Following the fall of France and the surrender of Paris on 14 June 1940, the British Government announced that the Channel Islands had no strategic importance and would not be defended. The Germans occupied the islands from the end of June onwards and remained in control until the end of the war. On 10 October 1941 Hitler announced his intention to 'convert them into an impregnable fortress', and the islands formed the most heavily fortified and defended section of the entire Atlantic Wall. This book describes the design, construction and manning of these defensive positions, as well as considering more widely the occupation of the Channel Islands by the Germans.

Incredible as it may seem today, detailed plans were drawn up to recapture the Channel Islands, the most heavily fortified of all the German-occupied territories, regardless of the potentially ‘severe’ loss of life and the widespread destruction to the property of the British citizens. Under the codenames Constellation, Condor, Concertina, and Coverlet, the islands of Jersey, Guernsey and Alderney were to be attacked in 1943. The operation against Alderney would be preceded by a bombardment by between 500 and 600 medium/light bombers and an astonishing forty to fifty squadrons of fighters. The official papers which have now become available state that: ‘The islands cannot be taken without causing some civilian casualties. In the case of Alderney, it is thought that the air bombardment will have to be on such a scale that all personnel on the island will have to become casualties.’ A similar number of aircraft would attack Guernsey while, for the assault upon Jersey, thirty-one squadrons of heavy bombers and strike aircraft would bombard the island’s east and west coasts. This would be followed, on D-Day, by parachute and infantry landings and then a commando assault in the south-west. On Day 2 of the operation the first of the tanks were to land, with more armor and infantry to follow on subsequent days. As the German garrison of the Channel Islands was some 40,000 strong, the islands would be turned into an enormous battlefield, and a vast killing ground. The consequences for the Islanders were almost too horrendous to imagine and the political fallout beyond calculation if the operations failed in their objectives after the devastation and loss of British lives that the fighting had caused. Despite all this, it was thought that such operations would become the ‘second front’ so persistently demanded by Stalin to draw German troops from the Eastern Front and might also help the Allied forces which were about to invade Italy – Operation Husky – from North Africa. Equally, the Channel Islands would be the ideal base for the D-Day invasion of France scheduled for 1944. There was much then in favor of mounting the operations against the Channel Islands regardless of the fact that it meant the death of untold British citizens at the hands of British troops and the Allied air forces. The Allied Assault Upon Hitler's Channel Island Fortress is, therefore, the first detailed analysis of what would have been the most controversial operation ever undertaken by the British and American armed forces.

Osprey's study of the Walcheren campaign of World War II (1939-1945). Walcheren is a saucer-shaped island in the estuary of the river Scheldt, commanding maritime access to Antwerp, the largest port in Western Europe. The Allies captured Antwerp intact on September 4, 1944, but their eyes were on the Rhine crossings at Arnhem, not the lower Scheldt. The failure of Operation Market-Garden later that month brought home the Allies' logistical weakness. As autumn gales drew near, every shell and petrol tin had still to be landed at Cherbourg or across the Normandy beaches. Complete US Army divisions were immobilized for lack of transport. It was vital to re-open Antwerp. The continued German presence on Walcheren, however, prevented Allied shipping from entering the Scheldt. In the fall of 1944, Walcheren had the most heavily fortified coastline in the world. Its seaward defences consisted of 30 coastal and field batteries, mounting 50-60 guns from 75mm to 220mm in caliber, manned by high quality naval personnel behind massive concrete emplacements. Supporting strongpoints had anti-aircraft guns, flame-throwers rocket-launchers and Goliath remote controlled demolition vehicles. The sand dunes protecting the low-lying island from the North Sea were laced with barbed wire, mines and dragon's teeth. Defending infantry came from Generalleutnant Wilhelm Daser's 70.Infanterie-Division, a 'white bread division' consisting of men with gastric problems. Allied intelligence estimated the total garrison at 4,000, but 8,000 eventually surrendered. On November 1, 1944, in a double-pronged attack, the men of 52nd (Lowland) Division plus No. 4 Army Commando seized Flushing (Infatuate I) while in the west 4th Special Service Brigade with three Royal Marine Commandos and No. 10 Inter-Allied Commando would take Westkapelle, and fight their way north and south along the dunes, taking the coastal batteries as they went (Infatuate II). All this was to be supported with HMS Warspite and two 15-inch gun monitors; the Support Squadron Eastern Flank (SSEF) with 25 specialized Landing Craft with guns and rockets; 350 Army guns south of the Scheldt, most of them heavier than 25-pounders; and the Typhoon and Spitfire fighter bombers of 84 Group RAF. In fighting described by one survivor as 'worse than Dieppe and D-Day put together' the Army and Royal Marines forced their way ashore, supported by specialized armour and tracked vehicles, and over the next eight days cleared the positions of their German defenders in bitter street fighting. The first Liberty ships unloaded at Antwerp on December 1, just over a fortnight before the Ardennes offensive began. If Walcheren had not fallen when it did, opening Antwerp just in time, the Allies would have been hard pressed to withstand the German attack, or replace the fuel stocks lost in its opening days, let alone cross the Rhine in the following spring, and meet the Russians on the Elbe. The Walcheren campaign was not merely a dramatic combined operation pulled off against the odds; it helped determine the course of the war and the shape of the post-war world.
