The Russian army wasn’t nearly as experienced and well-trained as its German foe, and that led to some critical mistakes.

When the Germans learned that the Russians were invading East Prussia, they ordered Prittwitz to attack the northern Russian 1st Army at what became known as the Battle of Gumbinnen.
