6. The American-Canadian withdrawal continued throughout the winter of 1919
From the defeat at Shenkursk, American and Canadian forces withdrew to the vicinity of Vystavka, where defensive positions had been prepared and reinforced by other units of the American 339th Infantry Regiment. From January 27, when the Red Army made contact with the defenses, until March of that year, the Americans, Canadians, and White Army units manning the defenses during the bitter Russian winter repulsed numerous assaults by Red Army infantry, in fighting which was often fierce. The Red Army continuously added to its artillery strength, and the bombardment of the positions intensified throughout the campaign, but only a few outlying Allied positions were overrun.
In early March the decision was made by the British commander of the expedition in Arkhangelsk to abandon Vystavka and establish a new defensive line near Kitsa, about five miles further downriver. The Red Army elected not to pursue. The more than two month long assault on Vystavka was a major victory for the Red Army, and the long months of nearly constant bombardment combined with the bitter cold had seriously detracted from the morale of the American and Canadian troops. The Canadians never again engaged the Red Army during the Allied Intervention, though the Americans still had battles to fight against the Russians.
