The latter, believing that Edward's line was facing his, kept up a heavy cannonade all night upon where he supposed Edward's left to be--a cannonade which was thus entirely futile.
In the morning (April 14th) a heavy mist covered the country and prevented either force from seeing the other's dispositions.

Warwick took the command of his left wing, having with him the Duke of Exeter.
Somerset was in command of his centre, and Montague and Oxford of his right.
Edward placed himself in the centre of his array, the Duke of Gloucester commanded on his right, and Lord Hastings on his left.
Desirous, from his inferiority in artillery, to fight out the battle hand to hand, Edward, at six o'clock in the morning, ordered his trumpets to blow, and, after firing a few shots, advanced through the mist to attack the enemy.

His misconception as to Warwick's position, which had saved his troops from the effects of the cannonade during the night, was now disadvantageous to him, for the Earl's right so greatly outflanked his left that when they came into contact Hastings found himself nearly surrounded by a vastly superior force.

His wing fought valiantly, but was at length broken by Oxford's superior numbers, and driven out of the field.

The mist prevented the rest of the armies from knowing what had happened on the king's left.
