“ After the final fall of Napoleon he served on the staff of the army of occupation in France and was for some months military governor of Paris. He spent a part of his time on the Rhine in survey work, and was employed by Frederick William III. in various diplomatic missions. In 1821 he became chief of the general staff at Berlin, and though he has been accused of indulging his taste for topographical work at the expense of training for war, his work was not wasted, for he gave an excellent organization to the general staff, and executed elaborate and useful surveys. ”

“ He took a prominent part in the military and civil history of Prussia, and from 1838–1847 was governor of Berlin. Failing health compelled his retirement in the latter year, and he died on the 16th of January 1851, at his estate of Ringhofen near Berlin. ”
