Russian invasion In the early hours of 24 February, a large Russian force, estimated by Ukrainian military expert Serhii Hrabskyi to be 35,000 men strong, invaded
Kherson Oblast from
Crimea. Fighting was soon reported in
Chonhar, on the border with Crimea, and residents of the town of
Chaplynka in southern Kherson Oblast observed
columns of tanks,
armored personnel carriers, and
multiple rocket launchers moving in the direction of
Nova Kakhovka. Around the same time, Russian forces disembarked from helicopters and took up positions around the
Antonivka Road Bridge and the village of
Antonivka. With both of the area's crossings of the
Dnieper River under Russian control, Ukraine's
59th Brigade of about 1,200 men was effectively surrounded outside of
Oleshky.

Mi-8 transport helicopter was observed preparing to land paratroopers in the area of the
Antonivka Railway Bridge. Around midnight, the tank battalion of the 59th Brigade, which had remained positioned at the bridge, was met with a massive Russian bombardment involving
fighter planes,
Ka-52 attack helicopters,
FAB-500 bombs,
mortars and
artillery. After an hour-long battle, the battalion was forced to withdraw to the village of , having suffered heavy casualties; according to commander Yevhen Palchenko, only one of the battalion's
companies had remained intact. However, the unit would soon be ordered back to the bridge in order to support units of Ukraine's
80th Brigade, which had begun pushing Russian forces back from the bridge. Fighting continued throughout the early hours of 25 February. Around 4:00a.m. on 25 February, part of the 192nd Battalion was sent to prevent a bridge over the
Inhulets River at
Darivka from being captured by Russian paratroopers. They observed a Russian column on the opposite site of the Inhulets, and withdrew shortly thereafter, having received information that a column of Russian tanks was crossing the Antonivka Road Bridge. The bridge was still defended by Ukrainian soldiers, one of whom told the reporters that the nearest Russian positions were about away. The Russians were stationed at the southern side of the bridge, near Oleshky, but were said to not be disturbing civilians, who freely drove from one side to the other in personal vehicles.
Russian encirclement of Kherson Ukrainian forces withdrew from the Antonivka Bridge to
Kherson International Airport in
Chornobaivka on 26 February. The same day, Russian forces began unexpectedly advancing on the airport, forcing the Ukrainian units stationed there to retreat towards Mykolaiv. According to a

Anton Herashchenko, published footage of a destroyed column of Russian military vehicles near
Radensk and Oleshky, just south of Kherson. A Russian Mi-24 was shot down in Sahy, Kherson. On the morning of 27 February, the
Russian Ministry of Defence stated that Russian forces had encircled Kherson and, according to Ukrainian officials, had captured a part of the city, including the airport. Later in the morning, the
Ukrainian Air Force allegedly conducted
a successful drone strike against Russian forces in the town of
Chornobaivka, just to the north of Kherson. By 28 February, the
Institute for the Study of War assessed that Russian troops had likely completely encircled Kherson. ==Battle==
