At the Pss. Ferdinand’s at Bellevue I made acquaintance with Mde. du Néal, whom I liked extremely. We had some thoughts of going to Rheinsberg, the residence of Prince Henry;[148] she fortified us in the idea, and offered letters to her two nieces, who compose part of his Court. Mr. Bruce, Ld. Elgin’s brother, lodged in our hotel; he is going back to India by way of Constantinople, where he means to visit his brother; he dined with us. Ld. H. invited him out of good nature, from hearing he was solitary and unacquainted with the society of Berlin. Baron Schack, a _gens d’armes_ [_sic_], to whom we had been civil in London, was at Berlin; he was too much occupied with love, gambling, and military duties to be of much service to us. [Sidenote: RHEINSBERG] Determined to go to Rheinsberg. Set off at 12 o’clock at night on Wednesday, 17th August. Left Charles and Drew: they were to go to Potsdam. We were to join them there. Ld. Duncannon and myself went in the open carriage; Ld. H., Marsh, and Hortense in the chaise; ye coach and three servants left with Drew and Charles. As soon as we reached Rheinsberg on Thursday eve. we went to the inn, and sent out letters to the ladies and Count Brühl, one of the Chamberlains. They were all at the _spectacle_, but the gentlemen came out and invited us from the Prince to lodge in his _château_ and to join him at the play. The latter was rather inconvenient as we had no clothes with us (the other carriage being behind), besides that we had travelled all night, and were dinnerless. Those difficulties were soon settled, and we got in time to see the _Petite Pièce_. The Prince is one of the most remarkable men in Germany; he distinguished himself in his brother’s wars as a consummate general, and may boast of having done that which is almost unparalleled, of having put a French army to flight; at Rosbach they fled before him. He is 75 years old, and possesses a strength and vivacity of intellect equal to what he formerly enjoyed. He is a Frenchman in his heart, he abhors everything German; cannot speak it. He has a delightful French comedy; his _troupe_ of comedians is really good, the theatre remarkably pretty. I never passed five days more delightfully than under his hospitable roof.
