Russia had expected to be victorious long before now. Its initial plan envisaged ground assaults across Ukraine in the first ten days and a rapid capitulation thereafter. But Kyiv did not fall – and Ukraine’s president, Volodymyr Zelensky, refused to leave the capital, saying, “I need ammunition, not a ride,” as he rallied Ukrainians. Russian troops had withdrawn from northern Ukraine by April.

Moscow pursued a more limited operation in the second phase over the spring and early summer, expanding its occupation of part of southern Ukraine and seizing all of the Luhansk region and parts of neighbouring Donetsk in the east.

But the third phase from August through November has involved a Ukrainian fightback in the north-east and south, regaining most of the territory gained by the Russian military in the first few months.

A Putin victory is now hard to envisage. His “annexation” of four Ukrainian regions is in tatters. Now the question is how far and how fast Ukraine can regain the territory occupied in 2022, and put pressure on areas held by Russian proxies since 2014.

What then for the fourth phase of the war which will play out over winter?

The battlefield

With the liberation of Kherson city, Ukrainian forces hold all areas west of the Dnipro River. The retreating Russian forces are on the east bank, having blown up all major bridges to prevent Ukrainian pursuit. But there are gathering signs of another Ukrainian push. The first troops crossed the Dnipro and established a foothold in a village last week.

The Russians are moving civilians out of some settlements on the east bank, and have reportedly withdrawn some troops as well.

It remains unclear where they will establish their new defensive line. The Ukrainian pattern through the autumn has been to degrade Russian capabilities, through strikes on occupied Crimea as well as eastern Kherson, before advancing on the ground. The strikes have damaged or destroyed bases, warplanes, ammunition depots, bridges and logistics and supply positions.
