Defence plan for Suriname

Title Leupe: Plan van verdediging der rivieren Suriname en Commowyne enz.

These drawings by N. Robaté are part of a series constituting a plan for the improvement of Surinam's defences. Depicted here is a design for detecting hostile vessels on water via a pole with a barrel at its bottom and a wire at its top. The poles could be used for the ‘Obstruction Plan’ too, that is the plan for 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, using the 1781-1782 first improvised set-up for its realization. The sketches depict the pole at low and high tide. The drawing at the left side also includes a profile of the barrel and the device used to tighten the wire. An elaborate report of Robaté found under the same inventory number provides more details on these plans.
