Fighting in Crimea was the third and final period of the war. Many soldiers of the White Army had gathered in Crimea. They had made their position very secure and strong. The Red Army continued to fight with them. When the Polish-Soviet War ended in Polish independence, more soldiers of the Red Army could reinforce their comrades in Crimea. This action defeated the White Army in November 1920. Fighting continued against nationalists in the Caucusus in the early 1920s.
