Lieutenant T.B. Mackall, aide-de-camp to General Mackall, chief of staff, kept a journal of the operations, during these days, of the Army of Tennessee. May fifteenth, 1864, he writes:— “... 7 A.M. General Johnston has been on hill where Selden’s battery is posted since firing began; is just going to ride to the right, leaving General Mackall here. Skirmishing and artillery still going on. 10 A.M. General Johnston returned to Selden’s battery an hour ago. Answer sent to cipher of the President received yesterday: ‘_Sherman cannot reinforce Grant without my knowledge, and will not as we are skirmishing along our entire line. We are in presence of whole force of enemy assembled from North Alabama and Tennessee._’ Ferguson’s brigade of cavalry, also Brigadier-General Jackson have reached Rome. Wheeler has just gone to upper pontoon bridge, which will not be ready for crossing for fifteen minutes. It is in long range of the six-gun battery put up last night on the hill which they captured. 11 A.M. Very heavy musketry and artillery firing going on, apparently on Hindman’s line. Just before it became so rapid General Johnston rode up the Dalton road, apparently on account of some news brought by Hampton from Hardee. About 11.15 battery on our extreme right opened. Firing slackened on Hindman’s front. Battery on hill on our left enfilades our trenches; riflemen annoying to our gunners. 12 M. General Johnston has come back to Selden’s battery. The firing on extreme right three quarters of an hour ago caused by enemy’s crossing Connesauga in rear of Hood, capturing Hood’s hospital. A brigade of our cavalry after them, supported by a brigade of Stewart’s. Captain Porter, who went with General Johnston, came back. Says last reports represent our troops driving enemy’s cavalry. 1.30 P.M. Heavy musketry and artillery on Hindman’s front; began about fifteen minutes ago. Lieutenant Wigfall has just come up to say enemy are making a very determined attack on Hindman. General Johnston preparing to mount to ride to Hood’s. Firing continuous. 3.30 P.M. Few minutes after writing above rode off to General Hood’s with General Mackall, who accompanied General Johnston. Found Hood where Dalton dirt road and railroad are near each other and where we now are. Hindman, a few minutes after we arrived, repulsed the enemy, who came up in some places to his breastworks. Our reserves not used. Orders given for Stewart to take enemy in flank; for wagons which were sent back to be brought up to Resaca. Stevenson and Hindman to take up movement of Stewart. Featherston brought from Polk’s line, also Maney and —— from Cheatham. These supports came up in very short time. Stevenson, however, sent word that enemy in three lines were preparing to attack Stewart’s centre. 3.40 P.M. (In rear of Stewart’s line near railroad) Stewart directed to receive attack and pursue. But slight skirmishing now;
