It would be another two years before the destructive warfare finally ended, but in the meantime Wincklemann's own priorities turned back to scholarship, and he made a proposal to the Landgrave that he should prepare a comprehensive history of the Hesse-Darmstadt Landgraviate.

[1] He set to work with energy, acquiring a number of manuscript chronicles, procuring copies of important documents, copying inscriptions and travelling extensively, because he was also keen to be able to include descriptions of the land and its people, and to observe for himself the towns and fortresses, antiquities and monuments, mines and manufacturing operations.

A work he completed at his new patron's instigation was "Oldenburgische Friedens- und der benachbarten Oerter Kriegshandlungen".

By this time, however, interest had cooled in the more socio-economic aspects of the works, covering matters such as agriculture, land use and manufacturing, and many of the maps and drawings that he had gathered went unused.

Nevertheless, by the time he died, in deep poverty, on 3 July 1699, a sixth volume incorporating some of these elements had been prepared and was ready for printing.
