All the Princes of the Royal Family wear the _Prussian_ Order, _viz._ that of the Black Eagle; and receive it as soon as they are born. ’Tis an Orange Ribband, to which is appendant a Cross enamel’d with blue, resembling the Cross of _Malta_. A Star of Silver is embroider’d on the Coat; and in the middle of it is an Orange Escutcheon, over which is a black Eagle crown’d with Wings display’d, holding in one of its Talons a Crown of Laurel, and in the other a Thunder-bolt, with the Motto, SUUM CUIQUE, in Letters of Gold. This Order was instituted by _Frederic_ I. the sixth of _January_ 1701, _O. S._ on account of his Coronation at _Koningsberg_. He call’d it the Order of the Black Eagle, because a Black Eagle forms the Arms of _Prussia_; and he chose an Orange Ribband, in memory of the Electress his Mother, who was a Princess of _Orange_; in Right of whom he pretends to be next Heir to _William_ III. King of _England_, and Prince of _Orange_. The Princes of the Royal Family are not exempt from passing thro’ the Degrees of military Service; and ’tis not here as in other places, where they have Regiments and Governments as soon as they are born. The King will have them to know how to obey, before they come to command; and ’tis an Encouragement to the Officers to find themselves so far honour’d, as to be on a Par in the Service, with those who are born to be their Sovereigns. The Prince Royal has a Regiment of Horse[13]. M. _de Lopel_[14], a Major-General, commanded that Regiment formerly, but the King preferring him to the Government of _Custrin_, this Regiment has for Colonel M. _de Wreech_, a Person of a good Family in the new Marquisate. His Father, who was one of the King’s Lieutenant-Generals, had serv’d the late Elector _Frederic-William_, the late King, and his present Majesty. M. _de Wreech_, whom I am speaking of, was, at his return from his Travels, appointed by the late King a Gentleman of his Bed-chamber: After that Prince’s Death, his present Majesty enter’d him into his Service, and gave him a Troop of Horse. This Gentleman distinguished himself greatly in 1708, at the Battle of _Audenarde_; where he was _Aid de Camp_ to the Marshal _de Natzmer_, then General of the Cavalry: He had a Horse kill’d under him, and was taken Prisoner; but the Enemy in their Flight not watching him very strictly, he found means to get off when the Night came and put an end to the Battle. He lay hid in a Ditch till next day, in danger every moment of being knock’d on the head by our own Men; but when the Day broke, he rejoin’d his General, who had received a slight Wound in the Head. M. _de Wreech_ is one of the richest Subjects the King has; but he is worthy of his Fortune, and uses it like a Man of Quality. He is certainly a valuable Gentleman, has a noble Soul, and Sense and Knowledge enough to capacitate him to serve his King and Country both in Peace and War.
