Guernsey is an island in the English Channel off the coast of Normandy. It lies roughly north of St Malo and to the west of the Cotentin Peninsula. With several smaller nearby islands, it forms a jurisdiction within the Bailiwick of Guernsey, a Crown dependency. The jurisdiction is not part of the United Kingdom, although defence and most foreign relations are handled by the British Government.

For most of the Second World War, the Channel Islands were occupied by German troops. Before the occupation, 80% of Guernsey children had been evacuated to England to live with relatives or strangers during the war. Some children were never reunited with their families. The occupying German forces deported over 1,000 Guernsey residents to camps in southern Germany, notably to the Lager Lindele (Lindele Camp) near Biberach an der Riß and to Laufen. Guernsey was very heavily fortified during World War II, out of all proportion to the island's strategic value. German defences and alterations remain visible, particularly to Castle Cornet and around the northern coast of the island. The island was liberated on 9 May 1945, now celebrated as Liberation Day across both Guernsey and Jersey.
