In the revolt of the Tyrolese against the Bavarian yoke imposed on them by the French, his heart went out to the gallant insurgents. He pensioned a son of the patriot Speckbacher, and condoled with Hofer's wife on the execution of her husband. Napoleon's indignation knew no bounds. "This prince," he declared, "shall never reign in Bavaria!" He destined the crown for Eugène Beauharnais, or one of his children.
But it was Louis's policy that triumphed in 1813. With delight he beheld his father desert the sinking ship of France, and from Salzburg (then belonging to Bavaria) he issued a proclamation, urging all the German people to rise against the common oppressor. Wrede, with a Bavarian army, threw himself across the path of the retreating French at Hanau, to find that the wounded eagle's talons could still snatch a bloody victory. In the campaigns of 1814 and 1815, Louis took no active part. His father dreaded that he might fall into the hands of Napoleon, who regarded him with intense hatred. The Prince had to be content with the part of Tyrtaeus, and in odes, not deficient in merit, stirred the patriotic feelings of his countrymen.
After Waterloo he sheathed the sword that he had wielded reluctantly, but not ingloriously. "I was never a general," he said, "but a soldier, yes--with all my heart." He was now free to devote himself to matters which more strongly, perhaps, appealed to him. At Vienna and London he watched over the interests of the arts. He pleaded (and not unsuccessfully) for the restitution of the artistic treasures Napoleon had carried off, and wrote on the subject of the Elgin marbles with judgment and critical acumen. He sought the acquaintance of the brilliant and the learned, presiding over a _côterie_ of painters, sculptors, and _literati_. The winters of 1817-8 and 1820-1 he spent in the Eternal City, residing at the Bavarian Embassy or at the Villa Malta on the Pincio. He knew Canova and Thorwaldsen, and laid the foundations of his firm and life-long intimacy with the sculptor, Wagner. On the Neue Pinakothek at Munich is a picture by Catel, representing one of those joyous and scholarly _réunions_ in which Louis delighted. He is shown seated at a table in a humble _osteria_ on the Ripa Grande, in the company of Thorwaldsen, Wagner, the artists Veit, Von Schnorr, and Catel himself, the architect Von Klenze, Professor Ringseis, Count Seinsheim, and Colonel von Gumppenberg. It was in such company, and beneath the blue sky of Italy, that "the most German of the Germans" was happiest. His æsthetic faculties were altogether exotic. His style of literary composition is compared by an English writer to a dislocation of all the limbs of a human body.
