Strategic victory
Appearance
A strategic victory is a victory that brings long-term advantage to the victor, and disturbs the enemy's ability to wage a war. When a historian speaks of a victory in general, it is usually referring to a strategic victory.
For example, during the American Civil War, Union and Confederate armies fought each other at the Battle of Antietam. The battle was tactically inconclusive. Both armies suffered about the same amount of casualties, but it stopped the Confederate invasion and was thus a strategic victory for the Union forces.
