Anyone interested in a detailed source of information about the Royal Netherlands Navy during the period 1939-46 will want to visit the Dutch national archives. They have a massive digital, on-line copy of an unusual source created in the late 1950s and early 1960s by the RNethN's history office (Bureau Maritieme Histoire or BMH). This series is called Marinemonografie and consists of four volumes: Netherlands, Western Europe, Netherlands East Indies, Netherlands West Indies. Each volume has numerous chapters about specific time periods, ships or services within the RNethN such as submarines or naval aviation. The volume for the NEI has a war diary beginning in August 1939 showing what the RNethN knew of its own forces and Allied or Japanese forces. There are sections for diplomacy, equipment, personnel, intelligence, etc. for each day. Ship movements are given for the RNethN and Gouvernementsmarine on a daily basis. This series is a tremendous resource for anyone interested in a particular part of the world, branch of the RNethN or ship. Many of the chapters within each volume are appendices that give the original source material used for the narrative. So you can read diplomatic messages and naval orders. Some of the chapters for the Netherlands volume list senior officers, staff officers and ship commanding officers in major fleet areas such as Den Helder, Hoek van Holland, Ijmuiden and Vlissingen in May 1940.
