In 1794, he was sent as Envoy-extraordinary to Berlin to remind King Frederick William II of his obligations to Holland, a service in which Lord Malmesbury the ambassador commended him for his tact.

He was materially contributed to the creation of the Third Coalition, and reported its collapse following the Battle of Austerlitz (2 December 1805), a dispatch that is said to have hastened the death of William Pitt the Younger (23 January 1806).
