Operations & Intelligence (O&I) was a Dutch stay-behind organisation that was founded in 1946/1947 as a result of the resistance against the German occupation during World War II and was disbanded by Prime Minister Lubbers in 1992. In fact, there were two separate organisations, namely Operations and Intelligence , which were eventually coordinated by one person but each had its own task. Until about the mid-1980s, they were simply called O and I, since then service A and service B. In the media, O&I was often compared to the Italian Operation Gladio , from which the Dutch network differed in important respects.

Operations & Intelligence had to keep the population as resilient as possible against communist propaganda, and pass on information about political developments to the 'government in exile'. Furthermore, the organisation had to try to disrupt and mislead the authority apparatus of the occupying forces where possible. Armed resistance was not the primary objective, but when the Soviets approached, the members of the organisation would receive sufficient weapons from hidden depots so that they would not be slaughtered defencelessly. One such underground weapons depot, consisting of 19 crates, was discovered by chance in 1983 in the woods near Rozendaal. Three years earlier, in 1980, a similar weapons discovery had already been made in Haelen.
