Kadikoi (Crimean Tatar: Qadıköy, Russian: Кадыкой) in the 19th century was a village on the Crimean peninsula, in Ukraine, about one mile north of Balaklava.
Currently it's merged into Balaklava city, and is known as microdistrict Kadykovka.
The British Army built a stationary engine on a hillside near the village, to up haul trains carrying men and materiel.
Another hill, slightly to the north and east of Kadikoi, was defended by six companies of the 93rd (Highland) Regiment (the Sutherland Highlanders, around 600 soldiers), a Turkish battalion (around 1,000 soldiers), and a six-gun battery of field artillery.
The hill was attacked by a large force of Russian cavalry on 25 October 1854, but repulsed by the British "Thin Red Line".
