The Lord de Joinville, the friend of king Louis, and one of the bravest of the French captains, gives a lively and most interesting account of the campaign, and of the exploits of the Templars. During the march towards Cairo, they led the van of the christian army, and on one occasion, when the king of France had given strict orders that no attack should be made upon the infidels, and that an engagement should be avoided, a body of Turkish cavalry advanced against them. “One of these Turks,” says Joinville, “gave a Knight Templar in the first rank so heavy a blow with his battle-axe, that it felled him under the feet of the Lord Reginald de Vichier’s horse, who was Marshal of the Temple; the Marshal, seeing his man fall, cried out to his brethren, ‘At them in the name of God, for I cannot longer stand this.’ He instantly stuck spurs into his horse, followed by all his brethren, and as their horses were fresh, not a Saracen escaped.” After marching for some days, the Templars arrived on the banks of the Tanitic branch of the Nile, (the ancient Pelusiac mouth of the river,) and found the sultan encamped with his entire force on the opposite side, to prevent and oppose their passage. King Louis attempted to construct a bridge to enable him to cross the stream, and long and earnestly did the Templars labour at the task, “but,” says Joinville, “as fast as we advanced our bridge the Saracens destroyed it; they dug, on their side of the river, wide and deep holes in the earth, and as the water recoiled from our bridge it filled these holes with water, and tore away the bank, so that what we had been employed on for three weeks or a month they ruined in one or two days.” To protect the soldiers employed upon the construction of the bridge large wooden towers were erected, and _chas chateils_ or covered galleries, and the infidels exerted all their energies to destroy them with the terrible Greek fire. “At night,” says Joinville, “they brought forward an engine called by them La Perriere, a dreadful engine to do mischief, and they flung from it such quantities of Greek fire that it was the most horrible sight ever witnessed.... This Greek fire was like a large tun, and its tail was of the length of a long spear; the noise which it made was like to thunder, and it seemed a great dragon of fire flying through the air, giving so great a light with its flame, that we saw in our camp as clearly as in broad day.”
