French Marshal Ney, who was a big factor in the french defeat at Waterloo.
Napoleon left the battle for a few hours because he was feeling unwell. He gave the command to Ney.
A few Brittish bataljons were realigning on the hill where the coalition troops were standing. Ney thought that the coalition was withdrawing & sent all the French cavalry upon the hillside without any artillery or infantry backup. Not only that but there was only room for 2 or 3 cavalry units to manoever on the battlefield, but Ney decided to attack with all his cavalry troops. This goes on & on...but you get the picture.
Suffice to say that Napoleon must have said upon his return to the battlefield: "What the hell!!"
(i just saw the documentary series "Battlefield Detectives" episode: Waterloo)
Hmmmmm debateable, let me quickly outline why.
1) Ney had no choice, the bulk of his infantry were busy or being refused to him, to keep the allies from attacking him, he needed to pin their forces, hence the cavalry attacks. You're wrong to imply he had a choice, his only available, no engaged corps were Lobau (destined to try and hold the Prussians) and the Guard. Put simply he could not conjour infantry out of thin air, he needed time to gather such a force.
2) Ney was an experienced (if a little hot-headed), professional commander of decades of army experience. He was a good general when kept in check, the thing is though, not even Ney was THAT stupid. I'm pretty sure even Ney could tell apart a British withdrawl from a realignment, he'd fought British troops before, he'd know their tenacity more than most on the field that day. Also he launched over a dozen attacks up the slopes, nobody of Ney's character and standing would deliberately do this thinking they would retreat. Once or twice, yes, 4 times perhaps, but no way 12+ times, just not going to happen. Also ney had a decent past reputation, to call him incompetent based on such a single engagement is wrong IMO.
3) The cavalry attacks lasted over 4 hours, Napoleon is known to have released the Cuirassiers at least, he knew of the attacks, and was not ill for the entire period. 12+ attacks, 4 hours, pleanty of time to order a halt should Napoleon strictly disagree with such a plan.
Above that Napoleon's plan was abysmal, his control of the battle when well was pathetic, and his command of the army overall lacked cohesion and common sense after Ligny/Quatre Bras.
