On the 2nd of May, twelve days after moving from Saxony, Frederick arrived within sight of Prague. So closely had he followed the retreating Austrians that he occupied, that evening, a monastery at which Prince Karl and Marshal Browne had slept the night before.

Thirty thousand men, who were under the command of Marshal Keith, were left to watch Prague and its garrison; while Frederick, on Tuesday, searched for a spot where he could cross the river and effect a junction with Schwerin. He knew his position, and had arranged that three cannon shots were to be the signal that the river had been crossed.

A pontoon bridge was rapidly thrown over, the signal was given, and the Prussians poured across it; and before the whole were over Schwerin's light cavalry came up, and an arrangement was made that the two forces should meet, at six o'clock next morning, at a spot within two miles of the Austrian camp on the Lisca hills.

All this time the Austrians stood inactive, and permitted the Prussian columns to join hands without the slightest attempt to interfere with them. Had Browne been in command, very different steps would have been taken; but Prince Karl was indolent, self confident, and opinionated, and had set his army to work to strengthen its position in every possible manner. This was naturally extremely strong, its right flank being covered by swampy ground formed by a chain of ponds; from which the water was let off in the winter, and the ground sown with oats. These were now a brilliant green, and to the eyes of Frederick and his generals, surveying them from the distance, had the aspect of ordinary meadows. The whole ground was commanded by redoubts and batteries on the hill, which rose precipitately seven or eight hundred feet behind the position. In the batteries were sixty heavy cannon; while there were, in addition, one hundred and fifty field guns.

Well might Prince Karl think his position altogether una.s.sailable, and believe that, if the Prussians were mad enough to attack, they would be destroyed. Frederick and Schwerin spent much time in surveying the position, and agreed that on two sides the Austrian position was absolutely impregnable; but that on the right flank, attack was possible. Schwerin would fain have waited until the next morning, since his troops were fatigued by their long marches, and had been on foot since midnight. The Austrians, however, were expecting a reinforcement of thirty thousand men, under Daun, to join them hourly; and the king therefore decided on an attack, the terrible obstacles presented by the swamps being altogether unnoticed.

With incredible speed the Prussians moved away to their left, and by eleven o'clock were in readiness to attack the right flank of the Austrian position. Browne, however, was in command here and, as soon as the intention of the Prussians was perceived, he swung back the right wing of the army at right angles to its original position, so that he presented a front to the Prussian attack; ma.s.sing thickly at Sterbold, a village at the edge of the swamps.

Rapidly the whole of the artillery and cavalry were formed up on this face and, quick as had been the advance of the Prussians, the Austrians were perfectly ready to meet them.

Led by General Winterfeld, the Prussians rushed forward; but as they advanced, a terrific artillery fire was opened upon them.

Winterfeld was wounded severely, and the troops fell back.

The main body now advanced, under Schwerin, and the whole again pressed forward. In spite of the incessant rain of grape and case shot, the Prussians advanced until they reached the pleasant green meadows they had seen in the distance. Then the real nature of the ground was at once disclosed.

The troops sunk to the knee, and in many cases to the waist, in the treacherous mud. Soldiers less valiant and less disciplined would have shrunk, appalled at the obstacle; but the Prussians struggled on, dragging themselves forward with the greatest difficulty through mud, through slush, through a rain of grape from upwards of two hundred cannon, and through a storm of musketry fire from the infantry. Regiment after regiment, as it reached the edge of the dismal swamp, plunged in unhesitatingly, crawling and struggling onward.

Never in the annals of warfare was there a more terrible fight. For three hours it continued, without a moment's interval. Thousands of the a.s.sailants had fallen, and their bodies had been trodden deep into the swamp, as their comrades pressed after them. Sometimes a regiment struggled back out of the mire, thinking it beyond mortal power to win victory under such terms; but the next moment they reformed and flung themselves into the fight again. Schwerin, seeing the regiment named after him recoil, placed himself at their head; and shouting, "Follow me, my sons!" led them till he fell dead, struck by five grape shot.

The Austrians fought as stoutly, Marshal Browne leading them till a cannonball took off his foot, and he was carried into Prague, to die there six weeks later.

While this terrible struggle was going on, the Prussian cavalry had made a very wide circuit round the ponds and lakelets, and charged the Austrian horse on Browne's extreme right. The first lines were broken by it, but so many and strong were they that the Prussians were brought to a standstill. Then they drew back and charged a second, and a third time.

The Austrians gave way. Prince Karl himself, brave if incapable, did his best to rally them, but in vain; and at last they fled in headlong rout, pursued for many miles by Ziethen's hors.e.m.e.n.

Still the infantry struggle was maintained. At last the Prussian right wing, hitherto not engaged, though suffering from the artillery fire on the heights, had their turn. General Mannstein discovered that, at the angle where Browne threw back the right wing of the army to face the Prussians, there was a gap. The troops there had gradually pressed more to their right, to take part in the tremendous conflict; and the elbow was, therefore, defended only by a half-moon battery.

Through the fish tanks he led the way, followed by Princes Henry and Ferdinand. The whole division struggled through the mud, drove back the Austrians hastily brought up to oppose them, captured the battery, and poured into the gap; thereby cutting the Austrian army in two, and taking both halves in flank.

This was the deciding point of the battle. The Austrian right, already holding its own with difficulty, was crumpled up and forced to fall back hastily. The other half of the army, isolated by the irruption, threw itself back and endeavoured to make a fresh stand at spots defended by batteries and stockades.

