Mountain Warfare In The Northern Caucasus: Germans Pressed Northward -- Soviet mountain Armies in the wild land of the northern Caucasus are keeping up pressure on the enemy, driving them slowly and relentlessly Northwards between Nalchik and Mozdoe. The German armies of the Caucasus are thus caught between the inevitable pincers, the other claw of which, south west of Stalingrad, is driving forward rapidly in a series on sweeping successes.
