The most recent major Russian setback was the loss of the city of Kherson, from which they retreated in mid-November. This followed the territorial losses in the northern withdrawal in April and in Kharkiv in September.
Since then, Russia has made some modest gains in Donetsk over the winter, with attritional fighting centred on Bakhmut. Officials expect Russia to step up offensive efforts in the coming weeks.
As of Sunday 19 February, Russia controlled just over 40,600 sq miles in Ukraine, about 17% of Ukraine’s total landmass and roughly equivalent to the size of Iceland.
Territory estimates are based on an analysis of the daily control files from the Institute for the Study of War (ISW). These assess, on a daily basis, the extent of the land controlled or contested by Russian forces. Areas marked “Russian operations” on the map refer to areas that the ISW assesses Russian forces have operated in or launched attacks against but do not control. Areas marked “Ukraine regained control” on the map refer to areas that the ISW assesses Ukrainian forces have liberated but are still actively contested to some degree. In the last chart, other regions include Zhytomyr, Mykolaiv, Sevastopol, Dnipropetrovsk and Kyiv city.
