The First Lines
During 1756 and 1757 defensive lines were constructed on the Portsea Island side of the creek under the supervision of John Peter Desmaretz. They consisted of a 15–20-foot-wide (4.6–6.1 m) and 6-foot-deep (1.8 m) ditch backed by a 7–8-foot (2.1–2.4 m) rampart. Water could be allowed to flow into the ditch from sluices at either end.
