JULY 8TH—There is a stout gray-haired old man here from Maryland applying to be made a general. It is Major J. H. Winder, a graduate of West Point, I believe ; and I think he will be successful. He is the son, I believe, of the Gen. Winder whose command in the last war with England unfortunately permitted the City of Washington to fall into the hands of the enemy. I have almost a superstitious faith in lucky generals, and a corresponding prejudice against unlucky ones, and their progeny. But I cannot suppose the President will order this general into the field. He may take the prisoners into his custody—and do other jobs as a sort of head of military police; and this is what I learn he proposes. And the French Prince, Polignac, has been made a colonel; and a great nephew of Kosciusko has been commissioned a lieutenant in the regular army. Well, Washington had his Lafayette—and I like the nativity of these officers better than that of the Northern men, still applying for commissions.
