to Sharpsburg, almost in the rear of the rebels. Some of our troops even penetrated to Sharpsburg itself, and were taken prisoners. A short distance farther would have cut off the enemy's direct retreat to the Potomac. Rebel troops were seen hurrying on the road to the river. Our men were now fired upon by artillery, and attacked by fresh bodies of infantry coming up, as the enemy say in their account, from Harper's Ferry. Our brave fellows, however, stood their ground, waiting for reenforcements, which Burnside called for. But McClellan, unfortunately, dared not throw in his reserves; his object had probably been gained in making a diversion from the hard contested field on our right. Our gallant fellows had to stand there unsupported until their ammunition gave out; they fired their sixty rounds of ammunition, collecting all they could from their dead and wounded comrades, and then began to retreat. Benjamin's battery of artillery was also short of ammunition, and could not support them. Our brave boys only retreated to the next hill, not to the hill above the Antietam, and then lay on their arms during the night, and there they stayed during the next day, expecting the order to advance. Little mounds of earth, covering fallen heroes, point out the course of our soldiers all the way from this side of the Antietam to the top of the farthest hill. Here our men were so much more exposed than the rebels that our loss was greater than theirs. On the right the rebel loss was much the larger. In the battle beyond the river, the Hawkins Zouaves, another of the regiments distinguished in North Carolina, captured a rebel battery at the point of the bayonet. In the rebel account we are told how the brave General Toombs, with a whole brigade, retook the battery and defeated this single regiment, which they magnify into an immense force. General McClellan, with all his knowledge and great skill and success in defensive warfare, as shown in his Peninsular campaign, after our defeat at Gaines's Mill, is wanting in the rapidity of comprehension and audacity which are necessary components of the highest military talent. He waits for too many chances, and fears any risk.
