of Tsaritsyn (modern Volgograd) on the Volga to end the possibility of the Soviet Red Army entering the Don region, a demand that Denikin opposed. Krasnov so desperately wanted to secure Tsaritsyn that he even offered to have Don Cossacks temporarily serve under Denikin's command if he was willing to advance on Tsaritsyn, but Denikin had other plans. Viewing Krasnov as unreliable and untrustworthy, Denikin instead decided to launch the Second Kuban Campaign of June–November 1918, taking his army south to the territory of the Kuban Cossack Host to raise more men and to take on the Red North Caucasian Army before turning north towards Moscow. Moscow become the Soviet capital in March 1918 as Lenin had decided that Petrograd (modern St. Petersburg) was too exposed to the German Army, which had occupied what is now the Baltic states. Denikin viewed the Kuban Cossacks as more willing to help than Krasnov and his Don Cossacks, who tended to put their own interests first. General Vyacheslav Naumenko, the field ataman of the Kuban Host was known to be more willing to work with the White generals. Denikin also believed that he needed to liquidate the 70,000-strong Red North Caucasian Army first before advancing on Moscow, arguing that an advance on Moscow would be impossible with a threat to his rear. Denikin's decision to turn the Volunteer Army south to the Kuban rather than north to Moscow became one of the most controversial of the Russian Civil War - by not advancing north in 1918 Denikin missed his best chance of linking up with the White forces in Siberia under Admiral Alexander Kolchak, who were advancing west along the Trans-Siberian Railway in the direction of Moscow. In the second half of 1918 Krasnov advanced towards Povorino-Kamyshin-Tsaritsyn, intending to march on Moscow on his own, but was defeated. In the siege of Tsaritsyn in November–December 1918, Krasnov sent his Cossacks repeatedly to storm Tsaritsyn, only to see them cut down by Red machine-gun and artillery fire. Following his defeat at Tsaritsyn, Krasnov returned to the territory of the Don Cossack Host and refused all offers to co-ordinate with Denikin unless he was made Supreme Commander-in-Chief of the Whites first. After Germany's defeat (November 1918) in World War I, Krasnov set his sights on the Entente powers in his search for allies. Under the terms of the armistice of 11 November 1918 ending World
