Diary of Major Joseph Stockton, June 25, 1863

For some time General Logan's division of McPherson's corps had been mining under the rebel Fort Hill, one of the most prominent works and one capable of doing us a good deal of mischief. It was decided to explode the mine today and if the breach was sufficient, to go in as far as possible. We were all drawn up in line of battle to assist Logan or make a diversion in his favor if need be while all the batteries were to open on the rebel works to keep them engaged. He had 2200 pounds of powder in barrels in the mine but their fort was a strong one being at least twenty-four feet thick, of clay and sand. About four o'clock the mine was fired and was in a measure a success. There was no noise but an immense cloud of dirt, interspersed with bodies of men, thrown high in the air. At the same time firing from batteries and rifle pits was tremendous. Our men—the 45th Illinois—rushed into the breach which was made, but a partition of earth some three or four feet thick was blown up, over which our men fought all afternoon and night. Numbers were killed and wounded on both sides, but they held their ground. At night our regiment was ordered out to the advance works in our front, and which was not more than 40 feet from their works, where we remained all night and had two men seriously wounded by their hand grenades. To rest was impossible, as shells from our own and rebel batteries passed over our heads every few minutes; sometimes the shells would explode prematurely and the pieces fly among us; our escape was miraculous. We were in direct range of the different batteries; for instance: There were batteries planted at four different corners and we are in the center and the firing at each other, beside the thousands of minie bullets striking all around us, can give one an idea of how we were situated. We (Ransom Brigade) are also mining a fort in our front and will soon have it done. We are some 30 feet under ground now.
