Then arrived the Prince Alexius once more, with definite promises of money and men for the Crusades if the allies would come at once and win back for him the Constantinople throne. Dandolo, who saw immense Venetian advantage here, agreed, and carrying with it most of the French, the fleet sailed for the Golden Horn. Dandolo, I might remark, was now ninety-four, and it should not be forgotten that it was when he was an emissary of the Republic at Constantinople years before that he had been deprived forcibly of his sight. He was a soldier, a statesman, and (as all good Doges were) a merchant, but he was humanly mindful of past injustices too. Hence perhaps much of his eagerness to turn aside for Byzantium. The plan was for the French to attack on the land; the Venetians on the sea. Blind though he had become, Dandolo's memory of the harbour and fortifications enabled him to arrange the naval attack with the greatest skill, and he carried all before him, himself standing on the prow of a vessel waving the banner of S. Mark. The French on land had a less rapid victory, but they won, none the less, and the ex-king Isaac was liberated and crowned once more, with his son. Both, however, instantly took to tyranny and luxurious excess, and when the time came for the promises of reward to be fulfilled nothing was done. This led to the mortification and anger of the allies, who declared that unless they were paid they would take Constantinople for themselves. War was inevitable. Meanwhile the Greeks, hating alike Venetians, French, and the Pope, proclaimed a new king, who at once killed Alexius; and the allies prepared for battle by signing a treaty, drawn up by the wily nonagenarian, in which in the event of victory Venice took literally the lion's share of the spoils. The fighting then began. At first the Greeks were too strong, and a feeling grew among the allies that withdrawal was best; but Dandolo refused; they fought on, and Constantinople was theirs. Unhappily the victors then lost all control, and every kind of horror followed, including the wanton destruction of works of art beautiful beyond dreams. Such visible trophies of the conquest as were saved and brought back to Venice are now to be seen in S. Mark's. The four bronze horses were Dandolo's spoils, the Pala d'oro, probably the four carved columns of the high altar, and countless stone pillars and ornaments that have been worked into the structure. The terms of the treaty were carried out faithfully, and the French paid the Venetians their original debt. Baldwin, Count of Flanders, the head of the Crusade, was named Emperor and crowned; Venice acquired large tracts of land, including the Ionian Islands; and Dandolo became "Doge of Venice, Dalmatia, and Croatia, and Lord of one-fourth and one-eighth of the Roman Empire."
