Those were days of great commotion in the Congress of the United States. The whole nation, South as well as North, was divided in opinion as to the righteousness and expediency of the war with Mexico. There were two great parties, both of which have long since passed away, for the question of the annexation of Texas is no longer before the people, and all this was more than half a century ago. One of the parties called itself "Whig," but its enemies described its members as "Coons," in the habit of roosting up a tree out of reach. The other party called itself "Democratic," while its opponents lampooned its members as "Loco-focos," comparing them to the blue-headed sulphur matches of that name, which were largely manufactured and did not burn very well. Party feeling ran high, and the debates in Congress were red-hot. The Democratic President, James K. Polk, was a man of far greater ability and statesmanship than his party enemies were willing to give him credit for, and he was supported by a brilliant array of politicians. On the other hand, the Whig party contained a number of our most distinguished statesmen, and, curiously enough, most of the generals of the army, including Winfield Scott and Zachary Taylor, were well-known Whigs. It was not altogether unnatural, therefore, that the Democratic party in power should wish to put the command of any army preparing for the invasion of Mexico into the hands of officers who were in favor of the war which they were to carry on. Questions like this, and some others relating to the unprepared condition of the American army for so tremendous an undertaking, were responsible for the fact that there was a long delay in all military operations, even after the hard and successful fighting done by General Taylor's forces at the Rio Grande. American cruisers were tacking to and fro over the waters of the Gulf of Mexico and the Caribbean Sea, without any especial errand of which their commanders were aware. Regiments of eager volunteers were forming in several of the States, and were trying hard to discover officers who knew how to drill and handle them. The politicians were everywhere calling each other harder and harder names. Not one soul in all the United States, however, knew anything of a party of mounted men, a carriage, and a spring-wagon, which quietly made its way out of the city of Vera Cruz, not long after sunset, one sultry and lazy evening. At the head of this cavalcade rode two men, who sat upon their spirited horses as if they were at home in the saddle. At their right, however, was a young fellow on a black pony who was entirely satisfied with the fact that the beast under him did not seem to have any spirit at all. He was at that moment steadying his feet in the stirrups, and remarking to himself:
