The Abkhaz military defeat was met with a hostile response by the self-styled Confederation of Mountain Peoples of the Caucasus, an umbrella group uniting a number of movements in the North Caucasus, including elements of Circassians, Abazins, Chechens, Cossacks, Ossetians and hundreds of volunteer paramilitaries and mercenaries from Russia, including the then-little-known Shamil Basayev, later a leader of the anti-Moscow Chechen secessionists. They sided with the Abkhaz separatists to fight against the Georgian government. In the case of Basayev, it has been suggested that when he and the members of his battalion came to Abkhazia, they received training by the Russian Army (though others dispute this), presenting another possible motive. In September, the Abkhaz and Russian paramilitaries mounted a major offensive against Gagra after breaking a cease-fire, which drove the Georgian forces out of large swathes of the republic. Shevardnadze's government accused Russia of giving covert military support to the rebels with the aim of "detaching from Georgia its native territory and the Georgia-Russian frontier land". 1992 ended with the rebels in control of much of Abkhazia northwest of Sukhumi.
