Hitler’s Atlantic Wall

During World War II, Hitler saw The Channel Islands Occupation as part of a strategic defence strategy and formed plans to militarise them as part of a huge Atlantic Wall against Britain. Occupying forces moved in for 5 years from 1940 until 1945, creating a huge and lasting presence on both the islanders and the islands.

Occupation on each island

By 1940, The Channel Islands were being promoted as tourism destinations in an effort to boost the morale of British Citizens. However when the Battle of France took place in June, 46 Whitley bombers were sent from Guernsey and Jersey to assist efforts in Italy. When the battle was lost, Winston Churchill took the decision to de-militarise the islands, unbeknown to Hitler. As bombs began to fall on 28 June 1940, in the ensuing confusion, authorities on each island took their separate decisions as to whether evacuation was necessary. Guernsey prepared to evacuate its children with parents given an option to go with them, Herm remained relatively unscathed and Sark’s Dame, Sybil Hathaway, chose to treat the new occupants as guests. In Jersey the majority of the population stayed whilst Alderney residents were ordered to evacuate entirely. By 1st July, Nazi flags were flying high on all the islands.

The Channel Islands, a military history

As you visit the Channel Islands today, you can’t fail to notice military looking fortifications dotted around the coastlines. The Channel Islands have a long military history of being variously claimed by Britain and France and many fortifications date back to Napoleon’s time. When German forces entered during World War II, many of the former military sites were adapted for new purpose. There are a number of excellent museums in Jersey and Guernsey which bring to life events of the time.
