Reporters Without Borders protested Russian intimidation of the press in Pervomayskoye, its ban of medical assistance to civilians and its refusal to permit evacuation of the wounded. On the eighth night, despite Kulikov's assertion that three rings of security forces had surrounded the village, the Chechens broke out and escaped in the early morning of January 18, 1996. They took with them about 20 Russian police hostages and several dozen civilians; a number of wounded guerrillas were carried on stretchers by the hostages (who also carried ammunition), while about 20 fighters too seriously injured to be moved were left behind. Both sides suffered heavy losses. Chechen commander Turpal-Ali Atgeriyev said 17 of the 40 Chechen fighters leading the breakout died as they fought their way through Russian positions and across a minefield. According to Memorial, the Chechens killed nearly all of a blocking detachment from the Spetsnaz GRU 22nd Brigade, including the intelligence chief of the 58th Army. The middle part of the rebel column with the wounded and the hostages suffered 26 fatalities, according to leader Aydemir Abdullayev (an ethnic Avar); the rear guard was commanded by Suleiman Bustayev. After the skirmish the column crossed the border river through a gas pipeline and ran across the frozen steppe, trying to reach safety before dawn, and a number of Chechen fighters were killed by strafing attacks of Russian Mi-24 helicopters during the pursuit. However, only three or four hostages lost their lives, and some of them escaped in the chaos. A force of between 200 and 300 guerrillas arrived in the area from Chechnya, where rebel fighters grouped under the command of Maksud Ingulbayev (who was ordered by Dudayev). To aid the breakthrough they mounted a diversionary attack on the Russian lines from behind, briefly capturing a school building used by federal forces in the neighboring village of Sovetskoye (several kilometers from Pervomayskoye). The Chechen relief force, like Raduyev's detachment earlier, made its way undetected through Russian-patrolled areas of Chechnya and Dagestan; Russian officials later accused the residents of two nearby villages of collaboration with the rebels. Russian forces entered a destroyed village strewn with the corpses of Chechen fighters, Dagestani civilians and Russian troops. After the battle a Russian soldier unintentionally fired a cannon on his BMP-1 infantry fighting vehicle, hitting another armored vehicle which exploded and its fragments landed amongst the Alpha Group of the FSB, killing two commandos and injuring three.
