Defence plan for the Surinam River

Title Leupe: Schetsplan van de verdediging der rivieren Suriname en Commowynne.

This is a design for the ‘Obstruction Plan’, that is the closure of the estuary of the Surinam River in time of war, which was worked out in detail during and after the Fourth Anglo-Dutch War, based on first improvised plans dating from 1781-1782. This plan corresponds to the general design for the Obstuction plan, including fire ranges between the fort Nieuw Amsterdam fortress and the redoubts Purmerend and Leyden as well as a fleet of skirmishing vessels.
