There were four major Resistance organizations in The Netherlands, and many smaller ones. They did not coordinate their activities unless help from one group to another was absolutely necessary; for the most part they did not answer to a central headquarters. They conducted their operations as they saw fit. For game purposes they have all been put under the umbrella of the primary military-oriented group. A description of some of the partisan groups follows.*
*
"Central Government Organizations For Help To People In Hiding" (LO) was the most important partisan group. Its primary goal was the protection and exfiltration of onkerduikers (Netherlands Jews and young draft-age Dutch men and women). They also kept watch on Dutch collaborators, and engaged in whatever resistance they could without endangering themselves.*
*
While the LO maintained a low profile, the "Central Government Fighting Group" (KP) carried out sabotage operations at the local level. Its estimated strength was 550 members nationally, but this figure is probably low. Without central direction, the KP attacked targets of opportunity in and around the hometowns. It tended mostly to target railroad tracks, telegraph and telephone lines, German supply points, and motor pools, but it occasionally assassinated individual German soldiers and Dutch collaborators.* 
*
A third organization, the "Council of Resistance" (RVV), engaged in both communications sabotage and protection of onkerduikers. Allied planners regarded this group as "sound from the security point of view." With several thousand members, the RVV was in radio contact with the Bureau Inlichtingen (BI), the government-in-exile's intelligence service, and was supplied with arms and ammunition from the Allies.*
*
Another organization, the "Order of Service" (OD), focused on preparing for the return of a Dutch Government following Holland's liberation. The OD was made up primarily of former Dutch officers and government officials who found themselves supplanted by the Nazis and by Dutch collaborators. Its main missions were to collect intelligence and develop "plans for the maintenance of administrative services and civil order on the liberation of Holland."* 
*
A subgroup, the "Dutch Secret Service" (GDN), functioned as an intelligence agency for the OD. There were also some 20 other intelligence entities in wartime Holland. Most Resistance groups conducted some level of intelligence operations, even if it was only counterintelligence for security purposes. When organized at the national level, the groups were divided into regional geographic areas of administration.*
*
At the national level, the National Steunfonds (NSV) was an umbrella financial organization which received money from the government-in-exile and conducted covert fundraising to finance KP and LO operations. There was some overlap in responsibilities among members of the local and regional groups. For example, in the Nijmegen district, the LO commander was also the chief of staff of the district OD.*
*
Almost every town of any size had one or more of these groups. It was also possible for one person to belong to more than one such organization. In some groups, members simply were referred to by nicknames, and their true identities remained unknown. Many of the groups were named after their leader.*
*
Some organizations, established locally by individual Dutchmen, operated with no formal, structured links to any other groups. For example, in Eindhoven, a group known as the "Partisan Action Nederlands" (PAN) functioned along the lines of the KP but did not consider itself part of that organization.*
