‘Operation Legacy’: Britain’s Destruction and Concealment of Colonial Records Worldwide

The end of the British Empire in the mid-twentieth century was accompanied by a large-scale rearrangement of sensitive colonial records worldwide. A great number of these records were destroyed and a sizeable portion sent to Britain to be kept secret. This article advances studies of this policy, eventually code-named ‘Operation Legacy’, by reading the ‘migrated archives’ that have been newly discovered and declassified in the Foreign and Commonwealth Office (FCO) 141 series. It asks where the policy was decided, for what reason and how it was carried out. Sources suggest that the policy was not planned in the Colonial Office in London and delivered to the colonies in a hierarchical fashion, but, rather, significant elements of the policy were developed in the colonial governments overseas in response to each local context. The general idea was to save Britain’s honour and to protect its collaborators. However, the limitations in terms of time and manpower often prevented the officers from putting sufficient thought into the actual screening of the documents. At the same time, some officers demonstrated a level of historical awareness regarding their actions. The episode reminds us that the official mind as it relates to decolonisation is to be understood not only by reference to the highest levels of strategic planning but also in terms of how it worked at the lower levels, in the colonial administrations on the ground.
