On 12 October 1999, the Russian forces crossed the Terek and began a two-pronged advance on the capital Grozny to the south. Hoping to avoid the significant casualties that plagued the first Chechen War, the Russians advanced slowly and in force, making extensive use of artillery and air power in an attempt to soften Chechen defenses.
