From Tunnel Hill I could look into the gorge by which the railroad passed through a straight and well-defined range of mountains, presenting sharp palisade faces, and known as "Rocky Face." The gorge itself was called the "Buzzard Roost." We could plainly see the enemy in this gorge and behind it, and Mill Creek which formed the gorge, flowing toward Dalton, had been dammed up, making a sort of irregular lake, filling the road, thereby obstructing it, and the enemy's batteries crowned the cliffs on either side.

The position was very strong, and I knew that such a general as was my antagonist (Jos.
Johnston), who had been there six months, had fortified it to the maximum.

Therefore I had no intention to attack the position seriously in front, but depended on McPherson to capture and hold the railroad to its rear, which would force Johnston to detach largely against him, or rather, as I expected, to evacuate his position at Dalton altogether.

My orders to Generals Thomas and Schofield were merely to press strongly at all points in front, ready to rush in on the first appearance of "let go," and, if possible, to catch our enemy in the confusion of retreat.
All the movements of the 7th and 8th were made exactly as ordered, and the enemy seemed quiescent, acting purely on the defensive.
I had constant communication with all parts of the army, and on the 9th McPherson's head of column entered and passed through Snake Creek, perfectly undefended, and accomplished a complete surprise to the enemy.

At its farther debouche he met a cavalry brigade, easily driven, which retreated hastily north toward Dalton, and doubtless carried to Johnston the first serious intimation that a heavy force of infantry and artillery was to his rear and within a few miles of his railroad.
