"His best memorial is his history. Its pages reveal the thoroughness of his workmanship and his single-minded devotion to truth. The book was based on a mass of materials hitherto unknown or imperfectly utilised, and those materials were weighed and sifted with scientific skill. Each new edition was corrected with conscientious care as fresh evidence came to light. In his narrative minute accuracy and wide research were combined with sound judgment, keen insight, and a certain power of imagination. Earlier historians of the period, and some of Gardiner's own contemporaries, had written as partisans. Gardiner succeeded in stating fairly and sympathetically the position and the aims of both parties. He did not confine himself to relating facts, but traced the growth of the religious and constitutional ideas which underlay the conflict. No side of the national life was neglected. He won the praise of experts by his accounts of military and naval operations, elucidated continually the economic and social history of the time, and was the first to show the interaction of English and continental politics. The result of his labours was to make the period he treated better known and better understood than any other portion of English history. A narrative which fills eighteen volumes and took forty years to write is necessarily somewhat unequal as a literary composition. Many critics complained that Gardiner's style lacked the picturesqueness and vivacity of Macaulay or Froude; others that his method was too chronological. There was truth in both criticisms; but the chronological method was chosen because it enabled the historian to show the development of events far better than a more artificial arrangement would have done. He sought to interest his readers by his lucid exposition of facts and the justice of his reflections rather than by giving history the charms of fiction, and was content with the distinction of being the most trustworthy of nineteenth-century historians."
