in line of battle with three brigades in front and two in reserve by noon, and then advanced and collided within a few minutes with the Federal line, which was driving Liddell's brigades. Cheatham not only checked the Federal advance, but forced it back about three-quarters of a mile, when he encountered fresh hostile columns which made him yield in turn. Learning this, General Bragg ordered Stewart's division of Buckner's corps to make an attack for his relief. Stewart formed his line promptly, and reached the front in time for the rescue of Wright's brigade, forming Cheatham's left, which was falling back in disorder with the loss of its battery. Stewart became at once hotly engaged. As he gained no ground for some time, while losing heavily, Bragg ordered Hood's corps into action on the left of Stewart. Its strongest division, under Bushrod Johnson, entered the fight shortly before 3 P.M. After it had been engaged for some time without decided result, Robertson's brigade of the division Hood had brought with him from Virginia, and Trigg's brigade of Preston's division of Buckner's corps, were sent to its assistance.
In this wise it happened that, in the latter part of the afternoon, no less than seven Federal divisions, less two detached brigades, and five divisions and two brigades of the enemy, had been drawn into the vortex of the battle. Hence there cannot have been much difference between the numbers of combatants on each side. The action shifted during the day from right to left. It was not continuous, but like the rise and fall of the tide. As the several bodies successively came into the fray, it rose to fierceness at the points of collision, surged and roared for a time as the assailing columns advanced, and subsided into more or less protracted lulls as they fell away from each other. It was offensive at first on our part, but became more and more defensive in the course of the day. Foiled in their early attempts to break the left of our line, the rebels directed their onsets from noon against our centre. Brannan, Baird,
