The evidence in their favour is, however, not weak. First and foremost, John Justiniani was a Genoese. His loyalty and the bravery and labours day and night of the Genoese soldiers were beyond cavil. Ducas himself states that the Genoese sent men from Galata who fought valiantly under Justiniani; that many of them acted as spies, sold provisions to the Turks, and secretly during the night brought to the Greeks the news they had gathered. The Podestà of Galata, writing shortly after the capture of the city, declares that every available man had been sent across the Horn to the defence of the walls. He protests that he had done his best, because he knew that if Constantinople were lost, the loss of Pera would follow.[355] The truth appears to be that the sympathy of the Podestà and the leading men was with their fellow Christians, but that the hostility of the Greeks and trade rivalry caused many of the Genoese too often to regard them as enemies. The Podestà is probably correctly expressing his own opinion and that of the better Genoese in stating that he foresaw that if Mahomet captured Constantinople, Galata would become an easy prey. But the certainty of making a good profit by dealing with the enemy was too great a temptation to be resisted by the ordinary merchant. Under cover of night he passed safely across the harbour and sold his goods to the citizens. He was equally ready during the day to deal with the Turks. The statement of Pusculus that the Genoese informed Mahomet by signal of the departure of the ships upon their night attack to burn the Turkish vessels which had been transported overland may be accepted as true, but the signal was probably the act of a private individual, for which the colony ought not to be held responsible. The boast reported by Ducas as having been made by the notables to Mahomet that they could have prevented the transport of the ships showed at least that they endeavoured to persuade him that they were neutral. It is by no means certain that had the Genoese desired to destroy the ships during the transit they could have made the attempt with a reasonable hope of success. They were far too few to meet the Turks outside the walls. However this may have been, they remained faithful to the conditions of the treaty which had existed before the time of Mahomet and which had been confirmed while he was at Adrianople on the express condition that they should not give aid to Constantinople. Even the complaint of Leonard that they could have saved the city if they had endeavoured to prevent Mahomet from securing a base of operations by building the fortifications at Hissar is a complaint against the policy of neutrality. It would no doubt have been not only more in accordance with the crusading spirit but possibly wiser and better in the interest of Europe and of civilisation if the Genoese, as Leonard suggests that they ought to have done, had violated
