A copy of the top secret plan for the liberation of the channel island at the end of the World War 2 has been sold for more than three times the expected price in auction.
The 50-Page documents, the codenamed operation nesteg, were discovered in a cardboard box in Derbyshire in the UK.
Hanson of the auctions described it as a “piece of history”, before it went under the hammer.
The top guide price was £ 1,200, but the auction bid in the auction at Etwall was £ 3,800.
Since June 1940, Jersey, Guernsey, Alderney, Sarak and Haram were in German occupation.
The document referred to British plans for the liberation of the channel islands, including the inclusion of beaches.
The plans were spread over several pages, crossed through some lines, and with other anotations.
First Matt Crosson, Hanson, Told BBC: “This is an incredible story – the document was part of a dusty box of papers in Britain’s Salroom, which was considered negligible.
“But in the examination closely, the seller came into a piece of two history of world war, which was described to free the only Nazi-Kabje area of the British islands.”
The file was formerly the property of Walter Page, the sub-element of the Royal Naval Volunteer Reserve, which was also part of the Normandi invasion.
