Document 6: Agneta Horn: Agneta Horn was the daughter of Gustav Horn, Count of Björneborg and Kristina Oxenstierna, and the granddaughter of Axel Oxenstierna. She was born in Riga in what is now Latvia, because her father was a Swedish military officer stationed outside of the country at the time of her birth. At six weeks of age, despite the unusual nature of a whole family living together in a Swedish military camp, Agneta and her mother joined Gustav at a camp in Kurland, in western Lithuania. The family lived there together through the fall and winter. In the spring when Gustav traveled to Germany with the military, Agneta and her mother returned to their Swedish home. Soon after, Agneta's younger brother Axel was born. The family was reunited with Gustav again in Neumark after Axel's birth. Horn writes: "Because she took us both with her and sailed to Germany and landed at Wolgast, where my father met her. Then, he took her and us with him to the army, which at the time was in Neumark" ("Agneta Horn’s Leverne", 1910). Therefore, from a young age, Agneta was exposed to Swedish military campaigns, particularly the war between Sweden and Denmark. In her autobiography she recalls this experience: "But then came the King of Denmark and camped across from our army. And they began to shoot at each other's camps with guns. Because they were shooting so close together the bullets fell into our tent" ("Agneta Horn’s Leverne", 1910). In 1634 Gustav Horn was captured by Imperialist military forces and held as a prisoner of war for eight years. Kristina died when Agneta was a child. Her father remarried, and Agneta was raised for much of her childhood by Ebba Leijonhufvud, a "cold and heartless" aunt.
