I would recommend you look at our book list as we have many books on many subjects, the Napoleonic and a Revolutionary sections are made by myself.

Some good documentaries on battles are by British father and son historians/presenters Peter and Dan Snow - however their series was specifically 20th Century battles and their historical context.

Here is the episode on Stalingrad. https://www.youtube.com/watch?v=oNpdMHpfrfE I hope you can find some more on older battles and commanders, as your question implies.
