No problem. Lindybeige is great, has a lot of fantastic content on his channel, so if you're into military history, he's your guy for a lot of this more interesting stuff. One of my favorites of his is a video about "where in a formation of soldiers does a rout begin?" https://www.youtube.com/watch?v=1OsLESoAGg0&t=510s I like how he approaches it from each possible angle, taking into account many variables.
