The Grand Duke remained for a few minutes without speaking. He read the letter slowly, so as to take in its meaning fully. "Michael Strogoff, do you know the contents of this letter?" he asked.

"Yes, your Highness. I might have been obliged to destroy it, to prevent its falling into the hands of the Tartars, and should such have been the case, I wished to be able to bring the contents of it to your Highness."

"You know that this letter enjoins us all to die, rather than give up the town?"

"I know it."

"You know also that it informs me of the movements of the troops which have combined to stop the invasion?"

"Yes, your Highness, but the movements have failed."

"What do you mean?"

"I mean that Ichim, Omsk, Tomsk, to speak only of the more important towns of the two Siberias, have been successively occupied by the soldiers of Feofar-Khan."

"But there has been fighting? Have not our Cossacks met the Tartars?"

"Several times, your Highness."

"And they were repulsed?"

"They were not in sufficient force to oppose the enemy."
