BAB21 Blechhammer was evacuated on the 21st January 1945.   Due to heavy snow the men had to turn back and try again the next day leaving the camp successfully on the 22nd.    When the routes are placed side by side,  the rest days seem to indicate organisation during the march.  Often, when a group took a short rest break during the days march,  another group would pass by to great cheers and cat calls from the resting men.

The top 35 metres of chimney were then removed to solve the problem which it did.  The drawback was that bombs were dropped on the total smoke area including all the camps.  Another danger was unexploded bombs in the vicinity of the camps after each raid. ...
