striking out the Twelfth Corps number was stupid, unnecessary, and unjust. If done out of consideration for the Eleventh, it was a mistake; for the men of that corps expressed themselves freely that, their own divisions having been broken up, they would have gladly taken the Twelfth Corps title as well as its honored badge. They knew that corps; they had fought by its side. They knew nothing of the Twentieth. Upon the discontinuance of the Twelfth Corps, General Slocum was assigned to the command of the District of Vicksburg, but resumed the corps command — of the Twentieth Corps--during the Atlanta campaign, General Hooker having been relieved. Slocum afterwards commanded the Army of Georgia while on the March to the Sea, and in the battles of the Carolinas. He was, pre-eminently, one of the ablest generals of the war; he made no mistakes; wherever he was in command, everything went well. His troops had unbounded confidence in his ability, and always went into action with perfect confidence; they felt that with him, there would be no surprise, no rout, no defeat. The Twelfth Corps was small, but was composed of excellent material. Among its regiments were the Second Massachusetts, Seventh Ohio, Fifth Connecticut, One Hundred and Seventh New York, Twenty-eighth Pennsylvania, Third Wisconsin, and others equally famous as crack regiments; all of them with names familiar as household words in the commlunities from which they were recruited.

The Thirteenth and Fourteenth (corps were the first ones organized in the Western armies. They were created on the same date, October 24, 1862, by General Order No. 168, War Department, which ordered that “the troops under the command of Major-General Grant will constitute the Thirteenth Army Corps.” As these troops included the whole Army of the Tennessee, it became necessary to subdivide the corps, which was done December 18, 1862, and four organizations, the Thirteenth, Fifteenth, Sixteenth, and Seventeenth corps were accordingly formed, with General John A. McClernand in command of the Thirteenth. In the meantime, General Sherman, with a portion of the Thirteenth Corps, the right wing. embarked at Memphis on the Yazoo Expedition, during which he made an unsuccessful assault on the outer works of Vicksburg, at Chickasaw Bluffs. Loss, 208 killed, 1,005 wounded, and 563 missing; total, 1,776, out of 33 regiments engaged. The forces consisted of the divisions of Generals A. J. Smith, Morgan L. Smith, George W. Morgan, and Frederick Steele, numbering 30,075 men. The regiments, with a few exceptions, were under fire for the first time. There was some close fighting done; “the flag of the Sixteenth Ohio was shot to tatters, only shreds remaining on the staff; and the flag of the Twenty-second Kentucky was scarcely less torn, and not less dripping with blood.” --[Official Report.] In January, McClernand moved on an expedition against Arkansas Post, talking with him the Thirteenth and Fifteenth corps. He styled his forces, “the Army of the Mississippi,” and designated them as s the First and Second corps of the same. He placed General Morgan in temporary command of his own corps — the Thirteenth; General Sherman was in command of the Fifteenth. The Confederate works at Arkansas Post were carried by storm, the losses in the Thirteenth Corps amounting to 48 killed, 397 wounded, and 18 missing; total, 463, the bulk of which fell on Burbridge's Brigade of A. J. Smith's Division. Only two divisions
