The Battle of Mortimer's Cross
The Yorkists and the Lancastrians faced off at Mortimer's Cross. By this time, 1461 AD, guns, though primitive, were used in battles.
The Yorkists were led by the young (18yrs) Edward of York.
As dawn broke, three suns were seen to be rising. The appearance of this phenomenon so soon before the battle frightened his troops, but Edward convinced them that it represented the Holy Trinity and that therefore God was on their side. He later took it as his emblem, the "Sun in splendour"
He later became King Edward
