I want to know the answer to the following question:
What battle began when two armies collided in the town of Froschwiller?
All the background I'm provided with is that "Having lost any hope for victory and facing a massacre, the French army disengaged and retreated in a westerly direction towards Bitche and Saverne, hoping to join French forces on the other side of the Vosges mountains.". Is that enough to answer the question?
