Ukrainian President Volodymyr Zelensky, (presumably with the advice of his U.S. and British military advisors), has also adopted a strategy of holding ground in Eastern Ukraine. Ukrainian forces immobilized themselves inside urban areas, and prepared defenses. As a result, Ukrainian forces turned urban centers into fortifications for what became “last stands.” Sensible withdrawals from cities like Mariupol that might have saved many of Ukraine’s best troops were forbidden. Russian forces responded by methodically isolating and crushing the defenders left with no possibility of either escape or rescue by other Ukrainian forces.
Moscow’s determination to destroy Ukrainian forces at the least cost to Russian lives prevailed. Ukrainian casualties were always heavier than reported from the moment Russian troops crossed into Eastern Ukraine, but now, thanks to the recent failure of Ukrainian counterattacks in the Kherson region, they've reached horrific levels that are impossible to conceal. Casualty rates have reached 20,000 killed or wounded a month.
The Russian command opted to withdraw its small force from the area that is roughly 1 percent of formerly Ukrainian territory currently under Russian control. However, the price for Kiev’s propaganda victory was high—depending on the source, an estimated 5,000 to 10,000 Ukrainian troops were killed or wounded in a flat, open area that Russian artillery, rockets, and air strikes turned into a killing field.
