Mr Dorey was the youngest of four brothers living at Brooklands Farm, in Kings Mills, during the Nazi Occupation of Guernsey in 1940.
He said farmers had to take milk to a depot at Myrtle Place, which is now the Fleur du Jardin Hotel.
He said: “Of course all the news and all the gossip was had from taking the milk twice a day.
“I think the Germans were all a bit frustrated as [our talking] was all in Guernsey-French and they just couldn’t make anything out.”
