Much has been written about the battle and its location over the centuries. Recent research suggests that the traditional view of the battlefield may not be quite correct. Nora Day has proposed that the Yorkists approached from the east, rather than the south. Her article is an excellent read and makes a good argument.
For this project I will be sticking to the more established view of the battlefield. I will try the battle again later using Nora's ideas, as it will make for an interesting action when deployments are so different.
