The 'Iran Cover Plan' was a British deception plan designed to shield part of the British concentration for the UK’s part in the Anglo/Soviet 'Countenance' invasion and occupation of Iran (July/August 1941).
A programme of rumours and 'leaks' was crafted and implemented to suggest that an Indian division known to be leaving India was bound for Basra in Iraq by sea before moving overland to Palestine, and additional support for this deception was provided by the establishment of supply dumps along the overland desert route which the division would have to use in the area of Iraq and Palestine.
