The reference to “accident of birth” is to the fact that before the battle of Jena (1806) practically every Prussian officer was an aristocrat, a rule which it will be remembered from a previous reference in this work obtained in the French army before the Revolution.

During a journey to Berlin, undertaken in his holidays, Varnhagen tells us that he was “reminded all along the road, that we were on the eve of some great event; in every direction we met soldiers in larger or smaller detachments, with artillery and baggage waggons. In Treuenbriezen I saw old Field Marshal von Müllendorf on his way to join the army; war was no longer doubtful, and it was thought that the presence of one of Frederick the Great’s heroes would fill the troops with the enthusiasm of that period, and incite them to fresh victories. I saw him with a smiling countenance making the most confident promises of victory out of his carriage window to the surrounding crowd; he then drove off amid the loud huzzas of the assembled multitude. The soldiers were singing jovial songs, and rejoicing that at last they were to be led against the enemy; everywhere were to be seen the stragglers and others rushing to join the army. The noise died away after leaving Potsdam—an unusual stillness prevailed, and the fine summer weather soon banished from my thoughts all save the objects and expectations which more immediately concerned myself.”

Music and merriment were not to last for long. All too soon sunshine turned to rain, pride of race to national disaster. But it taught the Prussians a lesson they never forgot, even if they were slow to learn, and the full fruits of it were reaped on the field of Waterloo nine years later.

At first Napoleon felt confident that the military preparations in Prussia were nothing but bluff, and although war was decided upon at Berlin on the 7th August 1806, and an ultimatum sent to Paris on the 25th September, it was not until the 7th October that Napoleon heard of it, for he was then with his army. By the following day many of his troops had crossed the frontier. His fighting force numbered, in all, some 190,000 men, that of his opponents some 40,000 less, under the chief command of the Duke of Brunswick, a veteran over seventy years of age who had seen service in the wars of the Warrior King. With the French eagles marched many soldiers of the Confederation, evidence of the value of the policy of Napoleon to surround himself with vassal states. It was a somewhat one-sided bargain, for it was considerably more likely that he, in pursuing his aggressive projects, would call upon his allies more frequently than they upon him. Prussia was aided by Russia in the later stages of the campaign, for it was not until after the battle of Jena that the Czar’s slow-moving forces were available. Saxony completed what might have been a most formidable triple alliance.

The Prussian general’s great hope was that he might be able to cut off Napoleon’s communications with France, but he was far too cumbersome in his movements to catch so nimble an adversary. The Emperor divined the plan, gave orders for an immediate concentration of his troops, and turned the tables by threatening the Prussian communications with Berlin. To Bernadotte was given the task of clearing the way for the main army. On the 9th October an affray took place between Saalburg and Schleiz, where there was an extensive wood, and the Prussians were forced to give way after a lengthy resistance. The French afterwards marched to Schleiz and carried the place. Murat, who had put himself in possession of Saalburg on the previous day, also accomplished much difficult work. More important was the action fought near Saalfeld between Lannes and Suchet and Prince Louis Ferdinand of Prussia, in which the young prince—he was but thirty-three years of age—lost his life while fighting against desperate odds. The infantry he commanded fell into disorder, and soon got altogether out of hand. The Prince had now but five squadrons of cavalry on which he could rely, and he determined to die rather than surrender. He gave the order to charge, was wounded in several places, and at last fell from his horse, the victim of a fatal sword-thrust from a hussar. He certainly exhibited the contempt for death which Napoleon recommended to his chasseurs about this time. “My lads,” said he, “you must not fear death; when soldiers brave death, they drive him into the enemy’s ranks.”

