This timeline speculates how events would have turned out if Marshal Grouchy had arrived before Marshal Blucher at the battle of Waterloo. In the real battle, the Prussians led by Blucher arrived first and destroyed Napoleon's army. But what if Grouchy, who Napoleon entrusted with a third of his army arrived first. Some of the events in this timeline could be construed as slightly fantastic. Also, the flags are of real world countries as I don't know how to upload or make my own images.
