By 1500, Lobau confirmed that the Prussians were only five miles away and would be in a position to attack in less than two hours. Napoleon was now on the clock. A Prussian appearance would destroy morale, so he quietly started the rumor that the troops to the east were Grouchy’s. This bit of “command disinformation” had to hold up until Grouchy did show up, or Ney broke Wellington’s weak point, his center, and La Haye Sainte was its key.
Around 1530, D’Erlon threw the full weight of his reformed corps at the tiny farm compound, but the French numbers worked against them and Major Baring’s troops held out. Again trying to make up for his previous failure, Ney had assembled 12,000 (one, two, plus three zeroes) French cavalry to support him once he struck the ridge. Ney was expecting D’Erlon to steamroll the farm. Meanwhile, the Grand Battery continued to pound the remainder of Wellington’s line, then completely exposed on the forward slope after the counterattack.
By 1600, the Grand Battery was inflicting serious damage on the Allied troops, so Wellington pulled everyone not engaged around La Haye Sainte back to the reverse slope. Cavalrymen in the best of times are an impatient lot, and the fiery Ney with thousands of his brothers were no exception. To the great mass of cavalrymen, it looked as if the Allies were retreating. A great cry went up, and unwilling to wait any further on D’Erlon, Ney ordered the charge. Napoleon was furious but could do nothing to stop the impetuous Ney. The cavalry surged forward and easily overran Wellington’s cannon. But as they crested the ridge they ran not into retreating columns, but dozens of hollow infantry squares.
The infantry square is a formation that provided all around protection against a cavalry attack and relies on simple animal instinct: a horse will not throw itself against a wall of sharp objects, in this case bayonets. All the cavalrymen could do was ride up or around and whack the bayonets with their sabres, or shoot the Allies with their carbines and pistols. The square is horribly vulnerable to cannon shot and infantry attack, but with D’Erlon occupied with the fight on the reverse slope, no square would be broken that day.
But that didn’t stop Ney from trying and he personally led many of the attacks. While rallying a group of cuirassiers, he yelled, “Come and see how a Marshal of France can die!” He had five horses shot out from underneath him but he survived. Still, Ney wouldn’t stop and the Allies were hard pressed. If La Haye Sainte or Hougamont fell, and that infantry came to Ney’s aid, the game was over.
Around 1730, Wellington, stuck in a square and oblivious to anything beyond it, kept looking at his watch and saying, “Give me night, or give me Blucher.”
