A Lieutenant at Eighteen by Oliver Optic

The soldiers on both sides were already engaged in removing the dead to the side of the road next to the woods, and the wounded to the respective hospitals, which had been established in the fields of the farmer. The riflemen had heard the recall, and followed the defeated cavalrymen, bearing their wounded, and handed them over to the surgeon, who had called in three medical students to his aid. Lieutenant Ripley had handled his sharpshooters so skilfully that not a single man had been killed, and only three had been wounded.

He had kept his force behind the trees, and fought the enemy at long range, in which the carbines and other firearms were not effective; and this policy explained the absence of all fatalities in Ripley's force. The three wounded men were not severely injured, and only one was disabled.
