Zacharie Jacqnes Theodore Allemand, count, a French vice admiral, born at Port Louis (island of Mauritius) in 1762, died at Toulon, March 2, 1826. He entered the navy at the age of 12, was one of the first chevaliers of the legion of honor, and was soon after its formation raised to the rank of officer. In various cruises he inflicted immense losses upon English commerce. In 1809 he commanded the squadrons of Brest, Toulon, and Rochefort, in the capacity of vice admiral. The fleet was anchored in the Basque roads (between the islands of Aix and Oleron), when on April 11 Lord Cochrane attacked it with 50 fire ships and several infernal machines invented by Col. Congreve. Allemand saved all but four of his vessels, and the success of the English was very slight, compared to the immense cost of the expedition.
