Nevertheless, as the day went on, and the tremendous roar of battle rolled down upon them--terrible, continuous, and never ceasing, for three hours--even Keith walked, in a state of feverish anxiety, backwards and forwards in front of his tent; while the troops stood in groups, talking in low tones, and trying to pierce with their eyes the dun-coloured cloud of smoke that hung over the combatants on the other side of Prague.

When at last the din of battle went rolling down towards that city, the feeling of joy was intense. In many, the relief from the tension and the long excitement was so great that they burst into tears. Some shook hands with each other, others threw their caps into the air, and then a few voices burst into the well-known verse of the church hymn:
Nun danket alle Gott,
Mit herzen, mund und haenden.
Of which our English translation runs:
Now thank we all our God,
With hands and hearts and voices.

And in a moment it was taken up by 30,000 deep voices, in a solemn chorus, the regimental bands at once joining in the jubilant thanksgiving. Pious men were these honest, Protestant, hard-fighting soldiers; and very frequently, on their long marches, they beguiled the way by the stirring hymns of the church. Keith and those around him stood bare-headed, as the hymn was sung, and not a word was spoken for some time after the strains had subsided.

"That is good to listen to," Keith said, breaking the silence. "We have often heard the psalm singing of Cromwell's Ironsides spoken of, with something like contempt; but we can understand, now, how men who sing like that, with all their hearts, should be almost invincible."

"It is the grandest thing that I have ever heard, marshal," Fergus said. "Of course, I have heard them when they were marching, but it did not sound like this."

"No, Fergus; it was the appropriateness of the occasion, and perhaps the depth of the feelings of the men, and our own sense of immense relief, that made it so striking.

"Listen! There is a fresh outburst of firing. The Austrians have fallen back, but they are fighting stoutly."

The chief effect of this great battle was of a moral, rather than material kind. Prague was not a strong place, but with a garrison of 50,000 men it was too well defended to assault; and until it was taken Frederick could not march on, as he had intended, and leave so great a force in the rear.

The moral effect was, however, enormous. The allies had deemed that they had a ridiculously easy task before them, and that Frederick would have to retreat before their advancing armies, and must at last see that there was nothing but surrender before him. That he should have emerged from behind the shelter of the Saxon hills, and have shattered the most formidable army of those that threatened him, on ground of their own choosing, intrenched and fortified, caused a feeling of consternation and dismay. The French army, the Russians, and the united force of the French with the German Confederacy were all arrested on their march, and a month elapsed before they were again set in motion.

Marshal Daun, who had arrived at Erdwise, fell back at once when the news reached him and, taking post at the entrance of the defile, he made the greatest efforts to increase his army. Reinforcements were sent to him from Vienna and all the adjacent country. The Duke of Bevern was posted with 20,000 men to watch him; and Frederick sat down, with all his force, to capture Prague.
