On 6 August 1996, three days before Yeltsin was to be inaugurated for his second term as Russian president and when most of the Russian Army troops were moved south due to what was planned as their final offensive against remaining mountainous separatist strongholds, the Chechens launched another surprise attack on Grozny.
On 19 August, despite the presence of 50,000 to 200,000 Chechen civilians and thousands of federal servicemen in Grozny, the Russian commander Konstantin Pulikovsky gave an ultimatum for Chechen fighters to leave the city within 48 hours, or else it would be leveled in a massive aerial and artillery bombardment. He stated that federal forces would use strategic bombers (not used in Chechnya up to this point) and ballistic missiles. This announcement was followed by chaotic scenes of panic as civilians tried to flee before the army carried out its threat, with parts of the city ablaze and falling shells scattering refugee columns.
Within five years, the marriage was in trouble due to the couple's incompatibility and near 13-year age difference. Charles resumed his relationship with his former girlfriend Camilla Parker Bowles, and Diana began one with Major James Hewitt, the family's former riding instructor. In December 1992, British Prime Minister John Major announced the couple's formal separation in Parliament. Charles and Diana divorced on 28 August 1996.
