A Lieutenant at Eighteen by Oliver Optic

The whinnying of a horse near the two wanderers attracted their attention, and Fronklyn went over to look at the animal. He found four of them hitched to the trees, all of them wearing cavalry saddles. The sergeant still had his carbine slung at his back. He unslung the firearm, thinking he might have occasion to use it. He knew the lieutenant had reloaded his revolver after making with it the holes across the board which had proved so serviceable to them.

In his report to the Confederate authorities at Richmond, General Crittenden alludes to a battalion of cavalry, of which some officers and privates were absent on furloughs, and of which all but about twenty-five ran away. It is possible that the four troopers who were trying to force the negro to ferry them over the river belonged to the number.
