Beginning from these invincible feelings, and the principles of justice which are involved in them; let nothing be neglected, which policy and prudence dictate, for rendering subservient to the same end those qualities in human nature which are indifferent or even morally bad; and for making the selfish propensities contribute to the support of wise arrangements, civil and military.—­Perhaps there never appeared in the field more steady soldiers—­troops which it would have been more difficult to conquer with such knowledge of the art of war as then existed—­than those commanded by Fairfax and Cromwell:  let us see from what root these armies grew.  ‘Cromwell,’ says Sir Philip Warwick, ’made use of the zeal and credulity of these persons’ (that is—­such of the people as had, in the author’s language, the fanatic humour); ’teaching them (as they too readily taught themselves) that they engaged for God, when he led them against his vicegerent the King.  And, where this opinion met with a natural courage, it made them bolder—­and too often crueller; and, where natural courage wanted, zeal supplied its place.  And at first they chose rather to die than flee; and custom removed fear of danger:  and afterwards—­finding the sweet of good pay, and of opulent plunder, and of preferment suitable to activity and merit—­the lucrative part made gain seem to them a natural member of godliness.  And I cannot here omit’ (continues the author) ’a character of this army which General Fairfax gave unto myself; when, complimenting him with the regularity and temperance of his army, he told me, The best common soldiers he had—­came out of our army and from the garrisons he had taken in.  So (says he) I found you had made them good soldiers; and I have made them good men.  But, upon this whole matter, it may appear’ (concludes the author) ’that the spirit of discipline of war may beget that spirit of discipline which even Solomon describes as the spirit of wisdom and obedience.’  Apply this process to the growth and maturity of an armed force in Spain.  In making a comparison of the two cases; to the sense of the insults and injuries which, as Spaniards and as human Beings, they have received and have to dread,—­and to the sanctity which an honourable resistance has already conferred upon their misfortunes,—­add the devotion of that people to their religion as Catholics;—­and it will not be doubted that the superiority of the radical feeling is, on their side, immeasurable.  There is (I cannot refrain from observing) in the Catholic religion, and in the character of its Priesthood especially, a source of animation and fortitude in desperate struggles—­which may be relied upon as one of the best hopes of the cause.  The narrative of the first siege of Zaragoza, lately published in this country, and which I earnestly recommend to the reader’s perusal, informs us that,—­’In every part of the town where the danger was most imminent, and the French the most numerous,—­was Padre
