The favorite of them all was "Daniel Webster," soon called by the members of the general's staff "that devil Dan," because of his speed with which the staff officers had great difficulty in keeping pace. During the battle of the Antietam the great horse carried the commander safely through the day.
"Daniel Webster" was a dark bay about seventeen hands high, pure bred, with good action, never showing signs of fatigue, no matter how hard the test. He was extremely handsome, with more than ordinary horse-sense. He was a fast walker, an important requisite in a commander's charger, but a disagreeable quality for the staff officers whose horses were kept at a slow trot. After McClellan retired to private life, "Dan" became the family horse at Orange, N.J., where he died at the age of twenty-three. McClellan said: "No soldier ever had a better horse than I had in 'Daniel Webster.'"
