February On 25 February, due to a lack of communications with the main invasion command, a convoy of
OMON and
SOBR units from
Kemerovo Oblast accidentally separated from the invasion forces and ended up charging at Kyiv by themselves. The convoy was ambushed at a bridge over the
Irpin River, and the unarmored and under-equipped units were completely destroyed. Reportedly, of the 80 soldiers in the convoy, only 3 wounded men survived. On 27 February, Ukrainian forces reported that
Russian Ground Forces had
advanced into Bucha, breaking through the city and advancing towards Irpin. A tank battle ensued inside the city, while Ukrainian infantry engaged Russian paratroopers. The Ukrainian forces used rockets, artillery, and airstrikes to halt the Russian advance, and destroyed a bridge connecting Bucha and Irpin. On 28 February 2022, Ukrainian official
Oleksiy Arestovych stated that Ukrainian forces attacked Russian forces on
Highway M06 in the morning and that more than 200 Russian vehicles were destroyed or damaged by the afternoon.
March 1–5 March 2022 On 2 March 2022, two Russian
Sukhoi Su-25s conducted airstrikes in Irpin. Two missiles struck a residential building, killing a child and injuring a woman. One of the Su-25s was shot down by Ukrainian forces. The jet was identified to be part of the Russian
18th Guards Assault Aviation Regiment. Ukrainian military officials reported that Russian forces had begun to lose momentum, taking significant casualties and being stopped at "unfavorable borders." On 3 March 2022, the
Kyiv Oblast State Administration announced that the Ukrainian government was sending
humanitarian aid to Bucha and Irpin, as well as announcing evacuations in both cities. More than 1,500 women and children were reported to have evacuated by train, while 250 were evacuated by bus. However, Ukrainian officials reported that the evacuations were complicated as some railway tracks had been destroyed during fighting.
Valerii Zaluzhnyi, the
Commander-in-Chief of the Armed Forces of Ukraine, announced that a Russian
Sukhoi Su-30 fighter jet was shot down over Irpin by Ukrainian air defenses on 3 March. On 5 March 2022, Ukrainian forces began to evacuate civilians from Irpin towards Kyiv on foot, though a destroyed bridge complicated efforts.
6–10 March 2022 On 6 March 2022, Russian forces captured part of Irpin. In the morning,
Oleksiy Kuleba, the city's Ukrainian military commander, stated that many evacuation routes out of the city were unsafe. According to
Human Rights Watch, the Russian shelling may have violated their obligations under international humanitarian law. The organization also stated that
Ukraine similarly had an obligation to prevent civilian casualties by not operating military actions in civilian areas. Ukrainian soldier
Pavlo Lee, an actor who had joined the
Territorial Defense Forces, was later killed by Russian shelling. On 8 March, Markushyn, who was commanding part of the Ukrainian forces in the city, stated that Russian forces demanded him to surrender the city, which he rejected, saying, "Irpin can't be bought, Irpin fights." On 9 March 2022, Russian troops were seen patrolling streets in Irpin. Ukrainian forces then conducted a large-scale evacuation across
Kyiv Oblast, including in Irpin. Up to 20,000 civilians were evacuated in Kyiv Oblast. Later, the Kyiv Oblast State Administration stated that fighting in Irpin continued during the night. ==Aftermath==
