At twelve o’clock at night, when all was quiet, I began to give orders for the next day, and sent a dispatch to Willcox to encourage Burnside.  Sherman was directed to attack at daylight.  Hooker was ordered to move at the same hour, and endeavor to intercept the enemy’s retreat if he still remained; if he had gone, then to move directly to Rossville and operate against the left and rear of the force on Missionary Ridge.  Thomas was not to move until Hooker had reached Missionary Ridge.  As I was with him on Orchard Knob, he would not move without further orders from me.

The morning of the 25th opened clear and bright, and the whole field was in full view from the top of Orchard Knob.  It remained so all day.  Bragg’s headquarters were in full view, and officers—­presumably staff officers—­could be seen coming and going constantly.

The point of ground which Sherman had carried on the 24th was almost disconnected from the main ridge occupied by the enemy.  A low pass, over which there is a wagon road crossing the hill, and near which there is a railroad tunnel, intervenes between the two hills.  The problem now was to get to the main ridge.  The enemy was fortified on the point; and back farther, where the ground was still higher, was a second fortification commanding the first.  Sherman was out as soon as it was light enough to see, and by sunrise his command was in motion.  Three brigades held the hill already gained.  Morgan L. Smith moved along the east base of Missionary Ridge; Loomis along the west base, supported by two brigades of John E. Smith’s division; and Corse with his brigade was between the two, moving directly towards the hill to be captured.  The ridge is steep and heavily wooded on the east side, where M. L. Smith’s troops were advancing, but cleared and with a more gentle slope on the west side.  The troops advanced rapidly and carried the extreme end of the rebel works.  Morgan L. Smith advanced to a point which cut the enemy off from the railroad bridge and the means of bringing up supplies by rail from Chickamauga Station, where the main depot was located.  The enemy made brave and strenuous efforts to drive our troops from the position we had gained, but without success.  The contest lasted for two hours.  Corse, a brave and efficient commander, was badly wounded in this assault.  Sherman now threatened both Bragg’s flank and his stores, and made it necessary for him to weaken other points of his line to strengthen his right.  From the position I occupied I could see column after column of Bragg’s forces moving against Sherman.  Every Confederate gun that could be brought to bear upon the Union forces was concentrated upon him.  J. E. Smith, with two brigades, charged up the west side of the ridge to the support of Corse’s command, over open ground and in the face of a heavy fire of both artillery and musketry, and reached the very parapet of the enemy.  He lay here for a time, but the enemy coming with a heavy force upon his right flank, he was compelled to fall back, followed by the foe.  A few hundred yards brought Smith’s troops into a wood, where they were speedily reformed, when they charged and drove the attacking party back to his intrenchments.
