To what extent was Muslim success during the Crusades the result of their weapons and tactics?

Candidates will consider the merits or otherwise of the suggestion that Muslim success during the Crusades was the result of their weapons and tactics. Causes may predate the timeframe, but must be clearly linked to the issue raised in the question. Candidates may refer to the tactical skills of Muslim leaders such as Saladin, improvements in siege weapons which aided the Muslims, as did their mobility, geographic knowledge and strategy of avoiding pitched battles. Other relevant factors may be considered, such as the numerical weakness of the Western forces, the poor leadership shown in many cases by Western forces and the growing strength, unity and confidence of the Muslims after the First Crusade. Declining interest and support for the Crusades by Europe is also an important factor to consider. Candidates’ opinions or conclusions will be presented clearly and supported by appropriate evidence.
