A file of memoranda discussing possible measures to reduce Jewish migration to Palestine. Among the options suggested are legal action against the crews of the ships transporting the emigrants, and a whispering campaign intended to dissuade Jews from wanting to go. The latter is accompanied by suggestions that the rumours be linked to a "powerful Arab underground organisation", the staging of fake ‘murders’ of emigrants in Palestine, and that sabotage be carried out on the ships, including tampering with their food and water, and setting fire to ships in port.
