I'm trying to learn about this battle but it is a little tricky. Here's what I think I know(please correct me if I'm wrong).

Liege knew they were going to be attacked so they destroyed most but not all of their bridges. However, Germans made it into the city via some of these bridges on some date(if you know please help). Enrich von Ludendorff rode to the citadel, alone because he thought it had surrendered, but found that it was still occupied. Despite this, Ludendorff managed to get them to believe they were outnumbered, a bluff since he was alone. It works and he gains control of Liege and later uses massive Big Bertha artillery to destroy the forts and secure the route through Belgium for Germany.

My questions are: How much fighting took place inside Liege? Was it all contained outside of Liege or was their continuous fighting inside the city until it was captured?

Did Ludendorff actually capture the city alone or was it an exaggeration?

Did the city fall in two days after the siege began?

What did the forts do when Liege was occupied. I know they kept fighting until the 16th but did they make attempts to recapture the city?

Sorry if this is a lot of questions but I am trying to write a story and a lot of this information will help me piece it together. Also, I know some of my information might be inaccurate and I really appreciate corrections. Lastly, some of these questions might not have true answers and I understand that.

Thanks
