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 8:
Parr is said on one occasion to have called for a pipe after taking a meal at a coaching-inn called the "Bush" at Bristol, when the waiter told him that smoking was not allowed at the Bush. Parr persisted, but the authorities at the inn were firm in their refusal to allow anything so vulgar as smoking on their premises, whereupon Parr is said to have exclaimed: "Why, man, I've smoked in the dining-room of every nobleman in England. The Duchess of Devonshire said I could smoke in every room in her house but her dressing-room, and here, in this dirty public-house of Bristol you forbid smoking! Amazing! Bring me my bill." The learned doctor exaggerated no doubt as regards the facilities given him for smoking; for it was his overbearing way not to ask for leave to smoke, but to smoke wherever he went, whether invited to do so or not; but the story shows the prejudice against smoking which was found in many places as a result of the attitude of the fashionable world towards tobacco.
