FORE:As soon as five or six thousand of his troops were landed, Buonaparte commenced his march on Alexandria. The Turks manned the walls, and resisted furiously, incensed at this invasion by a Power with which they were nominally at peace. But the walls were ruinous; the French forced their way over several breaches, and commenced an indiscriminate massacre. The place was abandoned to pillage for four hours. As the Mamelukes were hated by the Arabs and the Copts, and were the military mercenaries of the country, chiefly recruited from Georgia and Circassia, Buonaparte determined to destroy them. He considered that he should thus rid himself of the only formidable power in Egypt, and at the same time conciliate the Bedouins and Fellahs. On the 7th of July he set out on his march for Cairo with his whole force. He marched up the bank of the Nile, but at such a distance as to prevent the soldiers from getting any water to quench their burning thirst. It was all that Buonaparte could do to keep his troops in subordination. For fourteen days this melancholy march was continued, when they came at once in sight of the Pyramids, not far distant from Cairo, and of the army of the Mamelukes, drawn up across their way, headed by Murad Bey. This force consisted of five thousand cavalryMamelukes, mounted on the finest Arabian horses in the world, trained to obey the slightest touch of the rein, to advance, wheel, or fly with wonderful rapidity. The riders were all fine men, armed with sabres, pistols, and blunderbusses of the best English workmanship. They were deemed invincible and were ruthlessly cruel. They presented in appearance the finest body of cavalry in the world, the plumes of their turbans waving in the air, and their arms glittering in the sun. There were, moreover, twenty thousand infantry lying in a slightly-entrenched camp on their right;[467] but these were a mere rabblefellaheen, or, in other words, peasantry, brought from their fields, and armed with matchlocks. They had forty pieces of cannon to defend the camp, but these had no carriages, being mounted on clumsy wooden frames. Buonaparte drew up his army so as to keep out of gunshot of the camp, and to deal only with the cavalry first. He formed his troops into squares to resist the onslaught of the cavalry; and as he saw the Mamelukes come on, he called to his men, "From yonder Pyramids twenty centuries behold your actions!" The Mamelukes came thundering on like a whirlwind, and sending before them the most horrible yells. Murad Bey said he would cut up the French like gourds. One of the French squares was thrown into confusion, but it recovered itself, and the battle was instantly a scene of the most desperate fury. The Mamelukes fought like demons; but, finding that they could not break the French ranks, whilst they and their horses were mown down by musketry and artillery, in despair they flung their pistols at their foes, backed their horses up to them to break them by kicking, and finding all unavailing, fled. Such as were left wounded on the ground crept forward to cut at the legs of the French soldiers. Both cavalry and infantry then, by swimming their horses, or in boats, attempted to cross the Nile, but the greater part were drowned in the attempt. Murad Bey, with the residue of his Mamelukes, escaped into Upper Egypt.The troops of Austria were already in Bavaria on the 21st of August. They amounted to eighty thousand men, under the nominal command of the Archduke Ferdinanda prince of high courage and great hopesbut really under that of General Mack, whose utter incapacity had not been sufficiently manifested to Austria by his miserable failures in the Neapolitan campaign, and who was still regarded in Germany as a great military genius. His army had been posted behind the Inn, in the country between the Tyrol and the Danube, into which the Inn falls at Passau. This was a strong frontier, and had the Austrians waited there till the arrival of the Russians, they might have made a powerful stand. But Mack had already advanced them to the Lech, where again he had a strong position covering Munich. Meanwhile, the Archduke Charles, Austria's best general, was posted in the north of Italy, with another eighty thousand men, and the Archduke John in the Tyrol with an inferior force. Such were the positions of the Austrian armies when Mack was invading Bavaria, and Buonaparte was preparing to crush him.
