A military Politician.
--Among the latest arrivals of Yankee officers is Daniel Ullman, formerly the great gun of the Know Nothings of New York. He was operating on the line of the Rappahannock as Colonel of the 78th regiment New York volunteers, when, on the 28th of August, he had the misfortune to fall into the hands of our troops. Ullman's personal appearance is insignificant; as a prisoner he has a desponding and downcast look. He will be sent home with his brother officers.
