This article explores a little-studied subject of the civil war in the Astrakhan region. The purpose of the research was to study the combat operations of the 11th Army compounds, which made up the defense of the Volga River delta in the fall of 1919. The Volga River delta defense area, which included the western (Yashkul and Kizlyar directions) and eastern (Dzhambay direction) battle areas, was created on August 24, 1919. In the Dzhambay direction up to the middle of November 1919 the task of active defense of its area was set, which was replaced by the order to eliminate the enemy. In the Kizlyar direction the red troops were assigned the task of stopping the advance of the white troops with their subsequent destruction. In September-November 1919, all the tasks assigned to the command of the Volga River delta defense area were successfully accomplished.
