Theodor Detmers

Theodor Detmers (22 August 1902 – 4 November 1976) was the commanding officer of the German auxiliary cruiser Kormoran. He was also a recipient of the Knight's Cross of the Iron Cross which was awarded to recognise extreme battlefield bravery or successful military leadership.

Career
Detmers joined the German Navy in 1921 and served on the battleship SMS Hannover and SMS Elsass. He was educated on the Segelschiff Niobe and also served on the SMS Berlin. Detmers became a sublieutenant on the Emden. From 1926–28, he served on the Albatross. In 1927, he was promoted to lieutenant. From 1930–32, he served as staff officer and was then stationed on the cruiser Köln, on which he visited Australia in 1933.

In 1934, he served on torpedo boats and destroyers of the German Navy. In October 1938, he was in command of the destroyer Hermann Schoemann and participated in Operation Weserübung in April to June 1940.

HSK Kormoran
In July 1940, Detmers became captain of the commerce raider Kormoran, and captured or destroyed 11 enemy merchant ships. On 19 November 1941 Kormoran was intercepted by HMAS Sydney (1934). Detmers tried to pose as a Dutch merchant ship. He allegedly lacked the necessary naval codes, however, and was finally forced to engage Sydney. He sank the Australian cruiser in battle off Western Australia. His own ship was severely damaged and had to be scuttled, after which Detmers was captured and became a prisoner of war (POW). Detmers and the battle between Sydney and Kormoran was mentioned in the Wehrmachtbericht on Wednesday, 3 December 1941.

In December 1941, Detmers was awarded the Knight's Cross of the Iron Cross and in 1943, was promoted to the rank of Kapitän zur See. He had earlier received the first class Iron Cross.

Prisoner of war
From 1941 to January 1947, Detmers was held as a POW at HM Prison Dhurringile. While a prisoner, he wrote a coded account of the battle between HMAS Sydney and German auxiliary cruiser Kormoran that survived the war. Detmers tried to escape Australian captivity with other members of his crew, through a tunnel and then hoped to capture a sailboat to get to Indonesia; however, the attempt was unsuccessful. Later during his imprisonment, he suffered a stroke.

Post-captivity
Detmers returned to Germany in 1947 and was released from British captivity in Munster. Due to his stroke, he was incapacitated for service in the post-war German navy. In the early 1950s he married Ursula Reinhardt, daughter of an evangelical pastor. They had no children and he  died in Rahlstedt, Hamburg in 1976. Detmers wrote a book about his Kormoran experiences, which has been translated into English.
