decisive battle

War-ending major engagement

A decisive battle is a military engagement that determines the outcome of a war or campaign.

Unlike inconclusive fighting that leaves both sides capable of continuing, a decisive battle breaks one side's ability or will to fight: Waterloo was the decisive battle that ended Napoleon's rule.

The phrase appears in strategic discussions about whether modern warfare still produces such clear turning points.
