It is remote, inhospitable, windswept and largely uninhabited, but it has been fought over for centuries. Legend has it that the rocky outcrop in the Black Sea was created by the sea god Poseidon as a home for the greatest of all Greek warriors: Achilles. And just like the demigod, the small, cross-shaped island has seen its share of wars. Today, the tiny piece of land is known as Snake Island (Zmiinyi Island), and on Monday Ukrainian forces raised the country’s flag there once again after seizing the island back from Russian occupiers, driven away after months of heavy bombardment.
