A harrowing vista stretches across Lyman, a strategic Ukrainian outpost on the Donbas region's northern edge, where years of relentless conflict have left an indelible scar. The 'fortress belt', a carefully crafted defensive line conceived by former President Petro Poroshenko in 2015, continues to thwart Russian advances with unyielding ferocity. Situated along the H-20 Kostyantynivka-Sloviansk main road, this critical stronghold spans approximately 30 miles north to south, comprising dense urban centres, industrial facilities, rivers, and rising terrain meticulously optimised for defence.
Despite being recaptured by Ukrainian forces in 2022 after a brief occupation by Russian troops, Lyman remains a focal point of intense fighting. The estimated 1,000 civilian residents eke out a precarious existence in cellars, devoid of basic amenities such as electricity, gas, and running water. A resident's poignant account highlights the catastrophic human toll: burying his 78-year-old mother due to shrapnel wounds, before embarking on a perilous 19-mile bicycle journey to safety, narrowly avoiding Russian drone fire.
The 'fortress belt' strategy hinges on Ukraine's unique geography, deliberately designed to exhaust and tie down Russian forces in eastern Ukraine. US think tanks like the Institute for the Study of War have underscored its strategic significance, warning that any attempt by Russia to capture it would incur significantly higher costs than previous campaigns in areas such as Bakhmut or Pokrovsk.
While some Donbas towns have fallen after gruelling sieges, recent reports signal a potential shift in momentum. Ukraine has recently reclaimed more territory than Russia for the first time since a 2023 counteroffensive. This reversal is attributed to increasingly effective Ukrainian drone attacks disrupting Russian supply lines to the Donbas and Crimea, as well as the tenacious defence of the 'fortress belt', which has drained considerable Russian resources and personnel.
The UK Government continues to condemn Russia's full-scale invasion of Ukraine in stark terms, reiterating its unwavering support for Ukraine's sovereignty and territorial integrity. The Foreign, Commonwealth & Development Office (FCDO) maintains a travel advisory against all trips to Ukraine due to the ongoing conflict, highlighting the extreme danger posed by active combat zones, missile strikes, and landmines. British nationals currently in Ukraine are advised to leave if it is safe to do so.
