@ Dave....Did you see the Museum at the Monument? The Monument went through refurbishing and all that prior to 2013 for its 100th anniversary. I last saw it a couple of years before 2013.
I thought the Museum itself in its historical presentation of this gigantic battle until that point in time in 1813, ie armies of 4 nations against Napoleon , was not as comprehensive and balanced (ausgewogen) as I had expected. Maybe that was unrealistic on my part.
That painting depicting the meeting of the 3 victorious monarchs, the Emperor of Austria, the Tsar of Russia and the King of Prussia after the battle, is also in Berlin and Vienna , (the German History Museum on Unter den Linden, and the Heeresgeschichtliches Museum (Army Museum). Leipzig is the third place I've seen that painting.
Good that you made it out there !
