The country will not fail to note---is now noting---that the present hesitation to move upon an intrenched enemy, is but the story of Manassas repeated. I beg to assure you that I have never written you, or spoken to you, in greater kindness of feeling than now, nor with a fuller purpose to sustain you, so far as in my most anxious judgment, I consistently can. But you must act.
