Richard the Lion-Heart, like his predecessors, preferred to employ mercenaries for his wars, while even the knights who accompanied him to the Crusade were in receipt of pay. Were it not that his achievements in the Holy Land had left little mark on English military history they would be well worthy of a detailed narrative, for Richard was beyond dispute a really great soldier, a good engineer, and a remarkably able commander. The story of his march from Joppa to Jerusalem and of his victory at Arsouf is known to few, but it remains to all time an example of consummate military skill. A mixed force compounded of many nations is never very easy to control, and it was doubly difficult when the best of it was composed of knights who hated the very name of subordination. Yet it was with such material, joined to a huge body of half-disciplined infantry, that Richard executed a flank march in the presence of the most formidable of living generals, and repulsed him brilliantly when he ventured, at an extremely trying moment, to attack. The plan of the campaign, the arrangements and orders for the march, the drill and discipline imposed on the knights, and the handling of the troops in the action are all alike admirable. Yet, as has been already stated, the lessons of the Crusades wrought little influence in England, mainly because she had already learned from her own experience the value of a heavily armed infantry, and of the tactical combination of missile and striking weapons. In the rest of Europe they were for a time remembered but very soon forgotten;[10] and England was then once more left alone with her secret. Two small relics of the Crusades must however find mention in this place. The first is the employment of the cross as a mark for distinguishing the warriors of different nations, which became in due time the recognised substitute for uniform among European soldiers. Each nation took a different colour for its cross, that of the English being at first white, which, curiously enough, is now the regular facing for English regiments of infantry. The second relic is the military band which, there seems to be little doubt, was copied from the Saracens. In their armies trumpets and drums, the latter decidedly an Oriental instrument, were used to indicate a rallying-point; for though at ordinary times the standards sufficed to show men the places of their leaders, yet in the dust of battle these were often hidden from sight; and it was therefore the rule to gather the minstrels (such was the English term) around the standards, and bid them blow and beat strenuously and unceasingly during the action. The silence of the band was taken as a proof that a battalion had been broken and that the colours were in danger; and the fashion lasted so long that even in the seventeenth century the bandsmen in all pictures of battles are depicted, drawn up at a safe distance and energetically playing.
