Russian troops have pushed Kyiv’s offensive backwards. Experts have questioned the success of the offensive, with one calling it a “strategic catastrophe” given manpower shortages faced by Ukraine.These developments come at a time of heightened uncertainty with a second Donald Trump administration looming. The US president-elect has vowed to bring the war to a close when he takes office in January, with some fearing he could cut future military aid to Ukraine.Russia advances in eastern UkraineIn the first few months of the war the front line moved quickly, with Russia gaining ground quickly before being pushed back by a Ukrainian counteroffensive. But in 2023 neither side made any major gains – with the conflict largely sliding into a stalemate.But new ISW figures suggest the story in 2024 is more favourable for Russia. The ISW bases its analysis on confirmed social media footage and reports of troop movements.The ISW data shows Moscow’s forces have seized around 2,700 sq km of Ukrainian territory so far this year, compared with just 465 sq km in the whole of 2023, a near six-fold increase.Dr Marina Miron, a defence researcher at Kings College London, suggested to the BBC that there was a possibility the Ukrainian eastern front “might actually collapse” if Russia continued to advance at pace.More than 1000 sq km was taken between 1 September and 3 November, suggesting the push accelerated in recent months. Two areas bearing the brunt of these advances are Kupiansk in Kharkiv region, and Kurakhove, a stepping stone to the key logistical hub of Pokrovsk in Donetsk region.Kupiansk and areas to the east of the Oskil river were liberated in the Kharkiv offensive of 2022, but Russia has progressively retaken the latter area. In a recent intelligence update, the UK’s Ministry of Defence said Russian forces were trying to breach the north-eastern outskirts of the city.Footage posted on 13 November and verified by the BBC is consistent with this analysis. The video shows a convoy of Russian armour being repelled after making it to within 4km of the key bridge at Kupiansk, the last major road crossing in the area.While these reports do not necessarily translate to control of an area, it is indicative of how stretched Ukraine’s defensive line has become.Elsewhere, since retaking the city of Vuhledar in October – an elevated position which sits above key s …
