Visit of the German Prince Imperial (Crown Prince of Prussia) to Mont Val?rien, [France], 1871. Franco-Prussian War: The surrender of Paris...The King of Prussia, or, as he must now be styled, the German Emperor, with Count Moltke and others, came next day to see the fortress; so did the German Prince Imperial (Crown Prince of Prussia), with General Blumenthal and his staff. They inspected the great guns with minute attention, especially the one named Sainte Val?rie, which was slung by chains, in a peculiar fashion, within an iron framework rising above its carriage. From "Illustrated London News", 1871.
