The Prussians lost 12,500 men, killed and wounded; the Austrians, including prisoners, 13,300.

Frederick himself put the losses higher, estimating that of the Austrians at 24,000, of whom 5000 were prisoners, that of the Prussians at 18,000, "without counting Marshal Schwerin, who alone was worth about 10,000." It is evident that the king's estimate of the loss of the Austrians must have been excessive.

They had the advantage of standing on the defensive.

The Prussian guns did but comparatively little service, while their own strong batteries played with tremendous effect upon the Prussians, struggling waist deep in the mud.

Impassive as he was, and accustomed to show his feelings but little, Frederick was deeply affected at the loss of his trusted general, and of the splendid soldiers who had been so long and carefully trained; and even had Prague fallen, the victory would have been a disastrous one for him; for, threatened as he was by overwhelming forces, the loss of 5000 men, to him, was quite as serious as that of 20,000 men to the Confederates.
