May 16. For some time past the pickets of the 17th Massachusetts have been a good deal troubled by being fired on in the night. The enemy’s cavalry would come down, a few of them dismount and creeping up would fire on them. They would sometimes have cow bells with them, in order to divert attention and get nearer. But the boys soon learned that dodge, and when . they heard a cow bell, would draw their straightest bead on it and let fly. In this state of affairs it was thought best to make those fellows a call, and if they wanted anything of us to give them an opportunity to take it. So, yesterday morning, we marched out to the Trent road, where we joined the 17th Massachusetts, with five companies of the 3d New York cavalry and a section of a battery the whole under command of Col. Amory, of the 17th. The cavalry taking the advance, we marched up the road a couple of miles, coming to a deep gully or ravine; crossing this, the advance cavalry guard soon came upon the enemy’s pickets, driving them in and beyond their station into a swamp, where they formed an ambuscade, thinking there was only a small cavalry force and that they might capture them. By this time the infantry had come up to their rendezvous, which was a large, nice house, with ample barn room for their horses. Thinking this was too good accommodation for them and too near our line, it was set on fire and burned. We now heard firing ahead and hurried on. They had closed around the advance cavalry guard, and commenced the fight. The other companies being close by soon took a hand in it and were giving them about all they wanted when the infantry came up. When they saw the infantry and artillery they took to their heels towards Trenton, a small village a few miles distant.
Col. Upton wanted to follow them up and give them some more, but Col. Amory being in command, thought we had accomplished our purpose and had better return. In this skirmish the enemy lost eight killed and two prisoners, one of them wounded. Our cavalry had two wounded. The wounded men were brought out and loaded into an ambulance. When they brought out the wounded rebel they put down the stretcher on which he was lying near where I was standing. He was a smooth-faced, fair-haired boy, and was moaning piteously with pain from a bullet wound in his head, and asking himself what his mother would say when she heard of it. His thoughts turned on his home and of his mother. I pitied the boy, but could not help thinking, as a cavalryman told him, he should have thought of that before being caught here., We arrived back in camp late in the afternoon, tired, hungry and covered with mud. I reckon they will not disturb our pickets any more at present in the way they have done. Creeping up in the dark and firing on a lone picket is mean and cowardly. If they want anything of us let them come in force and get it; that is proper and honorable.
