I've been vaguely outlining the events of my story and, having decided on a conflict between a Northern and Southern nation, I've been trying to decide just how large the armies would be. I recall reading somewhere - possibly here? - that the average army would have about 10,000 men, with larger ones probably having about 20,000. Anything above that would be a little bit of an exaggeration because of how much food etc. you would have to provide them with. Of course, I could have several different armies made up of about 20,000 each, but the main cause for my concern is that at one point in the story two different armies join together and number 42,000 men. I thought that it was far too much so I lowered down to 32,000 but I'm still stuck on another detail. Mainly that one of the two armies is the larger, up in the 20,000's while the other is smaller - 6,000 or something like that. They end up trying to cross a river but are attacked by an enemy army. A section of the army has made it across completely, another is wading through the water and the bulk is waiting to cross. When they're attacked a lot of the men at the front flee from the Northmen and end up running into the water and they all begin getting pushed together. It becomes a rout. There's still about 24,000 men on the bank waiting to enter the water and, when they see they mayhem, they decide it would be too costly to keep trying to cross. Not only that but I think two of the commanders have decided they'll turn to the North and because they hold the majority in the force they abandon the men in the water. That leaves about 8,000 people that are milling about in the water. What I'd like help with is deciding: 1. How many men are killed in the battle; this includes being killed by the Northmen and being knocked down and drowned/crushed by their own men. 2. How many are wounded during the fight, and possibly how many die after the battle. 3. How many manage to escape the fight. I know I'm the writer and I am supposed to decide this but I need a little help in any case. I'd have all of them die but I've noticed that the number of people that are actually killed in battles is actually quite low and more are wounded or choose to flee. If you could point me towards a similar battle that happened that might help me plan things out.
