1/ CONQUERING CRIMEA: PART 1

Since 2014, Crimea has been under Russian control. Ukraine, naturally, wants it back. But what does history show about the challenges of reconquering it? In a series of threads, I'll look at the lessons of past wars. Image
2/ Crimea's fascinating military history has been of interest to me for many years – I travelled there in the early 2000s to study its old battlefields, so some of this will be drawn from personal recollections and notes.
3/ Let's review Crimea's physical geography. It's a roughly diamond-shaped peninsula, about 320 km (200 mi) east to west by about 200 km (120 mi) north to south. It's mostly flat, apart from the Crimean (or Yayla) Mountains in the far south, which are up to 1,500m (5000 ft) high. Image
4/ Crimea borders the Black Sea on its west and south sides, and the Sea of Azov in the east. It's separated from Russia by the narrow Kerch Strait, across which Russia has built Europe's longest road and railway bridge to link it to the Russian mainland. Image
5/ The peninsula's climate is almost subtropical in the far south, but in the north and centre it's mostly arid, as a 2018 vegetation map highlights. Agriculture is dependent on an irrigation canal that runs from the Dnipro river in the Kherson region. Image
6/ Crimea is separated from the Ukrainian mainland by the Syvash, an area of salt lagoons and marshes which connects to the Sea of Azov via a narrow strait. It's also known as the Putrid or Rotten Sea for its pungent smell in the summer. (This image shows its *natural* colours.) Image
7/ The Syvash covers around 2,500 km² (965 mi²) and is up to 35 km (21 mi) wide, but is very shallow – only about 3 m (10 ft) deep at maximum. In some places and at the right times, it can be forded on foot. This is militarily significant, as we'll see.
8/ There are only three narrow places along the entire 100 km (62 mi) long northern flank of Crimea where the peninsula is connected to the Ukrainian mainland. This is why Crimea has often been called a "natural fortress", and makes it a difficult place to invade. Image
9/ From east to west, these places are the:

🔺 Arabat Spit
🔺 Chonhar Peninsula
🔺 Perekop Isthmus

All three of these have been used to invade Crimea, as we'll see in later threads in this series.
10/ For completeness we should mention the Kerch Strait as an entry point, as that's also of military importance. It's only 3.1 km (1.9 mi) wide at its narrowest. As well as the bridge, it's also crossed by ferries from Port Krym to the Chushka Spit on the Russian side. Image
11/ The Arabat Spit is a 112 km (70 mi) long sand spit – the longest in the world – which is only 270m (885 ft) wide at its narrowest point. It's low and exposed, relies on two bridges to connect it to the Ukrainian mainland and only connects to Crimea at its far southern end. ImageImage
12/ There is no proper road along the spit, only a sandy track, although Russia has suggested that it might create a new road to improve Crimea's connection to the Ukrainian mainland. Currently, though, it would be difficult for an army to pass along it. Image
13/ The Chonhar Peninsula is a narrow wedge of land extending south from the Ukrainian mainland into the Syvash, 20 km (12 mi) west of the Arabat Spit. Two road bridges and one railway bridge at its tip carry transport routes from Melitipol in Ukraine across the Syvash. ImageImage
14/ The Perekop Isthmus is the only unbridged link between Crimea and the Ukrainian mainland. It's only 9 km (5.5 mi) wide at its narrowest point and is of vital military and economic importance. The road, railway line and canal from Kherson to Crimea all come through here. Image
15/ There are a few small towns on the isthmus. Perekop (pictured below) itself is technically the oldest – a town has existed there since ancient Greek times. Armyansk was founded by Armenian merchants to trade with the Tatars who formerly ruled Crimea. Image
16/ To the south, Krasnoperekopsk, literally "Red Perekop", is a Soviet town built to house workers at a nearby bromine factory. The village of Ishun a short way further south is also of military significance for its location near three lakes – Krasne, Kyatske and Kyrleutske. Image
17/ While there have been battles on the Chonhar Peninsula and Arabat Spit, the Perekop Isthmus has been recognised for millennia as the gateway to Crimea. A line of fortifications has existed across the isthmus for at least 2,500 years, and has repeatedly been fought over. Image
18/ The ancient Greek name for Perekop, Taphros, means 'dug-out place'. It likely reflected the presence of a ditch across the isthmus at this point. The ditch is still there – it's clearly visible from space – and was fortified further between the 15th and 20th centuries. Image
19/ The fortification, known variously as the Perekop Wall, Turkish Wall or Tatar Ditch, is up to 45m (150 ft) wide and was originally up to 20m (65 ft) deep. It was anchored at the Perekop end by the now ruined Or-Kapi fortress, from which Perekop takes its name. ImageImage
20/ The fort was originally built by the Tatar Crimean Khanate in the 15th and 16th centuries to defend Crimea from the Mongol-descended Golden Horde. After the Horde's final defeat, the Tatars launched raids into the north to capture Slavs for the Ottoman slave trade. Image
21/ Not surprisingly, this caused conflict with the Cossacks who lived along the Dnipro. This brings us to the invasion of Crimea in 1675 by the Cossack Ivan Sirko, which will be the subject of my next thread in this series. /end Image

