Following the withdrawal of defences by the British government and German bombardment, Jersey was occupied by German troops between 1940 and 1945. The Channel Islands were the only British soil occupied by German troops in World War II. This period of occupation had about 8,000 islanders evacuated, 1,200 islanders deported to camps in Germany, and over 300 islanders sentenced to the prison and concentration camps of mainland Europe. Twenty died as a result. The islanders endured near-starvation in the winter of 1944–45, after the Channel Islands had been cut off from German-occupied Europe by Allied forces advancing from the Normandy beachheads, avoided only by the arrival of the Red Cross supply ship "Vega" in December 1944. Liberation Day - 9 May is marked as a public holiday.
