In his will, he had stipulated that his wife should keep unaltered estate to pay the debt, and that the eldest son, John Christian, should inherit the entire duchy but remain unmarried for the time being.

The widowed Duchess Dorothea was in charge of the duchy during the ensuing war years, but was unable to pay off the debt, which, on the contrary, was still growing.

[2] After the inheritance agreement in 1633, August Philipp severed his ties with Denmark and emigrated to Germany at the age of 21, where he made a career as an officer.

[3] In 1646 he bought the estate Haus Beck neat the city of Ulenburg, Prince-Bishopric of Minden, from 1648 in the Duchy of Westphalia within the Margraviate of Brandenburg, from his sister Sophie Katharina, which she had received in dowry from her brother John Christian, upon her marriage to Anthony Günther, Count of Oldenburg.

His sons and their descendance went into Prussian, Polish and Russian service until his grandson's great-grandson took over Glücksburg Castle and the line changed its name to Schleswig-Holstein-Sonderburg-Glücksburg in 1825.
