënforcement as soon as the first shot was fired, for his orders obliged him to move into the interior of the country, and had his opponents been properly commanded, they could have overwhelmed him and annihilated his whole force. The very audacity of the little American army, however, seemed to paralyze the Mexicans who practically made no resistance until Taylor reached a place called Palo Alto, which in Spanish means "Tall Trees."
