How did the names of Wolf Cave, Eagle Cave and Death Cave in Germany come from? Where are all those places?

Wolf's den-the name of Hitler's European base camp during World War II. It is said to be a closed small secret room. There is an exhaust fan on it, but the noise is harsh. Turn off the exhaust fan, it's suffocating. Open it, the noise is painful. However, Hitler once commented on it: "This is a rare place in Europe, where I can work freely and quietly."

Between the German city of Rastenberg and the Polish city of Kensen, there is a small town called Grad. A few hours' drive from the town will take you to a forest. During World War II, it was a forbidden area for ordinary people. The name of this forest is "Wolf Shangcai".

A path leads deep into the forest. At that time, both sides of the railway were guarded by soldiers of Hitler's Leibstandarte Division. In order to reduce the attention from the air, there are no tall warning towers and air defense towers in the forest. The railway track extends to a small station "Geerlitz" among tall trees. When you get off there, you will see two special towers standing in the forest. This is the communication tower. In the middle of the two towers, on a small clearing, you can see a huge entrance made of boulder and concrete. From there, it is the wolf's den.

Ying Chao, a sister garden in Bavaria Bay near Austria, is Hitler's convalescent place and secret base camp. 1945 was occupied by American airborne division 10 1.

I really don't know the dead hole, there is no such thing.
