What is the cinquieme bureau?

The Cinquième Bureau, or Fifth Bureau, was a French intelligence agency established in the early 20th century, primarily responsible for military intelligence and espionage. It played a crucial role during World War I and II, focusing on gathering information about enemy forces and potential threats. The bureau was later absorbed into other intelligence organizations as the structure of French military intelligence evolved. Its legacy reflects France's ongoing efforts to enhance national security through information gathering and analysis.
