Ukraine in maps: Tracking the war with Russia

But they hit very strong Ukrainian resistance almost everywhere and faced serious logistical problems with poorly motivated Russian troops suffering shortages of food, water and ammunition.

Ukrainian forces were also quick to deploy Western supplied arms such as the Nlaw anti-tank system, which proved highly effective against the Russian advance.

By October 2022, the picture had changed dramatically and having failed to take Kyiv, Russia withdrew completely from the north. The following month, Ukrainian forces recaptured the southern city of Kherson.

Since then, the battle has mostly been in the east of Ukraine with Russian forces slowly gaining ground over many months, while losing at least 50,000 troops – and probably many more.
