In Galicia a combined Austro-Hungarian and German force is attacking the Russians at Przemysl. After taking some of the outlying forts, the Austro-Hungarians now push into the town itself. The Russians still hold forts on the right bank of the river, but with the town back in Austro-Hungarian hands it will not be long before they fall.
The Russians were only able to capture Przemysl after a siege of four months. How has it been recaptured so quickly? The heavy artillery of the Austro-Hungarians is like nothing the Russians have themselves. It has been able to pummel the Russians into submission or else obliterate them. Also, the Gorlice-Tarnów offensive has the Russians in retreat everywhere; they are not committing major forces to the defence of Przemysl lest they be cut off by the enemy’s advance. So the Austro-Hungarians win back their city relatively easily, but by riding the Germans’ coat-tails.
