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 6:
The clay pipes called "aldermen," with longer stems than their predecessors, tipped with glaze, came into use towards the end of the seventeenth century. They must not be confused with the much longer "churchwarden" or "yard of clay" which was not in vogue till the early years of the nineteenth century.