The campaign was speedily decided. While the Emperor was closing upon the allied forces concentrated near Weimar and Jena under the King and Prince Hohenlohe respectively, a very foolish movement was decided upon. A large portion of the Prussian forces were detached for the relief of Naumburg, leaving but 47,000 men to face the French should they appear. The unexpected happened; for on the same day the Landgrafenberg, a steep hill whose summit, well-nigh inaccessible but commanding a magnificent bird’s-eye view of the army Napoleon had marked for destruction, was unexpectedly occupied by the French. Almost superhuman exertion was required to haul up the heavy artillery so that it might be placed in the most advantageous positions for the coming conflict. Napoleon invariably discarded his trappings of state during a campaign and assumed the duties of a common soldier when necessity demanded, as on this occasion. He showed himself ready and willing to take his share in what the troops called “the dirty work.” He laid mines for the blasting of rocks which blocked progress up the rugged heights, tugged at the ropes by which the cannon were hauled to the wind-swept ridge, and did not retire to his tent until he was perfectly satisfied in his own mind that nothing had been left undone which might contribute to the discomfiture of the enemy.

The story is told by Marbot, who, if he tells the truth, performed prodigies of valour worthy of D’Artagnan himself. A village priest pointed out the path which enabled the French troops to ascend the Landgrafenberg. “Up this path,” the genial Marshal relates, “he led some officers of the staff and a company of voltigeurs. The Prussians, believing it to be impracticable, had neglected to guard it. Napoleon judged otherwise, and, on the report of the officers, went himself to see it, accompanied by Marshal Lannes and guided by the curé. He found that between the top of the path and the plain occupied by the enemy, there was a small rocky platform; and on this he determined to assemble a part of his troops, who should sally forth from it, as from a citadel, to attack the Prussians. For any one except Napoleon, commanding Frenchmen, the task would have been impossible; but he, sending to the engineers and artillery for four thousand pioneer’s tools, set the infantry to work to widen and level the path, the battalions taking it in turn, each one for an hour, and as it finished its task, advancing in silence and forming on the top of the hill.... The nights were very long at this season of the year, and there was plenty of time to make the path practicable not only for columns of infantry, but for artillery and ammunition waggons; so that before daybreak the troops were massed on the Landgrafenberg. The term massed was never more correct, for the breasts of the men in each regiment were almost touching the backs of those in front of them. But the troops were so well disciplined that, in spite of the darkness and the packing of more than 40,000 men on the narrow platform, there was not the least disorder, and although the enemy who were occupying Cospoda and Closevitz were only half a cannon-shot off, they perceived nothing.”

In the plain below the flaming bivouac fires winked and blinked like watch-dogs at the Prussian soldiers. Some had already taken an unconscious farewell of the stars as their weary eyelids closed upon a scene of natural beauty marred by the stacks of arms, parks of artillery and baggage waggons, which told of imminent strife and bloodshed.

At four o’clock in the morning, ere the faintest streak of dawn had pierced the sky, the French camp was astir, and Napoleon with it. Had a dragon breathing fire and brimstone presented itself on the field of Jena Prince Hohenlohe could not have been more surprised than when the French advance guard suddenly appeared out of a heavy, rolling, autumn mist. The death-dealing guns began their work, the cavalry and infantry on either side fought with desperation, and the battle inclined first to the one side, then to the other. The Prussian troops showed that notwithstanding long years of inaction there was still some of the blood and iron of Unser Fritz left in them; but before the reserve of 20,000 under Rüchel, for whom Hohenlohe had sent, came up, he had been obliged to write a second despatch urging haste, and confiding the news that the French cavalry “has driven into one confused mass the infantry, cavalry, and artillery.” When the reserve appeared on the field the addition of so large a number of men tended to steady the Prussians, and it was on seeing them that an impetuous young French officer, noting the effect, shouted: “Forward! Forward!” to the Imperial Guard, which had not yet been used. “How now?” asked Napoleon. “What beardless boy is this who ventures to counsel his Emperor? Let him wait till he has commanded in thirty pitched battles before he proffers his advice!”

The day was definitely decided by a magnificent cavalry charge led by Murat, which caused a rout that only ended at Weimar, the home of the immortal Goethe, six leagues away.
