The batteries were nearly all provided with bomb-proof magazines, but with no protection for the men except the low parapet. From Battery No. 1 to 11 it was a little over one mile.
A system of land defenses had been planned, and work slowly progressed during the winter of 1862-3. The full plans of the engineers were never carried out, and at the commencement of the siege the works on the northern side had not been begun. As planned the defenses began at Battery No. 11 and extended in a semi-circular direction for a distance of over four miles, striking the river near the mouth of Sandy Creek, about one mile above Battery No. 1. The earthworks, where completed, consisted of a crémaillère line, broken by occasional lunettes and redans for artillery. Where the ground was open and favorable to assault, the ditch was from three to four feet deep and five or six feet wide. From the bottom of the ditch to the top of the parapet it was, in no case, more than seven or eight feet, except when increased by the natural features of the ground, as in front of Battery No. 11, where there was a deep ravine. In Northern publications, maps are given showing a very complete system of defenses, with inner and outer lines, but these, if planned, were not constructed—there being but a single line of works, except that during the siege inner lines were constructed across points mined by the enemy, as at the northeast angle and Battery No. 11.
