peril, for he came at a time when the ammunition wagons were delivering cartridges, and the road at the end of the bridge where they were was in the range of the enemy's constant and accurate fire. It is proper to mention this because it has been said that he did not cross the stream. The criticisms made by McClellan as to the time occupied in these changes and movements will not seem forcible if one will compare them with any similar movements on the field; such as Mansfield's to support Hooker, or Sumner's or Franklin's to reach the scene of action. About this, however, there is fair room for difference of opinion: what I personally know is that it would have been folly to advance again before Willcox had relieved Sturgis, and that as soon as the fresh troops reported and could be put in line, the order to advance was given. McClellan is in accord with all other witnesses in declaring that when the movement began, the conduct of the troops was gallant beyond criticism. Willcox's division formed the right, Christ's brigade being north, and Welsh's brigade south of the road leading from the bridge to Sharpsburg. Crook's brigade of the Kanawha division supported Willcox. Rodman's division formed on the left, Harland's brigade having the position on the flank, and Fairchild's uniting with Willcox at the centre. Scammon's brigade was the reserve for Rodman at the extreme left. [Footnote: Official Records, vol. xix. pt. i. pp. 425, 430.] Sturgis's division remained and held the crest of the hill above the bridge. About half of the batteries of the divisions accompanied the movement, the rest being in position on the hill-tops east of the Antietam. The advance necessarily followed the high ground toward Sharpsburg, and as the enemy made strongest resistance toward our right, the movement curved in that direction, the six brigades of Jones's Confederate division being deployed diagonally across our front, holding the stone fences and crests of the cross-ridges and aided by abundant artillery, in which arm the enemy was particularly strong.
