What was the bloodiest day in the history of the British army?

Prabably the decisive battle in the 15C Wars of the Roses between the houses of Lancaster and York was fought at Towton to the south of York and near Tadcaster.

No official records were kept but it is estimated atleast 20,000 men met their death on this bitterly cold dayin March.

Try and imagine then what the population ofBritain was in the 15C, it has been sudjested that the carnage at Towton was so great that everyone living in Britain then would have known or atleast lost somebody close to them in the battle.
