Abstract
The decades-long contamination of Gruinard Island by anthrax is now a well-known part of the history of biological weapons (BW) development, as well as that of military encroachments in the Scottish Highlands and Islands (and the authorities' rather less persistent efforts at damage limitation). Some accounts have included the related episode, reportedly well-remembered by local people, of anthrax contamination on the mainland close to Gruinard. This occurred in 1942-43, when BW experiments were conducted on the island as part of the war effort by scientists from Porton Down under the auspices of the British government. After much top-level discussion, payments were made to the owners of animals that had died as a result of the contamination. The episode had a bearing on discussions about the future of the island and on subsequent policy with regard to the siting, conduct and secrecy of BW experiments.
