Describe a real or imagined example of a pyrrhic victory

For those who might not be familiar with the term, a Pyrrhic victory is technically a win, but the results of the victory or the casualties incurred in the process of achieving the victory are absolutely devastating to the victor, either physically or emotionally, to the point where calling the campaign a victory is arguable depending on the observer’s perspective.Pyrrhic victories are popular in works that take place in a darker or more cynical setting. They pop up in almost all of Shakespeare’s tragedies (Hamlet is a great example), and a good deal of post-apocalyptic literature will feature at least one Pyrrhic victory.
