12th.—Quiet in camp all day. It seems hard that we must lose this beautiful weather, when winter is so near at hand; but I suppose it is necessary to allow the new Commander-in-Chief to perfect his plans. General Fitz-John Porter re-arrested to-day, and taken to Washington, on charge of disobedience of General Pope’s orders, at the battle of Bull Run, on the 29th of August. That the defeat of Pope’s army there, the slaughter of thousands of our true and loyal men, the escape of Lee’s and Jackson’s commands from capture or destruction, was the result of treason, there is not a shadow of doubt. If Porter is proven to be the traitor—hang him, hang him; for God’s sake hang him; and if a traitor at the instigation of a higher in command, hang him too. We have had enough of this thing of staking the lives of our men, by whole brigades, on political chess games. Hang a few of the traitors to save the sacrifice of true and honest men.
