I would like to say thank you to Dan Schoor for remark he made about Saxon mounted Guard units in my post about Polish-Saxon BO at Riga. He wrote that Schuster & Francke’s data about Saxon Guard units in my post was wrong (now it’s updated). He provided me with a link to Minckwitz’s book (Minckwitz, August von. "Die ersten kursachschen Leibwachen zu Ros und zu Fus und ihre Geschichte". Dresden, 1894).
Ancient Saxon Corps of mounted Leib-guard (Leib-Garde zu Ross) since 1681 also was called Trabanten (Trabanten-Leibgarde zu Ross). The term Garde du Corps was first used in 1697, but other names were also in use. Since January 1, 1677 it consisted of 4 squadrons.
In 1698-99 the fourth squadron of the Trabanten-Leibgarde was converted into 3 new Corps: Grand Mousquetaires, Karabiniers and Grenadiers a Cheval. (s. 50). Evidently each of them was of a company strength.
The fourth squadron was re-established by 1699. On May 1, 1699 the Garde du Corps consisted of 4 squadrons, each of 3 coys or brigades. Squadrons differed each other by a color of horses: white in the 1st (Obristen prince Alexander Sobieski), black in 2nd (Obrist-lieutenant von Bensig), dark-brown in 3rd (Obrist-wachtmeister Senge) & light-brown in 4th (Obrist-wachtmeister von Rothe). Each squadron consisted of: 3 Rittmeister, 3 Lieutenant, 1 Cornet, 1 Quartiermeister, 1 Feldscheer, 3 Wachtmeister, 9 Korporale, 6 Trompeter, 1 Fahnen-Sattler, 1 Fahnen-Schmeid, 135 (increased to 150 on May 1, 1700) Trabantans. Corps staff included 1 Adjutant, 1 Ober-Auditeur, 1 Feldprediger, 1 Pauker, 1 Profos.
In 1700 new corps commander (and a commander of 1st squadron) became General-Lieutenant Carl Gustav Jordan.
In July 1700 the Corps arrived to Riga.
