In the middle of the 100 years' War, France's Bertrand du Guesclin reportedly used "countermarch" tactics successfully against the English. Another example was General National Greene's "March to the Dan" through the Carolinas to Virginia (and ultimately back to Guilford Courthouse) against Cornwallis during the American Revolution, over somewhat larger distances. And the classic example, of course, was the Long March of the Communists in China away from the Nationalists to the northwest of China in the mid-1930s. In each case, a weaker force used the factors of time and distance to turn the tables against a stronger attacker. What caused them to succeed?
On the other hand, Vercingetorix apparently failed to use such tactics versus Caesar in Gaul. This is true even though he was covering almost the same general area (and distances) as France's Bertrand du Guesclin (although at a different time period). Could a plausible case have been made that such a strategy might have worked?
