Battle of Waterloo 1815 (Nap.)

The Battle of Waterloo was fought on Sunday 18 June 1815 near the village of Waterloo in Belgium. Two large forces under Wellington and Field Marshal Gebhard von Blücher assembled close to the north eastern border of France. Napoleon attacked first in the hope of dividing and destroying them before they could join in a coordinated invasion of France with other members of the Coalition. Can you change the outcome for either force?
