The Prussian troops, meeting with no opposition, spread over the country, and a strong division reached Weichau on Saturday, the 17th. There they spent Sunday in rest. Frederick was anxious to win to his cause the Protestant population. He consequently favored their religious institutions, and ordered that Protestant worship should be held in the villages which he occupied, and where there was no Protestant church edifice, one part of the day in the Catholic churches. This plan he continued through the campaign, much to the gratification of the chaplains of his regiments and the Protestant community in Silesia. Though the Austrian government had not been particularly oppressive to the Protestants, still it leaned decidedly against what it deemed heresy. The Jesuits, favored by the governmental officials, were unwearied in their endeavors to promote the interests of their Church. Frederick, by allowing the impression to be spread abroad that he was the champion of Protestantism, was enabled to secure the sympathies of quite a strong party in Silesia in his favor. It is said that two thirds of the inhabitants of Silesia were Protestants, and therefore favorable to Frederick. [Illustration: THE MARCH INTO SILESIA.] In the suburbs of Glogau there was a Protestant church which Count Wallis deemed it a military necessity to order to be burned down, lest it should protect the Prussians in their attack. “The Prussians,” said Wallis, “will make a block-house of it.” The Protestants pleaded earnestly for a brief respite, and sent a delegation to Frederick to intercede for the safety of their church. The king very courteously, and with shrewd policy, replied, “You are the first who have asked any favor of me on Silesian ground. Your request shall be granted.” Immediately he sent a polite note to Count Wallis, assuring him that the attack, if attack were necessary, should be made on the other side of the city, so that no military advantage could be taken of the church. This popular act resounded widely not only through the Protestant community of Silesia, but throughout Europe. Monday morning, December 19th, the army was again on the move, now spread out into a length of nearly fifteen miles, and even more than that in breadth. Concentration was unnecessary, as there was no foe to be encountered. The occupation of this wide area enabled Frederick to take advantage of good roads, and also to obtain abundance of supplies. Their advance led them in a southerly direction, up the western banks of the Oder, which stream here runs nearly north.
