Bragg became aware on June 26 of the significant fighting on his right flank and that the actions on his left were a feint. He ordered Polk to take his corps on a night march toward Murfreesboro through Guy's Gap and attack the Union force at Liberty Gap from the rear, while Hardee pressed them in front. Polk objected to the difficulty of the assignment and Bragg eventually called off the attack as he came to realize the threat from Thomas. Meanwhile, Rosecrans ordered McCook to withdraw from Liberty Gap to the north, skirt around the upper reaches of the Highland Rim, and exploit Thomas's breakout at Hoover's Gap.
