The operation began on 11 December 1994 and, by 31 December, Russian forces were entering Grozny, the Chechen capital. The 131st Motor Rifle Brigade was ordered to make a swift push for the centre of the city, but was then virtually destroyed in Chechen ambushes. After finally seizing Grozny amid fierce resistance, Russian troops moved on to other Chechen strongholds. When Chechen militants took hostages in the Budyonnovsk hospital hostage crisis in Stavropol Kray in June 1995, peace looked possible for a time, but the fighting continued. Following this incident, the separatists were referred to as "insurgents" or "terrorists" within Russia.
