Capturing Mariupol was a key goal for Russia for a few reasons, but, most critically, a victory in Mariupol gives Russia access an unobstructed land bridge from the Crimean peninsula it illegally annexed from Ukraine in 2014 to the Donbas region in southeastern Ukraine, potentially enabling easier troop mobilization into the Donbas that has become the focus of Russia's invasion.Owned.
