Katrina Lanze, née von Menen, was born in 1915 and is two years younger than her brother Carl. Although recently married, she still lives at the family home in Mecklenburg because her husband Jürgen is often away on duty.
Jürgen Lanze is a Lieutenant Commander in the German navy. Like Manfred von Lieber, his remit is U-boats, and he is often needed at Lübeck.
When we first meet Jürgen, Carl congratulates him on his Knight’s Cross, but he downplays the attention. He is highly skilled but modest and is far more concerned about the safety of his crew than earning medals.
