It was divided into two divisions of twenty-five ships each, one led by the _Ithuriel_ and the other by the _Isma_, and these rose into the air, formed in two straight lines each about a quarter of a mile long. The two flagships flew one on either flank, and slightly ahead and above the main body. This formation enabled any signals made from either of them to be instantly seen by every ship in the fleet. The distance to be traversed was five thousand eight hundred geographical miles, and the voyage was performed at a speed of four hundred miles an hour without incident. At daybreak on the 20th, the two divisions were floating in a wide circle six thousand feet above Alexandria at a sufficient distance to be practically invisible from the city, which nevertheless lay completely at the mercy of the four hundred guns which were trained upon it, and which, if the terms of the Council’s ultimatum were not accepted by the Sultan and Olga, would reduce it to a wilderness of ruins within an hour from the signal to fire being given. That the Russians were still the guests of the Sultan was made apparent as soon as the light became strong enough for their squadron to be seen resting on the earth in the gardens of the palace, with one look-out ship stationed about fifteen hundred feet above the roof of the palace. When all the ships were in their stations the _Ithuriel_ and the _Isma_ ran up close to each other, and Alexis boarded the flagship to receive his final instructions from Alan, who had undertaken the perilous duty of conveying the ultimatum to the Sultan and his possible ally. Orloff Lossenski was on board the _Ithuriel_, and Alan requested him to be present when Alexis received his orders. As he shook hands with the Vice-Admiral, Alan said-- “I have asked Orloff Lossenski to hear our last arrangements made so that he may recognise as well as we do that this is a matter of life and death for all of us. For my own part, I am determined that the wishes of the Council shall be obeyed, or the _Ithuriel_ and her crew shall be buried with our enemies in the ruins of Alexandria. “We have not been seen yet from the Russian look-out ship, but they will of course see the _Ithuriel_ going down. I shall descend flying a flag of truce, and I feel certain that the Sultan will recognise it himself and compel his allies to do so. But if not, if a single shot is fired, or if the Russian squadron attempts to rise in the air until my return, you are to give the signal to open fire upon the city, and the fleet is not to cease firing until it is destroyed. “You are to forget that you are destroying friends as well as foes, for I and all on board the _Ithuriel_ recognise that the honour of Aeria and the safety of the world demand the sacrifice, and we are resolved to make it.
