These calamitous transactions in Palestine greatly alarmed all Europe, and several princes speedily resolved to oppose the career of the oppressors, and to leave no means untried of regaining the kingdom of Jerusalem. In furtherance of this design, the Emperor Frederic marched into Palestine with a powerful army, and defeated the Turks near Melitena; he afterwards met them near Comogena, where he also routed them, but was unhappily killed in the action. Some time after this, King Philip, of France, and Richard I., of England, engaged in a crusade for the relief of the Christians. Philip arrived first, and proceeded to Ptolemais, which King Guy, having obtained his liberty, was then besieging. King Richard, in his passage, was driven with his fleet upon the coast of Cyprus, but was not permitted to land; this so highly offended him, that he landed his whole army by force, and soon over-ran the island. He was at length opposed by the king of Cyprus, whom he took prisoner, and carried in chains to Ptolemais, where he was welcomed with great rejoicings by the besiegers, who stood in much need of assistance. It would he superfluous to relate here the particulars of the siege; let it suffice to say, that after a general assault had been given, a breach was made, so that the assailants were enabled to enter the city, which Saladin surrendered to them upon articles, on the 12th of July, 1191. King Richard here obtained the title of _Coeur de Lion_, for having taken down Duke Leopold's standard, that was first fixed in the breach, and placed his own in its stead. After the taking of Ptolemais, King Philip and many other princes returned home, leaving King Richard in Palestine to prosecute the war in concert with Guy, whom Richard, in a short time afterwards, persuaded to accept of the crown of Cyprus, in lieu of his pretences to Jerusalem. By these crafty means, Richard caused himself to be proclaimed King of Jerusalem; but while he was preparing to besiege that city, he received news that the French were about to invade England. He was therefore compelled to conclude a peace with Saladin, not very advantageous to Christendom, and to return to Europe. But meeting with bad weather, he was driven on the coast of Histria; and, while endeavouring to travel through the country in the habit of a templar, was taken prisoner by Duke Leopold, of Austria, who became his enemy at the siege of Ptolemais. The duke sold him for forty thousand pounds to the emperor, Henry VI., who soon afterwards had a hundred thousand pounds for his ransom.
