Hardly was this accomplished when news arrived that the Turks were near at hand. Then the Grand Master ordered a muster of all the men capable of bearing arms, and began with the Knights, the flower of many races; and a splendid sight they were, in their scarlet tunics with a large white cross on the breast. To each he appointed his place, with his special duties, and next proceeded to the citizens and the strangers, giving them separate colours and mottoes, and forming them into companies. But at the most the defenders did not number more than 6,000, and who could tell how many the Turks might be? On June 18, 1522, the Turkish fleet was sighted, and for the next fortnight it moved from place to place in the neighbourhood of Rhodes, till it finally cast anchor about six miles from the town and remained there till the end of the siege. Four hundred ships, large and small, were said to be assembled, and for a fortnight some of the galleys went to and from the mainland, returning with fresh supplies and more soldiers. Meanwhile the Grand Master left his palace and took up his abode near the part of the walls where he expected the fight to be fiercest. He had need of vigilance; for more to be dreaded than the enemy without were the traitors within, though as yet none suspected de Merall of treason. But many of the women slaves serving in the houses of the rich were Turks, who sought to help their countrymen. This was to be done by setting fire to their masters' houses at the moment of the first assault, in order to tempt the soldiers to leave their posts at the defences, to put out the flames. Luckily the plot was betrayed and the leader executed before any harm was done. The Turkish male slaves, on the contrary, were faithful throughout, and as they numbered 1,500 were of great importance, working hard in the trenches. The walls were divided into different portions, called sometimes after the kingdoms and sometimes after provinces of countries. There was the 'gate of Italy,' the 'gate of Almaine' or Germany, the 'gate of Auvergne,' the 'gate of Provence,' the 'Walls of England and Spain'; and it was at these two walls that the first assault was directed. The Turks shot huge stones from their guns, and their engines cast them upwards into the air, so that they fell down with tremendous force into the street, but strangely enough they did little damage to anyone. Soon there arrived in Rhodes, from Candia, Captain Gabriel Martinengo and two other captains, all skilled in war, while the following day the young Sultan himself joined his fleet.
