Meanwhile the king and his army had reached their new quarters, where the utmost caution and noiselessness was observed. The king, wrapped in his military cloak, had fallen asleep beside his watch-fire; Ziethen, his valiant cavalry leader, and a few others of his principal officers, being with him. Throughout the camp the greatest stillness prevailed, all noise having been forbidden. The soldiers slept with their arms close at hand, and ready to be seized at a moment's notice. Frederick fully appreciated the peril of his situation, and was not to be taken by surprise by his active foes. And thus the night moved on until midnight passed, and the new day began its course in the small hours. About two o'clock a sudden change came in the situation. A horseman galloped at full speed through the camp, and drew up hastily at the king's tent, calling Frederick from his light slumbers. He was the officer in command of the patrol of hussars, and brought startling news. The enemy was at hand, he said; his advance columns were within a few hundred yards of the camp. It was Laudon's army, seeking to steal into possession of those heights which Frederick had so opportunely occupied. The stirring tidings passed rapidly through the camp. The soldiers were awakened, the officers seized their arms and sprang to horse, the troops grasped their weapons and hastened into line, the cannoneers flew to their guns, soon the roar of artillery warned the coming Austrians that they had a foe in their front. Laudon pushed on, thinking this to be some advance column which he could easily sweep from his front. Not until day dawned did he discover the true situation, and perceive, with astounded eyes, that the whole Prussian army stood in line of battle on those very heights which he had hoped so easily to occupy. The advantage on which the Austrian had so fully counted lay with the Prussian king. Yet, undaunted, Laudon pushed on and made a vigorous attack, feeling sure that the thunder of the artillery would be borne to Daun's ears, and bring that commander in all haste, with his army, to take part in the fray. But the good fortune which had so far favored Frederick did not now desert him. The wind blew freshly in the opposite direction, and carried the sound of the cannon away from Daun's hearing. Not the roar of a piece of artillery came to him, and his army lay moveless during the battle, he deeming that Laudon must now be in full possession of the heights, and felicitating himself on the neat trap into which the King of Prussia had fallen. While he thus rested on his arms, glorying in his soul on the annihilation to which the pestilent Prussians were doomed, his ally was making a desperate struggle for life, on those very heights which he counted on taking without a shot. Truly, the Austrians had reckoned without their foe in laying their cunning plot.
