We often hide our sources of power from view; what most people consider a center of gravity is often a front. But sometimes an enemy will reveal his center of gravity by what he protects the most fervently. In bringing the Civil War into Georgia, General William Tecumseh Sherman discovered that the South was particularly anxious to protect Atlanta and the areas around it. That was the South’s industrial center of gravity. Like Sherman, attack what the enemy most treasures, or threaten it to make the enemy divert forces to defend itself.
