Right from history there have been crisis going on between Russia and Chechnya. Russia wants Chechnya to be its integral part, but people of Chechnya oppose it. The conflict over the region now known as Chechnya is since the mid-18th century.
The rising tension between the two eventually resulted in war in 1994, which was proved to be the badly organized mission by Russian troops. Chechnya's president Dzhokhar Dudayev during that period refused to compromise on the Kremlin line. This made Russian troops; felt that the part of their land was invaded which made them more furious.
Initially Moscow tried the tactics of getting the support of local people by providing them funds to invoke people of Chechnya against their President Dudayev. They also gathered the support of some of the forces, which helped Russian to set a secret attack on Grozny on 26 November 1994. Lack of proper planning for the attack made Russians to pay badly for it. The Chechen forces managed to face the sudden attack with courage and forced the Russian forces to retreat the attack. The Chechens captured around 20 Russian troops.
On 29 November, President Boris Yeltsin gave warning to Chechnya to disarm and surrender. The victory of the Chechens over Russian forces boosted them to oppose Russia’s ultimatum and denied to accept it. Russian forces then attacked on December first with massive aerial bombardments. The civilians were also targeted. This hardly proved any harm to Chechens who took the underground shelter.
On 11 December 1994, President Yeltsin increased the intensity of campaign and sent in the thousands of troops. Mean while President Dudayev declared war and forecasted that Russia would meet fierce resistance. Chechen Foreign Minister Shamsedin Yusef made a bold statement that they cannot kill every Chechen, there are one million of us and every one of us will fight.
Just after two days Russian forces entered Chechnya there was a battle with explosions all over the places. Chechens had limited supply of artillery and weapons so they decided to make the attack that would prove more effective. Armed with rocket-propelled grenade launchers they operated in small guerrilla units. They made for their lack in power and training by improvisation. They moved entire villages to prevent the passage of tanks.
Both the sides were exhausted and situation aroused such that both felt they should opt for peace talks. But none came forward with the peace proposal. The Russian military made heavy bombardments and hundreds of tanks entered the capital Gronzy. This massive onslaught against the capital began on New Year's Eve 1994.
Guerilla technique: This did not deter Chechen. They again used their tactic, which went quite successfully for them. Small groups were formed and they attacked the leading tanks, which passed through narrow passages with grenades. This caused obstruction for the following tanks, which made those Russian soldiers easy victims of Chechen forces.
In another incident were Russian soldiers tried to take control of the railway station resulted in slaughter of hundreds of Russian soldiers. At least 2,000 Russian soldiers were killed in the first days of the battle. Angered Russian army bombarded the places at their will. They were heavily criticized for that in media. By day three the Chechen leaders declared that they won the battle. By 3 January Russian forces began to withdraw.
