“ From 1836 to 1848 de Broglie held almost completely aloof from politics, to which his scholarly temperament little inclined him, a disinclination strengthened by the death of his wife on the 22nd of September 1838. His friendship for Guizot, however, induced him to accept a temporary mission in 1845, and in 1847 to go as French ambassador to London. The revolution of 1848 was a great blow to him, for he realized that it meant the final ruin of the Liberal monarchy—in his view the political system best suited to France. ”

“ He was governor-general of Alsace when Frederick the Great paid a secret visit to Strassburg (1740) . In 1742 de Broglie was appointed to command the French army in Germany, but such powers as he had possessed were failing him, and he had always been the “man of small means,” safe and cautious, but lacking in elasticity and daring. The only success obtained was in the action of Sahay (25th May 1742) , for which he was made a duke. He returned to France in 1743, and died two years later. ”

“ But for the sympathy of Great Britain under Palmerston, the July monarchy would have been completely isolated in Europe; and this sympathy the aggressive policy of France in Belgium and on the Mediterranean coast of Africa had been in danger of alienating. The Belgian crisis had been settled, so far as the two powers were concerned, before de Broglie took office ”

“ He adopted revolutionary opinions, served with Lafayette and Rochambeau in America, was a member of the Jacobin Club, and sat in the Constituent Assembly, constantly voting on the Liberal side. He served as chief of the staff to the Republican army on the Rhine; but in the Terror he was denounced, arrested and executed at Paris on the 27th of June 1794. His dying admonition to his little son was to remain faithful to the principles of the Revolution, however unjust and ungrateful. ”

“ In the campaign of 1734 he was one of the chief commanders on the French side, and he fought the battles of Parma and Guastalla. A famous episode was his narrow personal escape when his quarters on the Secchia were raided by the enemy on the night of the 14th of September 1734. In 1735 he directed a war of positions with credit, but he was soon replaced by Marshal de Noailles. ”
