I want to know the answer to the following question:
By nightfall a major component of the VII and VII Corps withdrew towards what Prussian position?
All the background I'm provided with is that "By 16:50, with the Prussian southern attacks in danger of breaking up, the Prussian 3rd Guards Infantry Brigade of the Second Army opened an attack against the French positions at St. Privat which were commanded by General Canrobert.". Is that enough to answer the question?
Answer: no
