Vaga River front
Established along the Vaga River, a tributary of Northern Dvina, it was the southernmost line of advance of the Allied in the North Russia Campaign. Initially its purpose was to outflank the retreating Red Army, but when the tide turned it was vital to secure the Allied right flank on the Northern Dvina front.
