What are some adjectives that describe victory?

"Victory" was traditionally applied to warfare:

Pyrhhic victory = a victory that carried such a devastating cost that another one like it would surely lead to defeat.

campaign victory = strategic victory = an overall victory in a large scale effort of significant duration.

tactical victory = a victory a particular implemented set of actual means that were used to gain an objective

(an objective is only a part of the overall strategy).

The above could be used in non-warfare settings.

Obviously, many other adjectives could be used: heroic, overwhelming, thrilling, tremendous, decisive, hollow, and many more.
