To be fair to Ney he was a Cavalry commander put in charge of a whole army corps. I've read that he was so carried away with his cavalry charge that he forgot that his infantry would not move up behind unless he ordered it.
With the result that the British infantry were forced into square, with the gunners inside, but no one came up behind the French cavalry to capture the British guns, turn them on the British squares, or engage the squares with musket fire. Had they done so...well, as the Iron Duke himself said, it was a close run thing.
