Quatre Bras
During the Waterloo campaign de la Bédoyère, now promoted to "General de Brigade" and an aide-de-camp of the Emperor, was probably the officer sent with a message to d'Erlon's I Corps, then marching west to join Ney at Quatre Bras, to turn east to support the Emperor at Ligny. Ney was furious when he learned the corps was marching away from his battle and sent another order for it to return immediately to Quatre-Bras. As a result of these orders and counter-orders, d'Erlon's 20,000 men, which could have sealed the fate of the Anglo-Dutch at Quatre-Bras or the Prussians at Ligny, spent the entire day marching back and forth without firing a shot.
