This timelapse is made from the Twelfth Army Situation maps that were made on a daily basis for General Omar Bradley. Each day unique map was made to show the friendly and enemy positions, the frontline, as well as flanking units. It is important to note that Bastogne is only shown as being surrounded for two days, and not the almost week of being cut off.
This is most likely due to the rapidly changing situation in the Ardennes and the fact that Twelfth Army Group would not have been in communication with many of the units to paint a whole picture.
I am interested to know what people think of the timelapse and their thoughts on the maps.
As a bit of a background, I work professionally with the military and produce these type of maps on a regular basis so I find it particularly interesting.
