At Constantinople he had some devoted partisans, and through them he tried to tamper with the Sultan’s bodyguard by every means in his power, and on some occasions he even ventured to cross over to Constantinople himself,[202] concealing himself there among his accomplices and the men of his party.

The progress of the conspiracy was no secret to Solyman, who, besides his other channels of information, received accurate intelligence from Selim, who wrote despatches from time to time, warning his father to be on his guard against attack. ‘The Sultan was mistaken,’ said Selim, ‘if he thought that the impious designs which Bajazet was now rehearsing were not ultimately aimed at his own person. Bajazet cared neither for God nor man, provided he could reach the throne. His father was as great a barrier as his brother to the accomplishment of his ambitious hopes. Attacks on himself were aimed at Solyman’s life, a crime which Bajazet had planned long ago, and had lately been trying to carry into execution. He begged the Sultan to take care he did not fall a victim to these plots, and find himself a prisoner before news of his danger could be received or help sent to him. As to the personal wrongs he received from Bajazet, he could afford to disregard them, but he was troubled at the greatness of his father’s peril.’

By such insinuations fresh fuel was continually added to Solyman’s wrath against Bajazet. Accordingly he wrote letters reminding him of his duty, of the clemency with which he had treated him, and of his promises to himself, and bade him remember what he had said on a former occasion, viz., that he would not always find pardon, that he ought to turn over a new leaf, and not persist in provoking his brother and annoying his father.[203] He added that he had but a short span of life left himself, and when he was dead Providence would determine what their several lots should be. In the meantime they should keep quiet, if they had any regard for the peace of their father and their country. But such arguments were all thrown away upon Bajazet, who had made up his mind to hazard everything rather than take the other alternative, and tamely wait till the time came for him to be butchered like a sheep, which would most assuredly be his fate, if Selim ascended the throne.
