Sir John Leake, an English admiral, born at Rotherhithe, Surrey, in 1656, died in Greenwich, Aug. 1, 1720. He distinguished himself in the fight with Van Tromp in 1673, when he served on board the Royal Prince, commanded by his father, by conveying relief to the starving garrison of Londonderry, and thus compelling the enemy to raise the siege. In 1702, during the war of the Spanish succession, he was made commodore, and appointed to the command of a squadron, with which he rescued Newfoundland from the French. For these services he was made rear admiral, and soon after vice admiral of the blue and knighted. In 1705 he constrained the French and Spanish to abandon the siege of Gibraltar; in 1706 relieved Barcelona, and captured Cartagena; and subsequently reduced the Balearic isles and Sardinia, After the relief of Gibraltar and the reduction of Cartagena, he was made vice admiral of the white, and presented with £1,000 by the queen; in 1707 he was appointed commander-in-chief of the fleet, and in 1709 rear admiral of Great Britain and a lord of the admiralty; and on retiring from active service, in the reign of George I., a pension of £600 was settled on him by parliament.

He represented Rochester in parliament several years.
