During the past week, Ukraine has inflicted a major operational blow against the Russian military, recapturing a swath of territory in eastern Ukraine including the city of Izyum in its most significant military success since the Battle of Kyiv in March, according to the Institute for the Study of War (ISW). In a first since the war began, Russia acknowledged its defeat in the region.
Ukraine’s counteroffensive, which began on September 6, took the Kremlin by surprise, both in terms of speed and the dynamism of advances with large pockets in Kharkiv oblast being reclaimed. According to the British defence ministry, in recent days, Ukrainian forces have captured territory at least twice the size of London.
