A new fort had been proposed in the 1860 Report on the Defence of the United Kingdom, but this was abandoned. The old line was replaced by a bastioned front of 3 whole and 2 demi-bastions with a wet ditch in front 130ft wide. There was space on the ramparts for 168 guns and the casemates in the flanks could hold 50 more. (5)
