No post could have been more in accordance with the desire of Gervaise, for the portion of the wall defended by the English langue was far removed from the point selected by the Turks for their first attack, the sea front being defended half by the langue of Italy, and half by that of Castile. Fort St. Nicholas was under the command of the Cavalier Caretto, and as soon as the Turkish battery was completed, Gervaise went down there with an order from the grand master that he was for the present to consider himself as forming part of the garrison. This was pleasant for both Caretto and himself, for the Italian knight had conceived a strong friendship for the young Englishman, and had rejoiced greatly at his return from captivity, but had been so much occupied with his duty of placing the castle in all respects in a state of defence, that he had had no opportunity for a private conversation with him since his return to Rhodes. Gervaise, on his part, was no less pleased. Caretto had shown so much tact after his release from the Moors, and had so willingly aided him in any capacity allotted to him, without in the slightest degree interposing his council unasked, that Gervaise had come to like him greatly, even before their arrival at Genoa. Circumstances there had brought them closely together, and their friendship had been cemented during their voyage to Rhodes. Caretto had gone back to Italy, where he had a commandery, a few days after Gervaise had sailed on his last voyage, and had only returned to Rhodes three months before Gervaise escaped from captivity. “This is turning the tables,” Caretto said, with a laugh, when Gervaise presented the grand master's order. “I was under your command last time, and now it seems that you are to be under mine. I suppose you applied to come here, in order to have a fresh opportunity of distinguishing yourself. I heard that you had been placed on D'Aubusson's own staff.” “Yes, and am on it still; and it is by his orders and not by my own solicitation that I am here. I will tell you what my duties are. The grand master knows the commanders of posts have their hands so full that they will have no time for sending complete reports to him, and he considers, moreover, that they might, in some cases, however pressed, hesitate to ask for aid until too late for reinforcements to be brought up. My duty will be to let the grand master know how matters are going, and to send to him at once if it seems to me that help is needed. I should, of course, always send for reinforcements, at the request of a commander; but it is only in the event of his being too busy in the heat of the fray to think of aught but resisting an attack, that I should exercise my own judgment in the matter.” Caretto nodded.
