There is a new film available on YouTube on Friday Sept 24 on the Shetland Bus operations.
For those that are not aware because the US certainly doesn't study this as part of WWII, Norwegian fishermen escaped from coastal Norway to Shetland when the Germans moved in, then were recruited by the Royal Navy to make trips across the North Sea in their fishing boats including in winter and in the dark (easier to evade German warship patrols). They carried guns, ammo, money and covert operatives over and brought back refugees. This is an absolutely fascinating history.
I hope all the Shetland lovers will enjoy this and that it will tell a WWII story many of us don't hear until visiting Shetland.
There is also a good book on the topic called The Shetland Bus by David Howarth which is available as an e-book.
