I want to know the answer to the following question:
How many casualties did the Prussians suffer at Saarbrucken?
All the background I'm provided with is that "While the French hailed the invasion as the first step towards the Rhineland and later Berlin, General Le Bœuf and Napoleon III were receiving alarming reports from foreign news sources of Prussian and Bavarian armies massing to the southeast in addition to the forces to the north and northeast.". Is that enough to answer the question?
Answer: no
