Peninsula in the Ukraine between the Sea of Azov and Black Sea (6)
I believe the answer is:
crimea
(Other definitions for crimea that I've seen before include "Ukrainian peninsula, scene of war" , "Peninsula in today's Ukraine, site of an 1853-6 war" , "Peninsula in Ukraine where the Light Brigade charged" , "A crime committed here on the northern coast of the Black Sea?" , "Disputed Black Sea peninsula" .)
