The 59th Army was formed on 15 November 1941 in the Siberian Military District in accordance with a Stavka order of 2 November. It included the 366th, 372nd, 374th, 376th, 378th and 382nd Rifle Divisions and the 78th and 87th Cavalry Divisions, as well as other smaller units. The army became part of Stavka reserve upon completion of formation and was transported westward by rail to the Arkhangelsk Military District. In early December, it helped construct the Cherepovets Fortified Area and improved the defensive line on the eastern shore of Lake Beloye and the Sheksna River. The line ran from the mouth of the Sheksna to the village of Myaksa.