But all was in vain. The Prussians pressed forward exultingly, the fresh troops leading the way. In spite of the confusion occasioned by the loss of their commanders, and of the surprise caused by the sudden breakup of their line by the inrush of Mannstein and the princes, the Austrians fought stoutly. Four times they made a stand, but the Prussians were not to be denied. The Austrian guns that had been captured were turned against them and, at last giving way they fled for Prague, where some 40,000 of them rushed for shelter, while 15,000 fled up the valley of the Moldau.

Had it not been that an accident upset Frederick's calculations, the greater portion of the Austrians would have been obliged to lay down their arms. Prince Maurice of Dessau had been ordered to move with the right wing of Keith's army, 15,000 strong, to take up a position in the Austrian rear. This position he should have reached hours before, but in his pa.s.sage down a narrow lane, some of the pontoons for bridging the river were injured. When the bridge was put together, it proved too short to reach the opposite bank.

The cavalry in vain endeavoured to swim the river. The stream was too strong, and Frederick's masterly combination broke down; and the bulk of the Austrians, instead of being forced to surrender, were simply shut up in Prague with its garrison.

The battle of Prague was one of the fiercest ever fought. The Austrian army had improved wonderfully, since the Silesian war.

Their artillery were specially good, their infantry had adopted many of the Prussian improvements and, had Browne been in sole command, and had he escaped unwounded, the issue of the day might have been changed. 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. There can therefore be little doubt that the latter must have suffered, in killed and wounded, a much heavier loss than the Austrians.

Impa.s.sive 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.

In Keith's army there had been considerable disappointment, when it became known that they were to remain impa.s.sive spectators of the struggle, and that while their comrades were fighting, they had simply to blockade the northern side of the city.

"You will have plenty of opportunities," the marshal said quietly to his aides-de-camp, on seeing their downcast look. "This war is but beginning. It will be our turn, next time. For it is a great task the king has set himself, in attempting to carry the strong position that the Austrians have taken up; and he will not do it without very heavy loss. Tomorrow you may have reason to congratulate yourselves that we have had no share in the business."

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 G.o.d, 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 a.s.sault; 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.

The siege train was hurried up from Dresden, and on the 9th of May his batteries on the south side of the city, and those of Keith on the north, opened fire on the city. For a month missiles were poured into the town. Magazines were blown up, and terrible destruction done, but the garrison held out firmly. At times they made sorties, but these were always driven in again, with much loss. But 50,000 men behind fortifications, however weak, were not to be attacked. Every approach to the city was closely guarded, but it became at last evident that, as long as the provisions held out, Prague was not to be taken.

The cannonade became less incessant, and after a month almost died away; for Daun had by this time gathered a large army, and it was evident that another great battle would have to be fought. If this was won by the Prussians, Prague would be forced to surrender. If not, the city was saved.

It was not until the 12th of June that Daun, a cautious and careful general, in accordance with urgent orders from Vienna prepared to advance. His force had now grown to 60,000; 40,000 of the garrison of Prague could be spared, to issue out to help him. Frederick had under 70,000, and of these a great portion must remain to guard their siege works. Thus, then, all the advantages lay with the relieving army.

Several officers in disguise were despatched, by Daun, to carry into Prague the news of his advance; and to warn Prince Karl to sally out, with the whole of his force, and fall upon the Prussians as soon as he attacked them in the rear. So vigilant, however, were the besiegers that none of these messengers succeeded in entering Prague.

On the 13th Frederick set out, with 10,000 men--to be followed by 4000 more under Prince Maurice, two days later, these being all that could be spared from the siege works--to join Bevern, who had fallen back as Daun advanced. The junction effected, Frederick joined Bevern and approached Daun, who was posted in a strong position near Kolin, thirty-five miles from Prague. On the 17th Prince Maurice arrived, and after several changes of position the armies faced each other on the 18th, within a short distance of Kolin.

Daun's new position was also a strong one, and was, in fact, only to be a.s.sailed on its right; and the Prussian army was moved in that direction, their order being to pay no attention to the Austrian batteries or musketry fire, but to march steadily to the spot indicated. This was done. Ziethen dashed with his hussars upon the Austrian cavalry, drawn up to bar the way; defeated them, and drove them far from the field; while Hulsen's division of infantry carried the village of Preezer, on the Austrian flank, in spite of the Austrian batteries. So far Frederick's combination had worked admirably.

Hulsen then attacked a wood behind it, strongly held by the Austrians. Here a struggle commenced which lasted the whole day, the wood being several times taken and lost. He was not supported, owing to a mistake that entirely upset Frederick's plan of battle.

While three miles away from the point where the attack was to be delivered, Mannstein, whose quickness of inspiration had largely contributed to the victory of Prague, now ruined Frederick's plan by his impetuosity. The corn fields, through which his division was marching towards the a.s.sault of the Austrian left, were full of Croats; who kept up so galling a fire that, losing all patience, he turned and attacked them.

The regiment to which he gave the order cleared the Croats off; but these returned, strongly reinforced. The regiments coming behind, supposing that fresh orders had arrived, also turned off; and in a short time the whole division, whose support was so sorely needed by Hulsen, were a.s.saulting the almost impregnable Austrian position in front.

Another mistake--this time arising from a misconception of a too brief and positive order, given by Frederick himself--led Prince Maurice, who commanded the Prussian centre, to hurl himself in like manner against the Austrians.

For four hours the battle raged. In spite of their disadvantages, the Prussians fought so desperately that Daun believed the day to be lost, and sent orders to the troops to retreat to Suchdol; but the commander of the Saxon cavalry considered the order premature and, gathering a large body of Austrian infantry, charged with them and his own cavalry so furiously upon Hulsen that the latter was forced to retreat.
