In 1711 a Norwegian Army was raised to invade and recapture the former Norwegian province of Bohuslen under the leadership of Lieutenant General Caspar Hausmann . In parallel a strong fleet was to provide protection and transportation to seaward ; Frederick IV committed to providing such a force under Vice Admiral Sehested in June 1711 . In August , the Norwegian army marched into Bohuslen . But by late summer Vice Admiral Sehested ’ s fleet had not appeared offshore , having been ordered by Frederick IV to return to Baltic waters . Without naval support , the Norwegian Army was forced to return to Norway . In April 1712 during the Great Northern War he was promoted to commander - in - chief ( the commanding General ) of the Army in Norway ; he served in this position until January 1716 . Gjerset indicates that , " General Hausmann , the commander - in - chief of the army , and the military member of the " Slottsloven " , who had proven himself both able and conscientious , and had brought the army into a high state of readiness , was dismissed shortly before the war ( combat in Norway ) broke out because the government feared lest his warlike spirit should lead him to act with too much haste . " The Norwegian army , which he played an instrumental role in building , successfully repelled Swedish campaigns in both 1716 and 1718 . Awards . Hausmann was awarded a knighthood in the Order of the Dannebrog 1709 and received the title " geheimeråd " ( one of the King ’ s circle of closest advisers ) in 1716 . Personal life . Hausmann was married to Karen Toller ; Hausmann ’ s father - in - law , Niels Toller , owned substantial property in Norway including a number of sawmills , and his mother - in - law was the daughter of the assessor and broker Anders Madsen in Tønsberg . Thus , as a result of marriage , Hausmann gained control of substantial property . Via his wife , he inherited the Old Bishop ' s Palace ( or Oslo Ladegaard ) in the Old Town of Oslo . Here he lived until his death . As the holder of Oslo Ladegaard he also had control over most of the land in the Old Town . Another acquisition through the marriage was of the Frogner Manor , which after his death went to his daughter Karen , who married to Frederik Christopher de Cicignon . Hausmann also established the iron works Eidsfos Verk in 1697 . During the expansionary period for Norwegian shipping from 1690 through 1710 Haussmann established himself among the leading ship owners in Christiania . In 1704 and 1705 , he was the city ' s largest shipowner and the fourth largest lumber exporter . He owned the large Bingen log booms on the Glomma river in Sørum and controlled much of the timber supply to Christiania . He exported his own lumber on his own ships and imported salt , wine and liquor . It has been suggested that he also participated in the lucrative - but risky - trade in contraband goods during the war . His only son , Frederik Ferdinand Hausmann ( 1693 – 1757 ) , married Cathrine Helvig Werenskiold . The union was childless and the Hausmann line died with Frederik .
