I want to know the answer to the following question:
When did Louis march into the city unopposed and proclaimed its annexation?
All the background I'm provided with is that "Louis' advisors believed that, as long as Strasbourg remained independent, it would endanger the King's newly annexed territories in Alsace, and, that to defend these large rural lands effectively, a garrison had to be placed in towns such as Strasbourg.". Is that enough to answer the question?
