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 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 close 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 of us before the terrible effectiveness of our fire compelled them to break and take shelter.
They renewed the assault on our whole front, and for an hour the fighting was severe. Squads of the enemy broke through our line in several places, and the fight was literally hand to hand. The edge of the fight rolled backward and forward like a wave. The dead and wounded were now in our front and then in our rear. Forced from our position, we desperately recovered it, and pushed the enemy down to the foot of the slope. The intervals of the struggle were seized to remove our wounded (and those of the enemy also), to gather ammunition from the cartridge-boxes of disabled friend or foe on the field, and even to secure better muskets than the Enfields, which we found did not stand service well. Rude shelters were thrown up of the loose rocks that covered the ground. ...
The enemy seemed to have gathered all their energies for their final assault. We had gotten our thin line into as good a shape as possible, when a strong force emerged from the scrub wood in the valley, as well as I could judge, in two lines in echelon by the right, and, opening a heavy fire, the first line came on as if they meant to sweep everything before them. We opened on them as well as we could with our scanty ammunition snatched from the field.
It did not seem possible to withstand another shock like this now coming on. Our loss had been severe. One-half of my left wing had fallen, and a third of my regiment lay just behind us, dead or badly wounded. At this moment my anxiety was increased by a great roar of musketry in my rear, on the farther or northerly slope of Little Round Top, apparently on the flank of the regular brigade, which was in support of Hazlett's battery on the crest behind us. The bullets from this attack struck into my left rear, and I feared that the enemy might have nearly surrounded the Little Round Top, and only a desperate chance was left for us. My ammunition was soon exhausted. My men were firing their last shot and getting ready to club their muskets.Now comes the moment when Chamberlain assured his place in Valhalla:
It was imperative to strike before we were struck by this overwhelming force in a hand-to-hand fight, which we could not probably have withstood or survived. At that crisis, I ordered the bayonet. The word was enough. It ran like fire along the line, from man to man, and rose into a shout, with which they sprang forward upon the enemy, now not 30 yards away. The effect was surprising; many of the enemy's first line threw down their arms and surrendered. An officer fired his pistol at my head with one hand, while he handed me his sword with the other. Holding fast by our right, and swinging forward our left, we made an extended right wheel, before which the enemy's second line broke and fell back, fighting from tree to tree, many being captured, until we had swept the valley and cleared the front of nearly our entire brigade.
Meantime Captain Morrill with his skirmishers sent out from my left flank, with some dozen or fifteen of the U.S. Sharpshooters who had put themselves under his direction, fell upon the enemy as they were breaking, and by his demonstrations, as well as his well-directed fire, added much to the effect of the charge.
Having thus cleared the valley and driven the enemy up the western slope of the Great Round Top, not wishing to press so far out as to hazard the ground I was to hold by leaving it exposed to a sudden rush of the enemy, I succeeded (although with some effort to stop my men, who declared they were "on the road to Richmond") in getting the regiment into good order and resuming our original position.
Four hundred prisoners, including two field and several line officers, were sent to the rear. These were mainly from the Fifteenth and Forty-seventh Alabama Regiments, with some of the Fourth and Fifth Texas. One hundred and fifty of the enemy were found killed and wounded in our front.Chamberlain was awarded the Congressional Medal of Honor.
Chamberlain's memoir of the battle, Through Blood and Fire at Gettysburg, is well worth reading. As a university professor, Chamberlain was one of the best-educated soldiers to fight in the war and wrote a superb account of the fight. I would also recommend Conceived in Liberty: Joshua Chamberlain, William Oates, and the American Civil War, which is a dual biography of Chamberlain and the Alabama officer who commanded the Confederate troops opposing him on that fateful day. Finally, of course, Chamberlain is one of the heroes of Michael Shaara's classic novel The Killer Angels .
