From Chapter 4:
Whether the use of tobacco prevailed as generally among the Cavalier forces is less certain; but as King Charles hated the weed, courtiers may have frowned upon its use. One distinguished cavalier, however, either smoked his pipe, or proposed to do so, on a historic occasion. In Markham's "Life of the Great Lord Fairfax" there is a lively account of how the Duke, then Marquis, of Newcastle, with his brother Charles Cavendish, drove in a coach and six to the field of Marston Moor on the afternoon before the battle. His Grace was in a very bad humour. "He applied to Rupert," says Markham, "for orders as to the disposal of his own most noble person, and was told that there would be no battle that night, and that he had better get into his coach and go to sleep, which he accordingly did." But the decision as to battle or no battle did not rest with Prince Rupert. Cromwell attacked the royal army with the most disastrous results to the King's cause. His Grace of Newcastle woke up, left his coach, and fought bravely, being, according to his Duchess, the last to ride off the fatal field, leaving his coach and six behind him.

From Chapter 5:
Country gentlemen smoked just as much as town mechanics and tradesmen. In 1688 Hervey, afterwards Earl of Bristol, wrote to Mr. Thomas Cullum, of Hawsted Place, desiring "to be remembered by the witty smoakers of Hawsted." A later Cullum, Sir John, published in 1784 a "History and Antiquities of Hawsted," and in describing Hawsted Place, which was rebuilt about 1570, says that there was a small apartment called the smoking-room—"a name," he says, "it acquired probably soon after it was built; and which it retained with good reason, as long as it stood." I should like to know on what authority Sir John Cullum could have made the assertion that the room was called the smoking-room from so early a date as the end of the sixteenth century. No mention in print of a smoking-room has been found for the purposes of the Oxford Dictionary earlier than 1689. In Shadwell's "Bury Fair" of that date Lady Fantast says to her husband, Mr. Oldwit, who loves to tell of his early meetings with Ben Jonson and other literary heroes of a bygone day, "While all the Beau Monde, as my daughter says, are with us in the drawing-room, you have none but ill-bred, witless drunkards with you in your smoking-room." As Mr. Oldwit himself, in another scene of the same play, says to his friends, "We'll into my smoking-room and sport about a brimmer," there was probably some excuse for his wife's remark. These country smoking-rooms were known in later days as stone-parlours, the floor being flagged for safety's sake; and the "stone-parlour" in many a squire's house was the scene of much conviviality, including, no doubt, abundant smoking.
