GENERAL;The general commanding directs me to inform you that General McCook has been ordered to hold this gap to-morrow, crossing the Dry Valley road, his right resting near this place, his left connecting with General Thomas' right. The general places your corps in reserve to-morrow, and directs you to post it on the eastern slope of Missionary Ridge to support McCook or Thomas. Leave the grand guards from your command out, with instructions to hold their ground until driven in, and then to return slowly, contesting the ground stubbornly.
