We hear that the Army of the East has won a decisive victory in Pennsylvania. This is grand! It will show the rebels that it will not do to put their feet on free soil. Now if Grant succeeds in taking Vicksburg, and Rosecrans drives Bragg beyond the Tennessee, the country will have reason to rejoice with exceeding great joy.

6. An old lady, whose home is on the side of the mountain, called on me to-day and said she had not had a cup of coffee since the war commenced. She was evidently very poor; and, although we had no coffee to spare, I gave her enough to remind her again of the taste.

Our soldiers have been making a clean sweep of the hogs, sheep, and poultry on the route. For the rich rebels I have no sympathy, but the poor we must pity. The war cuts off from them entirely the food which, in the best of times, they acquire with great labor and difficulty. The forage for the army horses and mules, and we have an immense number, consists almost wholly of wheat in the sheaf—wheat that has been selling for ten dollars per bushel in Confederate money. I have seen hundreds of acres of wheat in the sheaf disappear in an hour. Rails have been burned without stint, and numberless fields of growing corn left unprotected. However much suffering this destruction of property may entail on the people of this section, I am inclined to think the effect will be good. It will bring them to a realizing sense of the loss sustained when they threw aside the protecting shield of the old Constitution, and the security which they enjoyed in the Union.

The season's crop of wheat, corn, oats, and hogs would have been of the utmost value to the Confederate army; when destroyed, there will be nothing in middle Tennessee to tempt it back.

7. Hundreds, perhaps thousands, of Tennesseeans have deserted from the Southern army and are now wandering about in the mountains, endeavoring to get to their homes. They are mostly conscripted men. My command has gathered up hundreds, and the mountains and coves in this vicinity are said to be full of them.

It rains incessantly. We moved to Decherd and encamped on a ridge, but are now knee-deep in mud and surrounded by water.

This morning a hundred guns echoed among the mountain gorges over the glad intelligence from the East and South: Meade has won a famous victory, and Grant has taken Vicksburg.

Stragglers and deserters from Bragg's army continue to come in. It is doubtless unfortunate for the country that rain and bad roads prevented our following up Bragg closely and forcing him to fight in the present demoralized condition of his army. We would have been certain of a decisive victory.

9. Dined with General Negley. Colonels Stoughton and Surwell, brigade commanders, were present. The dinner was excellent; soups, punch, wine, blackberries were on the table; and, to men who for a fortnight had been feeding on hard crackers and salt pork, seemed delicious. The General got his face poisoned while riding through the woods on the 2d instant, and he now looks like an old bruiser.

McCook, whose corps lies near Winchester, called while we were at Negley's; he looks, if possible, more like a blockhead than ever, and it is astonishing to me that he should be permitted to retain command of a corps for a single hour. He brought us cheering information, however. The intelligence received from the East and South a few days ago has been confirmed, and the success of our armies even greater than first reports led us to believe.
