It will be remembered that Breslau, whose inhabitants were mainly Protestant, and which was one of the so-called free cities of Germany, was surrendered to Frederick under peculiar conditions. It was to remain, in its internal government, in all respects exactly as it had been, with the simple exception that it was to recognize the sovereignty of Prussia instead of that of Austria. Its strict neutrality was to be respected. It was to be protected by its own garrison. No Prussian soldier could enter with any weapons but side-arms. The king himself, in entering the city, could be accompanied only by thirty guards.The enemy threw such a multitude of bombs and red-hot balls into the city that by nine oclock in the morning it burned, with great fury, in three different places. The fire could not be extinguished, as the houses were closely built, and the streets narrow. The air appeared like a shower of fiery rain and hail. The surprised inhabitants had not time to think of any thing but of saving their lives by getting into the open fields.
