Plans and profiles of the redoubt Leiden

Title Leupe: Plan van de Redout Leyden met de aldaer geprojecteerde veranderingen.

Just as in the case of the redoubt Purmerend, it quickly became apparent that the redoubt Leiden was far too weak to offer any serious opposition to a naval attack through the mouth of the Suriname River. When he made the plan for Leiden as part of his 1781 general defence plan (see VEL2007A), Johann Friedrich Ferdinand Wollant seized the opportunity to propose a few adjustments, to eliminate the defects in the poorly designed rear side of the redoubt. This project plan suggests a counterscarp with a covered road could be constructed to be defended by ‘small arms’, that is infantry men with handheld firearms, plus an extra, small ravelin on the landward side. This plan was never carried out. The Leiden redoubt remained unprotected on its northern side, and, along with the redoubt Purmerend, easily fell to British troops during an 1804 attack.

North is up.
