Additional Information
Gijsbert Karel Van Dedem was the Dutch ambassador at the court of the sultan of Turkey.The letter in cleartext is in Dutch, the annex is encrypted, and solved on a separate sheet of paper. The use of 4-digit codegroups in a nomenclator of the States-Genral is remarkable. Thers is an unsolved letter by van Dedem from 1809, also with 4 digit codegroups. Was the same codebook used?
