I see, so you think it would have been slightly larger than it really is in the game, or something along the lines of - Bruma battle on console = roughly 15 soldiers, Bruma battle in lore = 15 soldiers (to the power of 10)?
I'm sure that if Bethesda could have made the battle bigger, they would have. After all, all of the cities in Cyrodiil sent part of their armies to go aid Bruma. Yet the combined total was maybe 15-20 people. And the Daedra came out in waves of 3 or 4 to reduce strain on the engine. I'm positive that if Bethesda could have, they would have had dozens of people fighting with dozens of Daedra.
