The enemy's line was along one of the smaller branches of Pumpkin Vine Creek, and Sherman ordered for the 27th that McPherson should press toward the left down the little valley, whilst Howard, with one division of his own corps withdrawn from the line and one division of Palmer's which had been in reserve, should push out beyond our left and turn the enemy's right near Pickett's Mill. A brigade of the Twenty-third Corps moved in the interval to cover Howard's flank and keep connection with the intrenched line. The almost impenetrable character of the forest made the movement slow, and it was late in the afternoon when Howard reached the enemy's position. He found they too had been busy in extending their lines, though pretty sharply recurved, to the eastward. The fierce combat did not succeed in carrying the Confederate position, but it gained good ground near the mill, better covering all the roads toward the railway. The left wing of the Twenty-third Corps swung forward to Howard's position, and all intrenched strongly upon it. On May 28th McPherson was ordered to prepare for moving to the extreme left, continuing the extension of our line toward the railroad. Suspecting this, the Confederates made a fierce attack upon the position in front of Dallas, but were repulsed with heavy loss. At McPherson's request his movement was delayed a little, lest it should seem to be forced by Johnston's attack. [Footnote: Official Records, vol. xxxviii. pt. iv. pp. 339, 340.] Sherman had been very unwilling to give up the hope of putting Johnston's army to rout in a decisive engagement, and to accept, instead, the patient flanking movements by which he should force upon his adversary the dilemma of abandoning more and more of Georgia, or of himself making attacks upon intrenched lines. In writing to Halleck after the battle of Resaca, he had said that although the campaign was progressing favorably, he knew that his army "must have one or more bloody battles such as have characterized Grant's terrific struggles." [Footnote: _Id._, p. 219.] But the affairs at New Hope Church and Pickett's Mill show that the country was so impracticable that it was not possible to deliver an attack by his whole army at once, and so to give real unity to a great battle. He was therefore brought, perforce, to accept the systematic advance by flanking movements, and to avoid assaults upon intrenched positions on the forest-covered hills. He knew that this policy would bring a time when the enemy could no longer afford to retreat and must resort to aggressive tactics, even at the risk of destruction to his army. It was a curious repetition of the ancient colloquy,--"If thou art a great general, come down and fight me.--If thou art a great general, make me come down and fight thee." It may be readily admitted that in such a country as Central Europe other methods would have been feasible and preferable; but in the tangled wildernesses of Virginia and Georgia
