The river at Plymouth is nearly a quarter of a mile wide, and with a sufficient depth of water to float the largest draught gunboats. The shore next the town was supplied with a wharf for landing steamers that navigate the river; but the gunboats, of which there were quite a number stationed there, were usually anchored in the middle of the stream. The town was enclosed with earthworks, with the exception of about two hundred yards on the left next the river which was rather low and marshy, and covered with quite a thick growth of alders and other bushes. On the extreme right, on the bank of the river, was Battery Worth; a small earthwork, just large enough to work a two hundred pound Parrot gun, with which it was supplied, and accommodate twenty or thirty men to handle and support it. This was surrounded with a deep ditch; but on the side next the town it was protected only with a low breastwork with a wooden slat door, and a person could jump across the ditch and step over into the redoubt. Extending south from this small earthwork ran a line of breastworks to the south-west corner of the town, when it turned at right angles, making a continuous line of works nearly two miles in length, completely surrounding the place, with the exception of the short space next the river on our extreme left, as before stated. In the south center stood Fort Williams, a strong work; and some distance from the line of works on the right center was Fort Wessels, a small redoubt. On the left of Fort Williams on the works facing east, were Comphor and Coneby redoubts, one each side of what was called the Columbia road. On each side of Fort Williams, which faced south, were sally ports, on what was called the Washington road and the middle road. In our front, to the south, was an open field for a thousand or twelve hundred yards, the farther part of which was partially covered with the brush and stumps of the newly cleared field, and beyond this was woods. About a mile up the river, on what was called War Neck, as a protection to our extreme right, was Fort Gray, a work of considerable strength, garrisoned by the 96th New York. Such is a brief description of Plymouth as it appeared in April, 1864. Brig. Gen. W. H. Wessels was in command of the post, and Lieut. Commander Flusser was in command of the fleet of gun-boats, which consisted of the Miama, a large wooden double-ender, the Southfield, an old New York ferryboat under command of Capt. French, the Whitehead, Capt. Barrett, the Bombshell, and a small supply boat called the Dolly, with one or two other boats whose names I do not now remember.
