the morning of the 13th, he found that Polk had not advanced against the enemy, and that “the latter's forces had formed a junction and recrossed the Chickamauga.” His language clearly conveys the impression that, but for Polk's remissness, the intended attack on part of Crittenden's corps would have been made. It appears, however, from Polk's report to army headquarters, dated September 12, 8 P.M., that Bragg did him injustice. Polk reached the ground in good season, but the information he collected after his arrival led him to believe that not one of Crittenden's divisions, but all three, were in front of him and advancing “with steady step upon my position, and will no doubt attack early in the morning”; hence he considered it his duty to ask “most respectfully and urgently” for reinforcements. Polk added: “My troops I cannot get into position in time to attack, myself, at so early an hour as day-dawn. If I find he is not going to attack me, I will attack him without delay.”
The truth was, however, that while Bragg's information, on which he based his order to Polk to attack the one division of Crittenden's corps, was reliable, Polk's assumption that three divisions were before him was also well founded. General Harker's brigade of Wood's division, forming the rear of the corps, had been ordered by Crittenden early on the 11th to make a reconnoissance from Rossville to Lee and Gordon's Mills. Early in the afternoon Wood was ordered to move at once to the support of Harker with his other brigade (his third had been left at Chattanooga), which he did. It was the movement of these two brigades that was reported to Bragg. But when General Rosecrans perceived that his salvation lay in the immediate concentration of his army, he sent, simultaneously with his orders to McCook to join Thomas, directions to Crittenden to move also towards the latter by marching his whole corps “by the most available route,” and as quickly as possible, to the road from Rossville to Lafayette that Wood had followed, and to close up with the latter.
