When Ogareff had in his cruel irony held the Imperial letter before the eyes which he believed were destroyed, Michael had been able to read, and had read the letter which disclosed the odious plans of the traitor. This was the reason of the wonderful resolution he exhibited during the second part of his journey. This was the reason of his unalterable longing to reach Irkutsk, so as to perform his mission by word of mouth. He knew that the town would be betrayed! He knew that the life of the Grand Duke was threatened! The safety of the Czar’s brother and of Siberia was in his hands. This story was told in a few words to the Grand Duke, and Michael repeated also--and with what emotion!--the part Nadia had taken in these events. “Who is this girl?” asked the Grand Duke. “The daughter of the exile, Wassili Fedor,” replied Michael. “The daughter of Captain Fedor,” said the Grand Duke, “has ceased to be the daughter of an exile. There are no longer exiles in Irkutsk.” Nadia, less strong in joy than she had been in grief, fell on her knees before the Grand Duke, who raised her with one hand, while he extended the other to Michael. An hour after, Nadia was in her father’s arms. Michael Strogoff, Nadia, and Wassili Fedor were united. This was the height of happiness to them all. The Tartars had been repulsed in their double attack on the town. Wassili Fedor, with his little band, had driven back the first assailants who presented themselves at the Bolchaia Gate, expecting to find it open and which, by an instinctive feeling, often arising from sound judgment, he had determined to remain at and defend. At the same time as the Tartars were driven back the besieged had mastered the fire. The liquid naphtha having rapidly burnt to the surface of the water, the flames did not go beyond the houses on the shore, and left the other quarters of the town uninjured. Before daybreak the troops of Feofar-Khan had retreated into their camp, leaving a large number of dead on and below the ramparts. Among the dead was the gypsy Sangarre, who had vainly endeavored to join Ivan Ogareff. For two days the besiegers attempted no fresh assault. They were discouraged by the death of Ogareff. This man was the mainspring of the invasion, and he alone, by his plots long since contrived, had had sufficient influence over the khans and their hordes to bring them to the conquest of Asiatic Russia. However, the defenders of Irkutsk kept on their guard, and the investment still continued; but on the 7th of October, at daybreak, cannon boomed out from the heights around Irkutsk. It was the succoring army under the command of General Kisselef, and it was thus that he made known his welcome arrival to the Grand Duke. The Tartars did not wait to be attacked. Not daring to run the risk of a battle under the walls of Irkutsk, they immediately broke up the Angara camp. Irkutsk was at last relieved.
