On Wednesday morning, December 15, the advance-guard of the Prussians saw before them the allied army, thirty-five thousand strong, occupying a very formidable position. Marshal Grüne and General Rutowski had advanced a few miles north from Dresden to meet the Prussians. Their troops were drawn up in battle array, extending from the River Elbe on the east, to the village of Kesselsdorf on the west. A small stream, with a craggy or broken gully or dell, extended along their whole front. The southern ridge, facing the advancing Prussians, bristled with artillery. Some of the pieces were of heavy calibre. Leopold had only light field-pieces.
In the cold of the winter morning the Old Dessauer carefully reconnoitred the position of his foes. Their batteries seemed innumerable, protected by earth-works, and frowning along a cliff which could only be reached by plunging into a gully and wading through a half-frozen bog. There was, however, no alternative but to advance or retreat. He decided to advance.
Forming his army in two parallel lines, nearly five miles long, facing the foe, he prepared to open the battle along the whole extent of the field. While thus engrossing the attention of the enemy, his main attempt was to be directed against the village of Kesselsdorf, which his practiced eye saw to be the key of the position. It was two o’clock in the afternoon ere all his arrangements were completed. The Old Dessauer was a devout man—in his peculiar style a religious man, a man of prayer. He never went into battle without imploring God’s aid. On this occasion, all things being arranged, he reverently uncovered his head, and in presence of the troops offered, it is said, the following prayer:
“O my God, help me yet this once. Let me not be disgraced in my old days. But if Thou wilt not help me, don’t help those scoundrels, but leave us to try it out ourselves.”
Having uttered this prayer, he waved his hat to his troops, and shouted, “On, in God’s name!”
“The Prussians,” writes Carlyle, “tramp on with the usual grim-browed resolution, foot in front, horse in rear. But they have a terrible problem at that Kesselsdorf, with its retrenched batteries and numerous grenadiers fighting under cover. The very ground is sore against them; up-hill, and the trampled snow wearing into a slide, so that you sprawl and stagger sadly. Thirty-one big guns, and near nine thousand small, pouring out mere death on you from that knoll-head. The Prussians stagger; can not stand; bend to rightward to get out of shot range; can not manage it this bout. Rally, re-enforced; try it again. Again with a will; but again there is not a way. The Prussians are again repulsed; fall back down this slippery course in more disorder than the first time. Had the Saxons stood still, steadily handling arms, how, on such terms, could the Prussians have ever managed it?”[90]
At the second repulse, the Saxon grenadiers, greatly elated, gave a shout of “victory,” and rushed from their works to pursue the retreating Prussians. This was their ruin.
“Old Leopold, quick as thought, noticing the thing, hurls cavalry on these victorious, down-plunging grenadiers; slashes them asunder into mere recoiling whirlpools of ruin, so that few of them got back unwounded; and the Prussians, storming in along with them, aided by ever new Prussians, the place was at length carried.”[91]
And now the Prussians from the centre press the foe with new vigor. Leopold, at the head of his victorious division, charged the allied troops in flank, pouring in upon them his resistless horsemen. Whole regiments were made prisoners. Ere nightfall of the short December day, the whole allied army, broken and disordered, was on the retreat back to Dresden. The night alone protected them from utter ruin. They had lost six thousand prisoners, and three thousand in killed and wounded.[92]
Prince Charles had arrived in Dresden the night before. He heard the roar of the cannonade all the day, but, for some unexplained reason, did not advance to the support of his friends. The very unsatisfactory excuse offered was, that his troops were exhausted by their long march; and that, having been recently twice beaten by the Prussians, his army would be utterly demoralized if led to another defeat.
