"The same, serene hetman!" answered the dragoons.

Hmelnitski turned to the colonels surrounding him. "Forward!" commanded he, with thundering voice.

Less than an hour later the tabor was moving on, though the sun was already setting and the night did not promise to be clear. Certain terrible reddish clouds rolled along on the western side of the heavens, like dragons or leviathans, and approached one another as if wishing to begin battle.

The tabor turned to the left, toward the bank of the Dnieper. The host marched quietly, without songs, without noise of drums or trumpets, and as quickly as the grass permitted, which was so luxuriant in that neighborhood that the regiments buried in it were lost from view at times, and the many-colored flags seemed to sail along the steppe. The cavalry beat a road for the wagons and the infantry, which, advancing with difficulty, soon fell considerably in the rear.

Night covered the steppes. An enormous red moon rose slowly in the heavens, but, hidden repeatedly by the clouds, flamed up and was quenched like a lamp smothered by the blowing of the wind.

It was well after midnight when, to the eyes of the Cossacks and the Tartars, black gigantic masses seemed outlined clearly on the dark background of the sky. These were the walls of Kudák.

Scouts, hidden by darkness, approached the fortress as carefully and quietly as wolves or night-birds. And now perhaps a surprise for the sleeping fortress!

But suddenly a flash on the ramparts rent the darkness. A terrible report shook the rocks of the Dnieper, and a fiery ball, leaving a circle of sparks in the air, fell among the grass of the steppe. The gloomy cyclops Grodzitski gave notice that he was watching.

"The one-eyed dog!" muttered Tugai Bey to Hmelnitski; "he sees in the night."

The Cossacks avoided the fortress and marched on. They could not think of taking it at a time when the armies of the crown were marching against them. But Grodzitski fired after them from his cannon till the walls of the fortress trembled; not so much to injure them--for they passed at a good distance--as to warn the troops sailing down the Dnieper, who at that time might be not far away.
