Excerpt
It was a fine, warm day in May, 1812. The world was groaning under the yoke of Napoleon's tyranny. As a consolation for the hopeless year, came the laughing spring. Fields, forests, and meadows, were clad in beautiful verdure; flowers were blooming, and birds were singing everywhere”even at Charlottenburg, which King Frederick William formerly delighted to call his "pleasure palace," but which now was his house of mourning. At Charlottenburg, Frederick William had spent many and happy spring days with Queen Louisa; and when she was with him at this country-seat, it was indeed a pleasure palace.
