After the initial campaign of 1994 and 1995 Russian federal forces attempted to seize control of the mountainous area of Chechnya but were set back by their guerrilla warfare and raids on the FLAT LANDS despite Russia's overwhelming manpower, weaponry, and air support. the Russian public to the conflict led Boris Yeltsin's government to declare a ceasefire with the Chechens in 1996 and sign a peace treaty a year later. The official figure for Russian military deaths is 5,500, while most estimates put the number between 3,500 and 7,500, or even as high as 14,000. the number of Chechen forces killed was about 3,000 to over 15,000 deaths. the number of civilian deaths is at between 30,000 and 100,000 killed and possibly over 200,000 injured, while more than 500,000 people were displaced by the conflict, which left cities and villages across the republic in ruins. The conflict led to a significant decrease of non-Chechen population due to violence and discrimination.
