In 1740, the French King Louis XV granted his Swedish-led forces the title of Royal Swedish Regiment, for which it received the same privileges as all royal regiments, including the protection of the king, new flags, and ordinance. Louis XV acted to fulfill a request of King Fredrik I of Sweden and to demonstrate his satisfaction with the great value shown by the regiment in battle. This intriguing book traces the history of this storied regiment throughout its service, including during the American War of Independence, and up to the time of the French Revolution of 1789.
