At once, Lieutenant Grant stepped forward and saluted. "I will go, Colonel," he said. "You are just the man. If anybody can ride through, you can. But hurry." And Grant did. Crouching low on his mustang like an Indian, he dashed down the bullet-swept streets, made the open, and delivered his message to General Twigg. The Mexican War was marked by the political rivalry of two American Generals, one of whom was destined to win the highest honors in the gift of his country--General Zachary Taylor, old "Rough and Ready," and General Winfield Scott, "Fuss and Feathers." Both were able leaders, though totally unlike in their methods. Taylor cared nothing for personal appearance or etiquette. He worked in close contact with his men. Scott, on the contrary, was fond of display, and issued his orders through his staff officers. Scott was now given supreme command of the Mexican campaign, and summoned all the regular troops for an invasion by way of Vera Cruz--the scene of a later landing, in very recent years. Taylor was left with only the volunteers, but he utilized them at Buena Vista to such good effect that at the next election old "Rough and Ready" became President of the United States--the very thing that his political foes at Washington had tried to prevent, by giving Scott the supreme command. Grant's company, with other regulars to the number of eight thousand men, landed at Vera Cruz, and early in April began its perilous march into the interior. Roads had to be built and bridges constructed, and the army engineers toiled night and day. Among them were two young West Pointers, George B. McClellan and Robert E. Lee. Thus it was that Grant and Lee first came to know each other, in the wilds of Mexico. By the middle of May they had reached Puebla, which they captured easily. But the army needed supplies, and Quartermaster Grant was sent out with an escort of one thousand men to forage the surrounding country. They filled their wagons and returned safely. This jaunt delighted Grant's soul. It was far better than bringing up the rear on a dusty line of march. In one of his letters home he writes: "I have been delighted with the Mexican birds. Their plumage is superlatively splendid. They beat ours in show, but to my mind do not equal them in harmony. I have written this letter with my sword fastened to my side, my pistols within reach, not knowing but that the next moment I may be called into battle." It is an odd coincidence, that at a later day we find another soldier--destined to lead his country's armies to victory in a far mightier conflict--using the soil of Mexico as a training ground. That soldier was John J. Pershing. One other exploit of Grant's in the Mexican campaign must be mentioned, as it was not only daring, but it also revealed his resourcefulness.
