If ever the ruler of a nation is to be justified for going to war when his country is not actually invaded, it was doubtless Gustavus Adolphus. Had he withheld his aid, the probability is that all Germany would have succumbed to the Austrian emperor, and have been incorporated with his empire; and not only Germany, but Denmark and Sweden. The Protestant religion would have been suppressed in northern Germany, as it was in France by Louis XIV. There would have been no Protestant country in Europe, but England, and perhaps Holland. A united German Empire, with the restoration of the Catholic religion, would have been a most dangerous power,--much more so than at the present day. Some there are, doubtless, who would condemn Gustavus for the invasion of Germany, and think he ought to have stayed at home and let his unfortunate neighbors take care of themselves the best way they could. Perhaps the peace societies would take this ground, and the apostles of thrift and material prosperity. But I confess, when I see a man like the King of Sweden, with all the temptations of luxury and ease, encountering all sorts of perils and fatigues,--yea, offering up his life in battle in order to emancipate suffering humanity,--then every generous impulse and every dictate of enlightened reason urge me to add my praises with those of past generations in honor of such exalted heroism.
According to the authors of those times, signs and prodigies appeared, to warn mankind of the sanguinary struggle which was now to take place. "In the dead of night, on wild heaths, in solitary valleys, the clang of arms was heard. Armies were seen encountering each other in the heavens, marshalled by aërial leaders, while monstrous births, mock suns, and showers of fire filled the minds of the superstitious with fear and dread. It would be puerile to believe these statements, yet if the stupendous framework of external nature ever could exhibit sympathy with the brief calamities of man, it may well be supposed to have been displayed when one of the fairest portions of the earth was again to be ravaged with fire and sword; and when the melancholy lesson, so often exemplified before, was to receive still further confirmation,--that of all the evils with which Divine wisdom permits this world to be visited, none can be compared to those which the wrath of man is so often eager to inflict upon his fellows."
I need not detail the various campaigns of the Swedish hero, his marchings and counter-marchings, his sieges and battles and victories, until the power of Austria was humbled and northern Germany was delivered. The history of all war is the same. There is no variety except to the eye of a military man. Military history is a dreary record of dangers, sufferings, mistakes, and crimes; occasionally it is relieved by brilliant feats of courage and genius, which create enthusiastic admiration, but generally it is monotonous. It has but little interest except to contemporaries. Who now reads the details of our last great war? Who has not almost forgotten the names of its ordinary generals? How sickening the description of the Crusades! The mind cannot dwell on the conflagrations, the massacres, the starvations, the desolations, of an invaded country. Few even read a description of the famous battles of the world, which decided the fate of nations. When battles and marches are actually taking place, and all is uncertainty, then there is a vivid curiosity to learn immediate results; but when wars are ended, we forget the intense excitements which we may have felt when they were taking place. We gaze with eager interest on a game of football, but when it is ended we care but little for the victors. It is only when the remote consequences of great wars are traced by philosophical historians, revealing the ways of Providence, retribution, and eternal justice, that interest is enkindled. No book to me is more dreary and uninteresting than the campaigns of Frederic II., though painted by the hand of one of the greatest masters of modern times. Even interest in the details of the battles of Napoleon is absorbed in the interest we feel in the man,--how he was driven hither and thither by the Providence he ignored, and made to point a moral to an immortal tale. All we care about the histories of wars is the general results, and the principles to be deduced as they bear on the cause of civilization.
It was fortunate for the fame and the cause of Gustavus that at the very outset of his career, when he landed in Pomerania, with his small army of twenty thousand men, the Emperor had been prevailed upon by a pressure he could not resist, and the intrigues of all the German princes, to dispense with the services of Wallenstein. Spain, France, Bavaria,--the whole Electoral College, Catholic as well as Protestant,--clamored for the discharge of the most unscrupulous general of modern times. He was detested and feared by everybody. Humanity shed tears over his exactions and cruelties, while general fears were aroused that his influence was dangerous to the public peace. Most people supposed that the war was virtually ended, and that he was therefore no longer needed.
Loath was Ferdinand to part with the man to whom he was indebted for the establishment of his throne; and it seems he was also personally attached to him. Long did he resist expostulations and threats. He felt as poor Ganganelli felt when called upon by the Bourbon courts of Europe to annul the charter of the Jesuits. Wallenstein would probably have been retained by Ferdinand, had this been possible; but the Emperor was forced to yield to overwhelming importunities. So the dismissal of the general was decreed at the diet of Worms, and a messenger of the Emperor delivered to the haughty victor the decree of his sovereign.
Wallenstein was then at the head of one hundred thousand men. Would he obey the order? Would he retire to private life? Ambitious and unscrupulous as he was, he knew that no one, however powerful, could resist an authority universally conceded to be supreme and legitimate. It was like the recall of a proconsul by the Roman Emperor and Senate: he could resist for a time, but resistance meant ultimate ruin. He also knew that he would be recalled, for he was necessary to the Emperor. He anticipated the successes of Gustavus. He was not prepared to be a traitor. He would wait his time.
