This had been considered by the Grand Duke and his officers as fortunate. Should the channel of the Angara continue to be thus obstructed, the passage must be impracticable. The Tartars could use neither rafts nor boats. As to their crossing the river on the ice, that was not possible. The newly-frozen plain could not bear the weight of an assaulting column.
This circumstance, as it appeared favorable to the defenders of Irkutsk, Ogareff might have regretted. He did not do so, however. The traitor knew well that the Tartars would not try to pass the Angara, and that, on its side at least, their attempt was only a feint.
About ten in the evening, the state of the river sensibly improved, to the great surprise of the besieged and still more to their disadvantage. The passage till then impracticable, became all at once possible. The bed of the Angara was clear. The blocks of ice, which had for some days drifted past in large numbers, disappeared down the current, and five or six only now occupied the space between the banks. The Russian officers reported this change in the river to the Grand Duke. They suggested that it was probably caused by the circumstance that in some narrower part of the Angara, the blocks had accumulated so as to form a barrier.
We know this was the case. The passage of the Angara was thus open to the besiegers. There was great reason for the Russians to be on their guard.
Up to midnight nothing had occurred. On the Eastern side, beyond the Bolchaïa Gate, all was quiet. Not a glimmer was seen in the dense forest, which appeared confounded on the horizon with the masses of clouds hanging low down in the sky. Lights flitting to and fro in the Angara camp, showed that a considerable movement was taking place.

The bell of the Irkutsk cathedral was about to strike two o'clock in the morning, and not a movement amongst the besiegers had yet shown that they were about to commence the assault. The Grand Duke and his officers began to suspect that they had been mistaken. Had it really been
