Hulin, Or Hullin, Pierre Augustin, count, a French general, born in Paris, Sept. 6, 1758, died Jan. 9, 1841. He enlisted in the army when scarcely 13 years old, entered the regiment of French guards, and was a sergeant when the revolution broke out. He sided with the people, distinguished himself by his valor and humanity at the taking of the Bastile, July 14, 1789, and was appointed captain in the national guards under Lafayette. During the reign of terror he was imprisoned, but was liberated after the fall of Robespierre. In 1796 he joined the army of Italy under Bonaparte, who appointed him adjutant general; he was governor of Milan in 1797-8, and was in Paris on the 18th Brumaire, when he supported his general. He followed Bonaparte in Italy during the campaign of Marengo; was made brigadier general in 1803; presided over the court martial which sentenced the duke d'Enghien to death, March 21, 1804; received the rank of general of division and the command of the first military division in 1807; and was the next year created count of the empire.

He held the command of Paris until the first restoration; and although, after the abdication of Napoleon, he had sent in his adhesion to the new government, he was dismissed by the Bourbons. He resumed his post during the hundred days, was arrested on the second restoration, and compelled to leave France, but was allowed to return in 1819. Under the title of Explications offertes aux homines impartiaux au sujet de la commission militaire institutee en l'an XII pour juger le due d'Enghien (Paris, 1823), he published a plain account of his part in that tragedy.