1/ Russian prisoners of war are being sent straight into to front line assault squads after being released from Ukrainian captivity. They are denied family reunions, interrogated by the FSB, and in some cases prosecuted. Many have attempted suicide. ⬇️
2/ Relatives of released Russian POWs have appealed to the Russian authorities to allow their loved ones to return home. Instead, they say, the men are being sent straight back into combat without even being able to see their families.
3/ In one video appeal published last month, the wife of captured Russian soldier Alexey Frolov says that he is awaiting his turn to be exchanged after a year in captivity. She asks the authorities to let him come home, rather than being sent straight back.

1/ Russian Railways is facing a worsening crisis. 300,000 disused railway wagons are congesting the network, entire freight trains have been abandoned for months, there are critical shortages of locomotives and workers, and a major drop in loading across the network. ⬇️ Image
2/ Russian Railways (RZD) has been in trouble for several years. It is facing an extremely severe shortage of staff, with some divisions of the company reportedly as much as 60% understaffed.
3/ RZD's problems have a huge impact on Russia's economy. It handles 47% of all cargo transport in Russia, and as much as 87% if pipelines are excluded. It's vital to the economy and the Russian military alike, as Russia's roads can't accomodate all the freight carried by rail.

1/ Economic distress in Russia is being reflected in a sharp increase from 1 July 2025 in tariffs for housing and municipal services – by up to 40% in some regions. This comes on top of steadily higher tariffs in 2023 and 2024, with an accelerating yearly level of price rises. ⬇️ Image
2/ ASTRA reports that tariffs in the regions will increase by between 8.6% in Amur to 21.1% in Perm. Moscow's tariffs will rise by 15%, the surrounding Moscow Region by 13.3% and St. Petersburg by 14.6%.
3/ Some local authorities can impose their own increases independently of the framework established by the central government. Thus Omsk is increasing its tariffs by 39.6%, and Izhevsk by 38%.

1/ Russians who have lost arms, legs or eyes are being sent into assaults in Ukraine, with little chance of survival. Despite severe injuries, they are either being denied a fitness assessment or are arbitrarily being rated fit. The men call themselves "meat on crutches". ⬇️ Image
2/ A Russian soldier has spoken of his experiences with a so-called 'cripple battalion' – a unit comprised of injured soldiers, which rather than recuperating or being allowed to heal or get treatment, is sent to the front line to take part in fresh assaults.
3/ 37-year-old Anton Savchenko from Tyumen – an ethnic Ukrainian with many relatives in Ukraine – volunteered to go to war in October 2024, saying that he "had to help". However, he soon regretted it, according to his relatives. Within less than a month, he had lost his left eye. Image

1/ Tens of gigabytes of secret data on Russia's strategic electronic warfare systems has been hacked by the pro-Ukrainian Russian Volunteer Corps (RDK). They say that Russia's EW shield is "not just fragile - it's full of holes" due to multiple flaws and vulnerabilities. ⬇️ Image
2/ Two weeks ago, the RDK announced that it had obtained a large quantity of data on Russia's EW systems, including technical specifications, diagrams, official correspondence, equipment setup methods, drawings, test reports, and functional information.
3/ RDK commander 'Fortuna' says that "We got more than just the external appearance. We see the internal logic, architecture, connections between nodes, we know who designed it, which companies supplied the units, which research institutes are responsible for the developments."

1/ Russian soldiers have now been serving for a longer time than any involuntarily mobilised Russian or Soviet troops since 1888, during the Tsarist period nearly 140 years ago. Not surprisingly, this has led many to complain of 'slavery'. ⬇️ Image
2/ The author of the 'Shelter No. 8' Telegram channel is a Russian soldier who joined the army in 2021. As he points out, the 3 years and 9 months he has served so far is approaching a new record for involuntary service since the end of the Tsarist period.
3/ "In Tsarist Russia, with the introduction of conscription, they served in the infantry:

- In 1881-1888 - 5 years.
- In 1888-1906 - 4 years
- I am here with my 3 years and 9 months.
- From 1906 to 1918, they served in the infantry for 3 years.
