SANDWICH, EDWARD MONTAGU or MOUN TAGU, 1ST EARL OF (1625-1672), English admiral, born on July 27, 1625, was a son of Sir Sidney Montagu (d. 1644) of Hinchinbrook, who was a brother of Henry Montagu, ist earl of Manchester, and of Edward Montagu, 1st Lord Montagu of Boughton. He joined the parliamentary party at the outbreak of the Civil War. In 1643 he raised a regiment, with which he fought at Marston Moor, Naseby and at the siege of Bristol. Though one of Cromwell's intimate friends, he took little part in public affairs until 1653, when he was appointed a member of the council of state. In 1656 he was made a general-at-sea, his colleague being Robert Blake. Having taken some part in the operations against Dunkirk in 1657, he was chosen a member of Cromwell's House of Lords, and in 1659 he was sent by Richard Cromwell with a fleet to arrange a peace between Sweden and Denmark. After the fall of Richard he resigned his command and assisted in the restoration of Charles II. Again general-at-sea early in 166o, Montagu carried the fleet over to the side of the exiled king, and was entrusted with the duty of fetching Charles from Holland. He was then made a knight of the Garter, and in July 1660 was created earl of Sandwich.
During the war with the Dutch in 1664-1665 Sandwich com manded a squadron under the duke of York and distinguished himself in the battle off Lowestoft on the 3rd of June 1665. When
the duke retired later in the same year he became commander-in chief. Trouble arose over certain valuable Dutch prizes which he had taken, and Sandwich was dismissed from his command, but as a solatium was sent to Madrid as ambassador extraordinary. He arranged a treaty with Spain, and in 1670 was appointed presi dent of the council of trade and plantations. When the war with the Dutch was renewed in 1672 Sandwich again commanded a squadron under the duke of York, and during the fight in South wold Bay on May 28, 1672, his ship, the "Royal George," after having taken a conspicuous part in the action, was set on fire and was blown up. The earl's body was found some days later and was buried in Westminster Abbey.
Lord Sandwich claimed to have a certain knowledge of science, and his translation of a Spanish work on the Art of Metals appeared in 1674. Many of his letters and papers are in the British Museum, the Bodleian Library at Oxford, and in the possession of the present earl of Sandwich. He is mentioned very frequently in the Diary of his kinsman, Samuel Pepys. See also J. Charnock, Biographia Navalis, vol. i. (1794) ; John Campbell, Lives of the British Admirals, vol. ii.
