ground in which some of our batteries were going into position, our brigade reached the skirt of a piece of woods, in the farther edge of which there was a heavy musketry fire, and when about to go forward into line we received from Colonel Vincent, commanding the brigade, orders to move to the left at the double-quick, when we took a farm road crossing Plum Run in order to gain a rugged mountain spur called Granite Spur, or Little Round Top. The enemy's artillery got range of our column as we were climbing the spur, and the crashing of the shells among the rocks and the tree tops made us move lively along the crest. One or two shells burst in our ranks. Passing to the southern slope of Little Round Top, Colonel Vincent indicated to me the ground my regiment was to occupy, informing me that this was the extreme left of our general line, and that a desperate attack was expected in order to turn that position, concluding by telling me I was to "hold that ground at all hazards. " This was the last word I heard from him. In order to commence by making my right firm, I formed my regiment on the right into line, giving such direction to the line as should best secure the advantage of the rough, rocky, and straglingly wooded ground. The line faced generally toward a more conspicuous eminence southwest of ours, which is known as Sugar Loaf, or Round Top. Between this and my position intervened a smooth and thinly wooded hollow. My line formed, I immediately detached Company B, Captain Morrill commanding, to extend from my left flank across this hollow as a line of skirmishers, with directions to act as occasion might dictate, to prevent a surprise on my exposed flank and rear. The artillery fire on our position had meanwhile been constant and heavy, but my formation was scarcely complete when the artillery was replaced by a vigorous infantry assault upon the center of our brigade to my right, but it very soon involved the right of my regiment and gradually extended along my entire front. The action was quite sharp and at close quarters. In the midst of this, an officer from my center informed me that some important movement of the enemy was going on in his front, beyond that of the line with which we were engaged. Mounting a large rock, I was able to see a considerable body of the enemy moving by the flank in rear of their line engaged, and passing from the direction of the foot of Great Round Top through the valley toward the front of my left. The close engagement not allowing any change of front, I immediately stretched my regiment to the left, by taking intervals by the left flank, and at the same time "refusing" my left wing, so that it was nearly at right angles with my right, thus occupying about twice the extent of our ordinary front, some of the companies being brought into single rank when the nature of the ground gave sufficient strength or shelter. My officers and men understood my wishes so well that this movement was executed under fire, the right wing keeping up fire, without giving the enemy any occasion to seize or even to suspect their advantage. But we were not a moment too soon; the enemy's flanking column having gained their desired direction, burst upon my left, where they evidently had expected an unguarded flank, with great demonstration. We opened a brisk fire at closes range, which was so sudden and effective that they soon fell back among the rocks and low trees in the valley, only to burst forth again with a shout, and rapidly advanced, firing as they came. They pushed up to within a dozen yards
