German Fallschirmjager paratrooper Paul Brand and his junior sergeant Max Grun are sent to a clandestine camp in the foothills of the Harz Mountains to undergo intensive training for their mission - the subjugation of the impregnable Eben Emael Fortress. The top-secret mission involves two classified weapons: a glider used for the first time to deposit troops directly onto target, and a new Hollow Charge Weapon, capable of blasting through steel or concrete. Standing between them is over 1,000 Belgian troops. Will they succeed in their mission and penetrate the strongest fortress in the world? Or will the Belgian troops and their secure bastion be too strong? Join Paul and Max in the first of their wartime missions and follow them in the Devils with Wings series. This exciting fictionalised retelling of the assault on Eben Emael is written by an author with extensive army intelligence experience.
