From a New York Times story by Marc Santora and Andrew E. Kramer headlined “For Ukraine, So Much Unexpected Success, and Yet So Far to Go”:

KYIV, Ukraine — In forests, in fields and in fierce urban combat, the Ukrainian military has defied the odds, and all expectations, and forced Russia into multiple retreats over nine brutal, bloody months of war.

And yet despite its success, and even with tens of thousands of soldiers killed on each side, Ukraine by one measure is only halfway done: Its army has now reclaimed about 55 percent of the territory Russia occupied after invading in February.
