Grouchy (groo-she'), Emmanuel, Marquis de. A Marshal of France. Born in Paris in 1766. He served with distinction under Napoleon I. Received a marshal's baton in 1814, and in 1815 refused to march his corps from Wavre to the assistance of the emperor at Waterloo, alleging his having received no order from Napoleon to that effect. It is not certain whether he intended to betray the cause of Napoleon, but his culpable indecision certainly contributed to the disaster which befell the French arms. Exiled in the same year, he was restored to his rank and honors in 1830, and died in 1847.
