Calling out to all islamic generals, I challenge you to remove the crusaders from the Holy Land! Yes this is a Jihad against the infidels
The challenge is to play a campaign as Egypt or the Turks on VH/VH and defeat both the Kingdom of Jerusalem and Antioch. They are heavily fortified with permanent garrisons at Jerusalem, Acre, Antioch and Krak de Chevaliers.
Also they have very strong units and the backing of the pope. Attacks against christendom will almost certainly result in Crusades against you. Can you take on the christian armies and win? I suspect you cannot, and lay down this challenge to all of you.
good luck
Dave
