The Thule Society's headquarters was a massive European-style manor.
In the surrounding open area, there were several machine guns behind piled up sandbags. These machine guns covered the front door of the manor, making it easy to defend and difficult to attack.
At this moment, perhaps the German troops here had already received the news, and they appeared very nervous. Even at four o'clock in the morning, they were still on high alert. The searchlights on the roof of the manor were sweeping the surroundings back and forth, and many German officers dressed in SS uniforms were loudly commanding the soldiers to increase their fortifications.
According to the intelligence the Allies obtained, the Thule Society's headquarters was underground, and this manor had a passage for escape, so after splitting up some people to guard the exit of this passage, the remaining people followed Roy and attacked the manor!
