During the German occupation of the Channel Islands, there was limited resistance. The islands had a very high number of German soldiers compared to the civilian population, one soldier for every 2-3 civilians, which reduced options; this linked to the severe penalties imposed by the occupiers meant that only forms of non-lethal resistance were used by the population. Even so, over twenty civilians paid the ultimate price for resistance against the occupiers.
From the British declaration of war on Germany in September 1939 until May 1940, a number of Channel Islanders had left to volunteer for the armed forces in England or to work in associated war industries, whilst English people came to the Channel Islands on holiday.
On 10 May 1940, Nazi Germany invaded France and the Low Countries. The Blitzkrieg (Lightning War) tactics took the Western powers by surprise. By the time of the resignation of the French Prime Minister Paul Reynaud on 16 June, it was obvious that Germany victory in the Battle of France was inevitable. In the Channel Islands, civilians worried about the consequences of remaining on the Islands but, to avoid panic, were told by the authorities to stay put. Senior officials were ordered to stay in order to maintain order and to keep the Government functioning. On the 15 June, the British government decided to demilitarise the Islands, evacuating the British garrisons and leaving them undefended. The Germans were not informed however. Evacuation boats for civilians only became available on 20 June and again, to stop a panic, people were still told to remain where they were and that only women and children should be taken. Only when the Lieutenant Governors of the islands evacuated were the recommendation relaxed. The last official ships sailed on 23 June.
In total 17,000 from Guernsey, 6,600 from Jersey and all the 1,400 on Alderney travelled to England. The size of the evacuation inevitably reduced the pool of potential active resistors in the Islands once the Germans landed and began their occupation on 30 June 1940.
