This dossier contains extracts from the Security Service (MI5) files on the use of pigeons in the World War Two period. Contains papers on MI5's suspicions about the Nazi use of pigeons to communicate with infiltrators and spies in Britain, and the falcon squadron set up to intercept incoming Nazi pigeons.
Also contains papers from the ad hoc committee on postwar pigeon policy, set up to examine future possible uses of pigeons for covert warfare. Among the policies considered were the use of pigeons as suicide bombers, and as a means of delivering biological weapons.
