Russia is reportedly preparing massive defences to prevent a lightning offensive to retake the occupied peninsula.

4 min read

To paraphrase the words of , Volodymyr Zelensky, everything began with Crimea, and everything will end there as well. When Russia first occupied Crimea in 2014, it was a major win for Putin, who successfully called the west鈥檚 bluff by proceeding to annex the peninsula with minimal international opposition.

Now, as Ukrainian forces consider how to , the Russian high command needs to think about how to prevent the recapture of the one territory that they cannot afford to lose.

Ukraine watchers are reporting that  along the northern edge of Crimea, actively  to help fortify the area around the Isthmus of Perekop, the  connecting Crimea to the rest of Ukraine.

Russia has been continuously reinforcing the area since its initial occupation back in 2014, more recently redoubling defences each time . As a result, both the narrow land bridge and the adjoining coastline of the Syvash Bay are now . Taken together with rumours of  of any remaining civilians, it is fair to say Russia is gearing up for something to happen in the area.

Why Crimea matters

Zelensky has always maintained that the war in Ukraine . In his nightly address, in August 2022, he said:

Russia has turned our peninsula, which has always been and will be one of the best places in Europe, into one of the most dangerous places in Europe. Russia brought large-scale repression, environmental problems, economic hopelessness and war to Crimea.

Correspondingly, this has drawn harsh rhetoric from Moscow, most recently from former Russian president Dmitry Medvedev who warned that Moscow would use 鈥渁bsolutely any weapon鈥 if Ukraine attempted to retake the peninsula 鈥 which many take to mean nuclear weapons.

Crimea is incredibly significant at the strategic level. It is a base for Russia鈥檚 , and provides critical access to trade through ports such as Sevastopol. But in terms of the narrative of the conflict, Putin and his allies have woven Crimea into the , framing it as a . Losing the region would be humiliating and costly for the regime.

For years, the idea of Ukraine reclaiming Crimea has appeared more than remote. But Kyiv鈥檚 military successes at the back end of 2022 have since changed this perception, and the recapture of Kherson back in September has put .

So far the threat of a nuclear response has appeared to be a bluff, with Russia failing to follow through, despite a series of  on Russian military installations there. And Kyiv鈥檚 narrative of needing to liberate all territory occupied by Russia since 2014 is . A spring offensive to the south has been all but confirmed, with a stated objective of  Crimea from Russian support.

But the battle for Crimea itself is still a way off.  needs to be in place before any direct offensive can take place. Nevertheless, an operation that once seemed impossible is now being seriously considered by both sides.

The fight for Crimea

Should it come to a military operation, Crimea is not going to be an easy fight. Options such as an amphibious or airborne assault are too risky, given that Russia still has serviceable naval . A direct approach would see a massive Ukrainian offensive down the Isthmus of Perekop. This could result in Ukrainian forces being funnelled into the area Russia is currently reinforcing, which is far from ideal.

If there is a place to stop a Ukrainian land force, this would be where it happens. The isthmus is an ideal choke point, with little room to manoeuvre. This  is turning the area into a formidable position 鈥 the narrow space is ideal for .

An attacking land force would be at a major disadvantage, even if they possessed naval and air superiority, which unfortunately for Ukraine, . With the isthmus effectively defended, Crimea becomes an island. This type of challenge will require different skills and equipment to address, being unlike any of the operations it has conducted so far.

It is no coincidence that its name 鈥 Perekop 鈥 roughly translates to . The isthmus has been  down the centuries and history tells us it will be hard to retake with a direct assault.

By the time Ukraine launches its counter-offensive in the south, the reality on the ground should look different. Russia鈥檚 winter-spring offensives in the  and the invasion force has taken significant losses in months of heavy fighting in Bakhmut. Russian military morale is reported to be  with reports of friction between regular army and Wagner Group mercenaries.

The first aim of any Ukrainian southern offensive would be to isolate the peninsula from resupply completely. Despite , the one road link between Crimea and Russia, it has been shown be vulnerable and closing it again would mean Russia needing to resupply by sea or air, which is unsustainable for any length of time. If the peninsula can be cut off, the Russian presence in Crimea .

The fortifications reportedly being prepared in advance of a possible Ukrainian assault show that Moscow, at least, is taking this prospect seriously. But a great deal will depend on Kyiv receiving superior weaponry in sufficient quantities to launch an attack. One thing seems certain though 鈥 the outcome of the battle for Crimea will be a .
