History: The Garrison Regiment of Riga in the Swedish dominion of Livonia, modern Latvia. The regiment was formed from various regiments of horse stationed in Riga in 1656 and as the name suggests was one of many regiments formed for the defense of fortresses across the empire. Garrison regiments usually consisted of around 1,000 men. In 1686, the regiment was re-organized into infantry and remained in Riga during the Great Northern War.
 
It participated in the Siege of Riga by the outbreak of the war in 1700 and successfully repulsed the Saxons until the main Swedish army arrived to sweep the remaining forces away in the Battle of Riga which left the Saxon forces defeated. The regiment also took part in the Crossing of the Düna River near Riga the following year when the Swedes was in pursuit of king Augustus II the Strong of the Polish–Lithuanian Commonwealth and Saxony. The crossing was a major success and the Polish and Saxon troops were quickly retreated. The regiment got captured in Riga in 1710 by the Russians when the city finally fell following the failed Swedish invasion of the Russian Empire the year before.
