Brother Bertrand de Blanquefort, in his letters to the king of France, gives an account of the military operations undertaken by the order of the Temple in Egypt, and of the capture of the populous and important city of Belbeis, the ancient Pelusium.[17] During the absence of the Master with the greater part of the fraternity on that expedition, the sultan Noureddin invaded Palestine; he defeated with terrible slaughter the serving brethren and Turcopoles, or light horse of the order, who remained to defend the country, and sixty of the knights who commanded them were left dead on the plain. Amalric, king of Jerusalem, the successor of Baldwin the Third, in a letter “to his dear friend and father,” Louis the Seventh, king of France, beseeches the good offices of that monarch in behalf of all the devout Christians of the Holy Land; “but above all,” says he, “we earnestly entreat your Majesty constantly to extend to the utmost your favour and regard to the Brothers of the Temple, who continually render up their lives for God and the faith, and through whom we do the little that we are able to effect, for in them indeed, after God, is placed the entire reliance of all those in the eastern regions who tread in the right path.”[18] The Master, Brother Bertrand de Blanquefort, was succeeded, (A. D. 1167,) by Philip of Naplous, the first Master of the Temple who had been born in Palestine. He had been Lord of the fortresses of Krak and Montreal in Arabia Petræa, and took the vows and the habit of the order of the Temple after the death of his wife.[19]
