Auguste Henri Marie Pieot Dampierre, marquis de, a French soldier, born in Paris, Aug. 19, 1756, died in battle near the forest of Vioogne, May 8,1793. He early entered the army, but Louis XVI. ridiculing his partiality for Frederick the Great and Prussian tactics, he resigned his commission. He became president of the department of Aube, and in 1791 aidede-camp of Rochambeau, and subsequently served under Biron as colonel of dragoons. He was raised to the rank of general, and at Valmy, Sept. 20,' 1792, commanded a division under Dumouriez. At Jemappes, Nov. 6,1792, he had the principal part in the brilliant victory over the Austrians, but was subsequently defeated at Maestricht, and shared in the defeat at Neerwinden, March 18, 1793. After the defection of Dumouriez Dampierre succeeded as commander-in-chief, and undertook the offensive against superior numbers of the enemy. He was repulsed on May 6, but renewed the action the following day in the forest of Vi-cogne, and received a fatal wound. The attack was repelled, but the French retired in good order.

The convention, which had been on the point of sending him to the guillotine, decreed public honors to his memory.
