A quote from the The Brothers York by Thomas Penn:

“The fog lent the fighting a more desperate edge than usual. Hand-gunners and archers fired at the invisible enemy at point-blank range. Barely able to see in front of them, the combatants’ fear and disorientation were total: the fighting, as one participant put it, was ‘the more cruel and mortal’. Intensifying the chaos was the armies’ skewed alignment. On the Yorkist left, where Hastings’ men faced the earl of Oxford’s much bigger force, the imbalance was driven home. Oxford’s advancing troops swung round and piled into Hastings’ exposed lines, which, after a fierce fight, buckled and broke. Their blood up, Oxford’s men chased Hastings’ fleeing troops back down the road towards London.”

I was in Barnet on Saturday for a football match between Barnet and Woking but the memorial commemorating the battle is a bit of a haul.
