King Charles having struck a deal with the Scots for an army, a Covenanter army roams the north English countryside. At the farming village of Heawold, the Scots try to hit the Parliamentarian army from two sides.
This was a messy battle-game. Because the Scots placed infantry on thier extreme flanks and cavalry in the middle, the Parliament forces were able to entirely rout the Scot cavalry quickly, because it simply took a long time for the flanking infantry to get towards the middle again.
The Scots infantry also took rather a lot of casualties closing in on the Parliament lines, and the whole thing looked a bit like a catastrophe for the Scots for a second. But then casualties on the Parliament army, with some selective last-ditch attacks by the Scots managed to force a tie.
