The second case shows actual military value: during the Great Gallic War the Gauls under Vercingetorix planned to lure the Roman armies into Gaul and then trap and obliterate them. They thus ravaged the countryside of what are now the Benelux countries and France. That caused immense problems for the Romans, but the Roman military triumphs over the Gallic alliance showed that alone not to be enough to save Gaul from subjugation by Rome.