So he resigned his command without a moment's hesitation, and with apparent cheerfulness. He even loaded the messenger with costly gifts. He appeared happy to be relieved from labor and responsibility, and retired at once to his vast Bohemian estates to pursue his favorite studies in the science of the stars, to enshroud himself in mystery and gloom, and dazzle his countrymen by the splendor of his life. "His table was never furnished with less than one hundred covers; none but a noble of ancient family was intrusted with the office of superintending his household; an armed guard of fifty men waited in his antechamber; the ramparts of his castle were lined with sentinels; six barons and as many knights constantly attended on his person; sixty pages were trained and supported in his palace, which was decorated with all the wonders of art, and almost realized the fictions of Eastern luxury." In this splendid retirement Wallenstein brooded on his wrongs, and waited for the future.
The dismissal of this able general was a great mistake on the part of the Emperor. There were left no generals capable of opposing Gustavus. The supreme command had devolved on Tilly, able but bigoted, and best known for his remorseless cruelty when Magdeburg was taken by assault,--the direst tragedy of the war. This city was one of the first to welcome the invasion of the King of Sweden, and also to adopt the Protestant religion. It was the most prosperous city in northern Germany; one of the richest and most populous. Against this mercantile fortress Tilly directed all his energies, for he detested the spirit of its people. It was closely invested by the imperial troops, and fell before Gustavus could advance to relieve it. It was neglected by the electors of Saxony and Brandenburg, who were timid and pusillanimous, and it was lulled into false security by its strong position and defences. Not sufficient preparation for defence had been made by the citizens, who trusted to its strong walls, and knew that Gustavus was advancing to relieve it. But unexpectedly it was assaulted in the most daring and desperate manner, and all was lost. On a Sabbath morning, the sudden toll of alarm bells, the roar of artillery, the roll of drums beating to quarter, and the piercing cries of women and children, mingled with the shouts and execrations of brutal and victorious soldiers, announced the fate of Magdeburg. Forty thousand people--men, women, and children--were inhumanly butchered, without necessity, quarter, compassion, or remorse. So cold and hard is war! This was the saddest massacre in the history of Germany, and one of the greatest crimes that a successful general ever committed. History has no language, and painting no colors to depict the horrors of that dreadful scene; and the interval of more than two hundred years has not weakened the impression of its horrors. The sack of Magdeburg stands out in the annals of war like the siege of Tyre and the fall of Jerusalem.
But it roused the Protestants as from a trance. It united them, as the massacre of St. Bartholomew united the Huguenots. They marched under the standard of Gustavus with the same enthusiasm that the Huguenots showed under Henry IV. at the battle of Ivry. There was now no limit to the successes of the heroic Swede. The decisive battle of Leipsic, the passage of the Lech, the defence of Nuremberg, and the great final victory at Lutzen raised the military fame of Gustavus to a height unknown since Hannibal led his armies over the Alps, or Caesar encountered the patrician hosts at the battle of Pharsalia. No victories were ever more brilliant than his; and they not only gave him a deathless fame, but broke forever the Austrian fetters. His reputation as a general was fairly earned. He ranks with Condé, Henry IV., Frederic the Great, Marlborough, and Wellington; not, perhaps, with Alexander, Caesar, and Napoleon,--those phenomena of military genius, the exalted trio who shine amid the glories of the battlefield, as Homer, Dante, and Shakspeare loom up in fame above other immortal poets.
In two years from the landing of Gustavus Adolphus on the island of Ruden, near the southern extremity of the Baltic, he expelled a triumphant enemy from Pomerania, traversed the banks of the Oder, overran the Duchy of Mecklenburg, ascended the Elbe, delivered Saxony from the armies of Tilly, crossed the Thuringian forest, entered Frankfort in triumph, restored the Palatinate to its lawful sovereign, took possession of some of the strongest fortresses on the Rhine, overran Bavaria, occupied its capital, crossed the Danube, and then returned to Saxony, to offer up his life on the plains of Lutzen. There, on that memorable battlefield, where the descending sun of victory in later times shed a delusive gleam on the eagles of Napoleon before his irremediable ruin, did Gustavus encounter the great antagonist of German liberties, whom the necessities of the Emperor had summoned from retirement. Wallenstein once more commanded the imperial armies, but only on conditions which made him virtually independent of his master. He was generalissimo, with almost unlimited authority, so long as the war should last; and the Emperor agreed to remove neither the general himself nor his officers, and gave him principalities and spoils indefinitely. He was the most powerful subject in Europe, and the greatest general next to Gustavus. I read of no French or English general who has been armed with such authority. Cromwell and Napoleon took it; it was not conferred by legitimate and supreme power. Had Wallenstein been successful to the end, he might have grasped the imperial sceptre. Had Gustavus lived, he might have been the dictator of Germany.
