AUGUST 29TH. —We have intelligence from the North that immense preparations are being made for our destruction; and some of our people begin to say, that inasmuch as we did not follow up the victory at Manassas, it was worse than a barren one, having only exasperated the enemy, and stimulated the Abolitionists to renewed efforts. I suppose these critics would have us forbear to injure the invader, for fear of maddening him. They are making this war; we must make it terrible. With them war is a new thing, and they will not cease from it till the novelty wears off, and all their fighting men are sated with blood and bullets. It must run its course, like the measles. We must both bleed them and deplete their pockets.
