The first shock fell upon Ward's brigade, which held the extreme left at the Devil's Den. Ward's line would not reach to Little Round Top, so that there was a wide space between him and this hill, with not a man in it--a fact that Hood's men were not slow either in perceiving or taking advantage of. But, what was far worse, it led to the discovery of the defenceless condition of Little Round Top itself, and, quickly grasping its commanding importance, the enemy instantly sent one of his brigades to seize it. The conflict thus established at this point, which Sickles had so imprudently vacated, became of supreme importance to the Union army, while that about to begin at the peach orchard degenerated into a struggle to save Sickles' corps from annihilation. Fortunately for Ward, the ground he held was just the place for a protracted defence, provided he should not be out-flanked. Weird and grisly, it looked as if some huge excrescent mass of earth, rocks, and trees had some time slid off the flank of Little Round Top into the low ground below, whence its own momentum had carried it still farther on--a misshapen heap, deeply seamed by rents and splits, thick-set with bowlders and filled with holes and hiding-places, among which Ward's men now found excellent cover. [Sidenote: The Danger Point.] Ward was firmly planted on and around the Devil's Den, with his sharp-shooters loading and firing from behind the scattered bowlders, when the enemy made their rush upon him, whooping and yelling like so many fiends come to reoccupy their own legitimate abode. Some portion soon found themselves in the unguarded hollow below. Seeing the enemy crowding into it, Ward sent first one regiment there, and then another, on the run. A combat at close quarters ensued. The regiments of Hood's division were now either trying to scale Little Round Top, push through the hollow, or capture the Devil's Den with its guns. The left brigade, however, which extended beyond the Den, was being very roughly handled; the centre only had made progress, while the right was engaged in a murderous conflict, to be presently described. Hood's effort had, therefore, exhausted itself, and his division had to halt simply because it could advance no farther. [Sidenote: At the Wheat-field.] McLaws now came to Hood's assistance. His right brigade (Kershaw's) now struck De Trobriand's, which stood next in line along the edge of a wheat-field, back of and adjoining the Devil's Den. De Trobriand had a little muddy ravine in front of him, into which the enemy boldly plunged. His men waited until their assailants had got within twenty yards, when they poured in such a close and deadly fire that the gully was speedily vacated by all save the dead and the dying. The attack here not only completely failed, but three of Kershaw's regiments were nearly destroyed while attacking the peach orchard. This brigade fell back and was rallied about the Rose house.
