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. I got a short note from McPherson that day (written at 2 p.m., when he was within a mile and a half of the railroad, above and near Resaca), and we all felt jubilant. I renewed orders to Thomas and Schofield to be ready for the instant pursuit of what I expected to be a broken and disordered army, forced to retreat by roads to the east of Resaca, which were known to be very rough and impracticable.
That night I received further notice from McPherson that he had found Resaca too strong for a surprise; that in consequence he had fallen back three miles to the month of Snake Creek Gap, and was there fortified. I wrote him the next day the following letters, copies of which are in my letter-book; but his to me were mere notes in pencil, not retained
HEADQUARTERS MILITARY DIVISION OF THE MISSISSIPPI IN THE FIELD, TUNNEL HILL, GEORGIA, May 11, 1864
Major-General McPHERSON, commanding army of the Tennessee, Sugar Valley, Georgia.
General: I received by courier (in the night) yours of 5 and 8.30 P. M. of yesterday.
You now have your twenty-three thousand men, and General Hooker is in close support, so that you can hold all of Jos. Johnston’s army in check should he abandon Dalton. He cannot afford to abandon Dalton, for he has fixed it up on purpose to receive us, and he observes that we are close at hand, waiting for him to quit. He cannot afford a detachment strong enough to fight you, as his army will not admit of it.
Strengthen your position; fight any thing that comes; and threaten the safety of the railroad all the time. But, to tell the truth, I would rather the enemy would stay in Dalton two more days, when he may find in his rear a larger party than he expects in an open field. At all events, we can then choose our own ground, and he will be forced to move out of his works. I do not intend to put a column into Buzzard-Roost Gap at present.
