The Channel Islands were the only part of the British Isles to
be occupied by Germany in the Second World War.
Although demilitarised by the British government, this was apparently
unknown to the German military authorities at the time and Guernsey
was bombed with significant loss of life.
The German forces occupied Guernsey on 30th June 1940 and remained
the controlling power until liberation on 9th May 1945, the day
after VE day. The island was heavily fortified as part of Hitler's
German military law came into effect immediately, food was rationed,
transport restricted, radio receivers banned, and aiding the "enemy"
was made a capital offence.
Infringements were punished by local imprisonment for minor offences
to deportation, or even execution, for the more serious.
