The First Chechen War, also known as the War in Chechnya, was a conflict between the Russian Federation and the Chechen Republic of Ichkeria, fought from December 1994 to August 1996. After the initial campaign of 1994–1995, culminating in the devastating Battle of Grozny, Russian federal forces attempted to seize control of the mountainous area of Chechnya but were set back by Chechen guerrilla warfare and raids on the flatlands in spite of Russia's overwhelming manpower, weaponry, and air support. The resulting widespread demoralization of federal forces, and the almost universal opposition of the Russian public to the conflict, led Boris Yeltsin's government to declare a ceasefire 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. Although there are no accurate figures for the number of Chechen militants killed, various estimates put the number at about 3,000 to over 15,000 deaths. Various figures estimate the number of civilian deaths 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.
