Karl Dönitz

Born on September 16, 1891, in Grünau, near Berlin, Karl Dönitz entered the Imperial German Navy in 1910. His early career was defined by the rapid technological changes in naval warfare. During World War I, he served on the light cruiser SMS Breslau in the Mediterranean.

In 1916, he transitioned to the submarine service, a decision that would define his future. As commander of the UB-68, he operated in the Mediterranean until his boat was forced to surface due to technical failures in 1918. Captured by the British, he spent time as a prisoner of war in the Redmires camp near Sheffield.

This experience provided him with a deep understanding of the vulnerabilities and strengths of submarine warfare, which he would later refine during the interwar period. Upon returning to Germany in 1920, he continued his service in the Weimar Republic's navy, commanding torpedo boats and eventually the cruiser Emden, which was used for training cadets.

During the 1930s, Dönitz became a vocal advocate for the expansion of the submarine fleet. He was instrumental in reviving the 'Rudeltaktik,' or wolfpack tactic, which aimed to overcome the limitations of individual submarine operations. By grouping U-boats, he sought to overwhelm Allied convoy escorts.

He was highly critical of larger submarines, arguing that the torpedo was the primary weapon and that smaller, more numerous vessels like the Type VII were more effective. His strategy relied on the use of radio communication to coordinate attacks, a method he believed would render defensive technologies like ASDIC (early sonar) less effective. Despite his strategic foresight, the German rearmament program prioritized land and air forces, leaving the navy with limited resources.

By the outbreak of World War II in 1939, Dönitz had only 57 U-boats, with fewer than 30 capable of reaching the Atlantic. He famously remarked upon the start of the war, 'My God! So it's war with England again!'

As the Commander of the Submarines (BdU), Dönitz oversaw the Battle of the Atlantic. The early years of the war saw significant successes, but the campaign was plagued by technical issues, most notably with the G7e torpedo, which often failed to detonate. Dönitz was forced to order the removal of magnetic pistols in favor of contact fuses to improve reliability.

As the war progressed, the loss of U-boats increased dramatically. By the end of the conflict, 648 U-boats had been lost, with 429 of those resulting in no survivors. The human cost was immense, with approximately 30,000 of the 40,000 men who served in the U-boat arm perishing.

Despite these losses, Dönitz remained committed to the war effort, even after the initiative shifted to the Allies in May 1943. He continued to deploy his remaining forces to relieve pressure on other branches of the German military until the final days of the war.

On April 30, 1945, following the suicide of Adolf Hitler, Dönitz was named his successor as head of state. This transition occurred during the final collapse of the German government. He formed what became known as the Flensburg Government, attempting to manage the final surrender.

On May 7, 1945, he ordered Alfred Jodl to sign the German Instrument of Surrender in Reims, France, which effectively ended the war in Europe. Dönitz continued to serve as the President of Germany and Supreme Commander of the Armed Forces until his cabinet was dissolved by the Allied powers on May 23, 1945. His brief tenure as leader was marked by the logistical and political chaos of a nation in defeat, and his primary objective during those final weeks was to oversee the orderly cessation of hostilities.

Following the war, Dönitz was indicted at the Nuremberg trials on three counts: conspiracy to commit crimes against peace, war crimes, and crimes against humanity; planning, initiating, and waging wars of aggression; and crimes against the laws of war. While he was acquitted of crimes against humanity, the tribunal found him guilty of crimes against peace and crimes against the laws of war. He was sentenced to ten years in prison.

After serving his sentence, he lived in a village near Hamburg, where he remained until his death on December 24, 1980. His life was marked by personal tragedy, including the loss of both his sons, Peter and Klaus, during the war. His legacy remains a subject of historical study, particularly regarding the effectiveness of his submarine strategies and his role in the final days of the Nazi era.

He remained a dedicated supporter of Hitler throughout his life, a fact he openly admitted.
