I want to know the answer to the following question:
What seige did these victories lead to?
All the background I'm provided with is that "A series of swift Prussian and German victories in eastern France, culminating in the Siege of Metz and the Battle of Sedan, saw the army of the Second Empire decisively defeated (Napoleon III had been captured at Sedan on 2 September).". Is that enough to answer the question?
Answer: yes
