Burnet's _History of his Times_, as we have seen, may be regarded as a connecting link between history and _mémoires pour servir_. The age of Charles II. was favourable to this latter class of composition, which is, indeed, the form which the narrators of public transactions in which they themselves have borne a leading part, naturally fall. The period was still more fertile in the diary, which may be defined as the autobiographic memoir in a rudimentary stage. One writer of the day, Samuel Pepys, has placed himself for all time at the head of this class of composition, by an achievement little likely to be repeated. Among memoir-writers proper the most important is Edmund Ludlow, the Cato of the Commonwealth (1617-1692). Ludlow, the son of a Wiltshire knight of extreme political views, enlisted at the commencement of the Civil War in the bodyguard of the Earl of Essex, and afterwards highly distinguished himself by his obstinate, though unsuccessful defence of Wardour Castle, in his native county. He was made prisoner, exchanged, and took part in several encounters in the West of England. Elected member for Wiltshire, he sided with the more extreme party, and was one of the king's judges. He became a member of the Council of State, and at the beginning of 1651 was sent to Ireland as second in authority to Ireton, whom he assisted in completing the subjugation of the country, and subsequently filled the same position under Fleetwood. Bitterly opposed to Cromwell's Protectorate, he resigned his civil appointment, but contrived to retain his military position until 1655, when, coming over to England, he was arrested and imprisoned in Beaumaris Castle. When at length he was admitted to an audience of Cromwell, 'What,' asked the Protector, 'can you desire more than you have?' 'That which we fought for,' replied Ludlow, 'that the nation might be governed by its own consent'--words which recall Augereau's repartee to Napoleon on the re-establishment of Roman Catholicism in France. Ludlow was kept under surveillance until the death of Cromwell, when he became exceedingly active, and upon the abdication of Richard Cromwell was sent again to Ireland in a position of authority. Returning, he sought in vain to mediate between the Parliament and the army, and distinguished himself in the Convention Parliament by a vain protest against the Restoration. He fled the country to avoid the vengeance of the new government, and took refuge in Switzerland, where he composed his memoirs, and abode in comfortable circumstances, although occasionally molested by plots against his life or liberty, until his death in 1692. The Revolution of 1688 had brought him back to England for an instant, but the public feeling against regicides was still too strong, and, returning to his refuge at Vevay, he carved over his door: 'Omne solum forti patria quia Patris.'
