Solyman at one time tried persuasion on the Shah, reminding him of the treaty, by which he had agreed they should both have the same friends and enemies, and at another, endeavoured to frighten him with menacing language and threatened him with war, if Bajazet were not surrendered. He had placed strong garrisons in all his towns on the Persian frontier, and filled Mesopotamia and the bank of the Euphrates with soldiers, who were taken for the most part from the Imperial guard, and the troops he had employed against Bajazet. These forces were commanded by Mehemet Pasha, the third of the Vizierial Pashas, and the Beyler bey of Greece, for Selim had soon returned home. He also sent frequent messages to the tribes they call Georgians, who dwell between the Caspian and the Black Sea, and border on Media, urging them to take up arms against the King of Persia. They sagaciously replied that ‘they had not sufficient confidence in their own strength to venture to attack Shah Tahmasp by themselves; let Solyman only come with his army and they would know, when they saw him on the spot, what they ought to do. In that case they would be wanting neither in counsel nor in courage.’ In another direction are still to be found five Turkoman chiefs descended from Tamerlane; and these also were invited to join their arms against the common foe. Solyman wished it to be believed that he himself was going to Aleppo, a city of Syria on the banks of the Euphrates,[258] and that he intended from that base to make war on the King of Persia. Nor was the latter free from apprehension, as he had too often experienced the might of Solyman’s arm. But the angry Sultan was completely checked by the opposition of the soldiers and the reluctance they felt to engaging in such a war. They shrank from an unnatural contest, and began to desert. A great number of them, especially of the cavalry, returned to Constantinople, without orders from their commanders, and when bidden to return to the camp without delay, though they obeyed, they did so in such a way as to leave it evident how little they could be relied on, if any accident or change should occur.
