It is as well known to others present as to me that, during that gloomy, eventful Sunday which succeeded the last battle on Saturday, the 30th of August, the President and Mr. Stanton were overrun and overcome with statements that, unless McClellan was restored to command "the army would not fight." These statements came from men who did not mean it should fight, who could not in the exigency of the moment be displaced. The President was able afterward to relieve McClellan and court-martial Porter. Had he lived, he would have seen justice to General Pope awarded also. It remains for me, while I live, to do my portion of that duty. There is one other point to which I wish to allude. During this very trial--during the very pendency of the trial--Fitz-John Porter said, in the presence of my informant, who is a man whom most of you know, and who is to-day in the employment of Congress, and whose word I would take as soon as I would most men's--though I told him I would not use his name, but I will give his sworn testimony, taken down within two minutes after the utterance was made--Fitz-John Porter said in his presence: "I was not true to Pope, and there is no use in denying it." Mr. President, what was "not true to Pope"? If he was not true to Pope, whom was he true to? Being true to Pope was being true to the country; "not true to Pope" was being a traitor to the country. Sir, "not true to Pope" meant the terrible fight of the 30th of August, with all the blood and all the horrors of that bitter day; "not true to Pope" meant the battle of Antietam, with its thousands of slain and its other thousands maimed; "not true to Pope" meant the first battle of Fredericksburg, with its 20,000 slain and maimed; "not true to Pope" covered the battles of the Wilderness and Cold Harbor, and all the dreadful battles that followed. Had Fitz-John Porter been true to his government, Jackson would have been destroyed on the 29th of August, and on the 30th the rebels could scarcely have offered any resistance to our victorious army. "Not true to Pope" meant 300,000 slain and 2,000,000,000 of additional dollars expended. Sir, I wish to put this on the record for all time, that it may remain. Let Fitz-John Porter thank God that he yet lives, and that he was not living at that time under a military government. I told General Pope, in the first interview I had with him, that I had but one fault to find in the whole conduct of the campaign. He asked, "What is that?" Said I, "That you ever allowed Fitz-John Porter to leave the battle-field alive!"
