Operation Greenup

The Third Reich is collapsing under the relentless advance of the Allies from the west and Soviet troops from the east.

However, the situation in the Alps is different. The Nazi high command intends to resist to the end in the so-called "Alpenfestung" (Alpine Redoubt), a supposed impregnable fortress, which is located in the Tyrolean mountains, where Hitler plans a desperate last stand.

The Office of Strategic Services (OSS) of the US Army recruits three men: Fred Mayer (a German Jew), Hans Wijnberg (a Dutch-born Jew), and Franz Weber (a Wehrmacht deserter).

Main mission: parachute into the area, infiltrate into the village of Oberperfuss, and unveil the truth about the said "Alpine Redoubt."

This adventure is inspired by a real World War II military operation. While the core facts remain, much of the story has been fictionalised.
