[12] Algernon Sidney (1622-1683) was the son of the second Earl of Leicester, and commanded a troop in the regiment raised by his father, when he was Lord-Lieutenant in Ireland, to put down the Irish rebellion of 1641. He afterwards came over to England, joined the Parliamentary forces, and was wounded at Marston Moor. He continued serving in various capacities, returning for a time to Ireland with his brother, Lord Lisle, who was Lord-Lieutenant. He was appointed one of the commissioners to try Charles I., but took no part in the trial. He was ejected from Parliament in 1653, and adopted a position of hostility to Cromwell. He remained abroad after the Restoration, though not excepted from the Act of Indemnity, and lived a philosophic life at Rome and elsewhere. He tried to promote a rising against Charles in Holland in 1665, and opened negotiations with Louis XIV. during the French war. He returned to England in 1677 to settle his private affairs, and stayed on making friends with the leaders of the Opposition, and vainly trying to obtain a seat in the House of Commons. He quarrelled with Shaftesbury, who denounced him as a French pensioner (which he probably was), and seems to have had no connection with his plots. He was arrested on 27th June, tried by Jeffreys on 7th November, condemned, and executed on 7th December 1683. [13] John Hampden (1656-1696) was the second son of Richard Hampden. After travelling abroad in his youth he became the intimate friend of the leaders of the Opposition on his return to England in 1682. He was arrested with them and tried in 1684, when he was imprisoned on failing to pay an exorbitant fine. After Monmouth's rising he was tried again for high treason. As Lord Grey was produced as a second witness against him, Lord Howard, who had testified before, being the first, he pleaded guilty, implicating Russell and others by his confession. He was pardoned, and lived to sit in Parliament after the Revolution; but falling into obscurity failed to be elected for his native county in 1696, and committed suicide.
