Notwithstanding these sentiments, the king sent throughout Silesia a supply of sixty Protestant preachers, ordained especially for the work. Though Frederick himself did not wish to live in accordance with the teachings of Jesus Christ, it is very evident that he did not fear the influence of that Gospel upon his Silesian subjects. Very wisely the Protestant preachers were directed carefully to avoid giving any offense to the Catholics. They were to preach in barns and town-halls in places where there was no Protestant church. The salary of each was one hundred and fifty dollars a year, probably with rations. They were all placed under the general superintendence of one of the army chaplains.

Every day it became more clear that Maria Theresa was resolved not to part with one inch of her territory, and that the Austrian court was thoroughly roused in its determination to drive the intrusive Prussians out of Silesia. Though Frederick had no scruples of conscience to prevent him from seizing a portion of the domains of Maria Theresa, his astonishment and indignation were alike aroused by the rumor that England, Poland, and Russia were contemplating the dismemberment of his realms. An army of thirty-six thousand men, under the old Duke Leopold of Dessau,[51] was immediately dispatched by Frederick to Götten, on the frontiers of Hanover, to seize upon that Continental possession of the King of England upon the slightest indication of a hostile movement. George II. was greatly alarmed by this menace.

Frederick found himself plunged into the midst of difficulties and perils which exacted to the utmost his energies both of body and of mind. Every moment was occupied in strengthening his posts, collecting magazines, recruiting his forces, and planning to circumvent the foe. From the calm of Reinsberg he found himself suddenly tossed by the surges of one of the most terrible tempests of conflict which a mortal ever encountered. Through night and storm, almost without sleep and without food, drenched and chilled, he was galloping over the hills and through the valleys, climbing the steeples, fording the streams, wading the morasses, involved in a struggle which now threatened even the crown which he had so recently placed upon his brow. Had Frederick alone suffered, but few tears of sympathy would have been shed in his behalf; but his ambition had stirred up a conflict which was soon to fill all Europe with the groans of the dying, the tears of the widow, the wailings of the orphan.

Frederick deemed it of great importance to gain immediate possession of Glogau. It was bravely defended by the Austrian commander, Count Wallis, and there was hourly danger that an Austrian army might appear for its relief. Frederick, in the intensity of his anxiety, as he hurried from post to post, wrote from every stopping-place to young Leopold, whom he had left in command of the siege, urging him immediately to open the trenches, concentrate the fire of his batteries, and to carry the place by storm. “I have clear intelligence,” he wrote, “that troops are actually on the way for the rescue of Glogau.” Each note was more imperative than the succeeding one. On the 6th of March he wrote from Ohlau:

“I am certainly informed that the enemy will make some attempt. I hereby, with all distinctness, command that, so soon as the petards are come, you attack Glogau. And you must make your dispositions for more than one attack, so that if one fail the other shall certainly succeed. I hope you will put off no longer. Otherwise the blame of all the mischief that might arise out of longer delay must lie on you alone.”

On the 8th of March Leopold summoned all his generals at noon, and informed them that Glogau, at all hazards, must be taken that very night. The most minute directions were given to each one. There were to be three attacks—one up the river on its left bank, one down the river on its right bank, and one on the land side perpendicular to the other two. The moment the clock on the big steeple in Glogau should give the first stroke of midnight, the three columns were to start. Before the last stroke should be given they were all to be upon the silent, rapid advance.

Count Wallis, who was intrusted with the defense of the place, had a garrison of about a thousand men, with fifty-eight heavy guns and several mortars, and a large amount of ammunition. Glogau was in the latitude of fifty-two, nearly six degrees north of Quebec. It was a cold wintry night. The ground was covered with snow. Water had been thrown upon the glacis, so that it was slippery with ice. Prince Leopold in person led one of the columns. The sentinels upon the walls were not alarmed until three impetuous columns, like concentrating tornadoes, were sweeping down upon them. They shouted “To arms!” The soldiers, roused from sleep, rushed to their guns. Their lightning flashes were instantly followed by war’s deepest thunders, as discharge followed discharge in rapid succession.

But the assailants were already so near the walls that the shot passed harmlessly over their heads. Without firing a gun or uttering a sound, these well-drilled soldiers of Frederick William hewed down the palisades, tore out the chevaux-de-frise, and clambered over the glacis. With axe and petard they burst open the gates and surged into the city.

In one short hour the gallant deed was done. But ten of the assailants were killed and forty-eight wounded. The loss of the Austrians was more severe. The whole garrison, one thousand sixty-five in number, and their materiel of war, consisting of fifty brass cannons, a large amount of ammunition, and the military chest, containing thirty-two thousand florins, fell into the hands of the victors. To the inhabitants of Glogau it was a matter of very little moment whether the Austrian or the Prussian banner floated over their citadel. Neither party paid much more regard to the rights of the people than they did to those of the mules and the horses.

But to Frederick the importance of the achievement was very great. The exploit was justly ascribed to his general direction. Thus he obtained a taste of that military renown which he had so greatly coveted. The king was, at this time, at his head-quarters at Schweidnitz, about one hundred and twenty miles from Glogau. A courier, dispatched immediately from the captured town, communicated to him, at five o’clock in the afternoon, the glad tidings of the brilliant victory.
