A city ruined. In once quiet residential streets, two armies battle, driving people into cellars and basements with little food or water. No lights or heat. Dwindling medical supplies. Shells and bullets deliver cruel, random death to the young and old, men, women, and children. This is Mariupol, a Ukrainian city and early target of Russia's invasion of Ukraine. Bordering Russian-occupied territory, the coastal city seemed doomed to a defeat that would come within days, if not hours. Could Mariupol, and Ukraine, survive? As Russian rockets threatened the city, Ukrainians resisted, and with a heroic combination of sacrifice and bravery, the besieged city endured. But it all came at a steep cost.
