Operation Hannibal

Operation Hannibal was a German military operation involving the evacuation by sea of German troops and civilians from Courland, East Prussia, and the Polish Corridor from mid-January to May, 1945 as the Red Army advanced during the East Prussian and East Pomeranian Offensives and subsidiary operations.

The Soviet East Prussian Offensive by 3rd Belorussian Front under Army General Ivan Chernyakhovsky commenced on January 13, 1945 and, with Marshal of the Soviet Union Rokossovsky's 2nd Belorussian Front, subsequently cut off Prussia between January 23 and February 10, 1945. German Grand Admiral Karl Dönitz ordered General Admiral Oskar Kummetz, as Naval High Commander, Baltic, and Rear Admiral Konrad Engelhardt, head of the Kriegmarine's shipping department, to plan and execute the Rettungsaktion (evacuation operation).^[1] Donitz radioed a message to Gdynia in occupied Poland on January 23, 1945, to begin evacuations to ports outside of the Soviet area of operations. The operation was codenamed "Hannibal". Dönitz stated in his post-war memoirs that his aim had been to evacuate as many people as possible away from the Soviets.^[2]

Right up until his suicide, Adolf Hitler insisted that the war go on. The flood of military personnel and refugees eventually turned the operation into one of the largest emergency evacuations by sea in history (over a period of 15 weeks, somewhere between 494 and 1,080 merchant vessels of all types, including fishing boats and other craft^[3], and utilizing Germany's largest remaining naval units, would transport between 800,000 - 900,000 refugees and 350,000 soldiers^[4] across the Baltic Sea to Germany and German-occupied Denmark. This was more than three times the number of people evacuated at Dunkirk.

Operations

Refugees crossing the Baltic Sea

Operations commenced on January 23, 1945, running the gauntlet of British aerial-laid mines and Soviet aircraft, small naval units, and submarines operating in the Baltic. In the process of the evacuation, German navy ships bombarded Russian armor and infantry columns, firing more shells during the operation than they had in the previous five years of war and inflicting thousands of casualties on the pursuing Russians.

On January 30, the Wilhelm Gustloff, Hansa, and the whaling boat Walter Rau left the harbor at Gdynia in occupied Poland, bound for Kiel. The Hansa was forced to return to port with mechanical trouble, but the Gustloff, with more than 10,000 people aboard, continued. She was torpedoed and sunk by the Soviet submarine S-13 off the Pomeranian coast, with possibly as many as 9,400 fatalities, making this the worst maritime disaster in history. The East and West-Prussian refugees on the Walter Rau eventually made it to Eckernfoerde.

On February 9, the Steuben sailed from Pillau with between 3,000 and 4,000 mostly military personnel on board, heading for Swinemünde. She was also sunk by S-13, just after midnight; only 300 survived.

In early March, a task force composed of the heavy cruiser Admiral Scheer accompanied by three destroyers and the T-36 torpedo boat were giving cover to a German bridgehead near Wollin. During that operation, naval small craft managed to evacuate over 75,000 soldiers and civilians who had been isolated in that area. They were taken to larger warships and other transports lying offshore. While a number of these transports were sunk, large liners such as the Deutschland managed to break through and carry up to 11,000 people each.

During the night of April 4-5, a flotilla of small boats and landing craft evacuated over 30,000 soldiers and civilians from the Oxhöfter Kämpe and took them to Hela. It is estimated that nearly 265,000 people were evacuated from Gdańsk (German: Danzig) to Hela during the month of April alone.^[5]

On April 15, another large convoy consisting of four liners and other transports left Hela with over 20,000 soldiers and civilians. On April 16, the Goya was torpedoed and sunk by L-3, with the loss of over 6,000 lives; 183 survived.

Refugees arriving at a western harbor, already occupied by British troops

Initially, on his becoming President of Germany on May 1, Donitz was determined to continue the war, going so far as to instruct Colonel General Carl Hilpert that combat troops would have priority in evacuation to Germany from the Courland Pocket. It wasn't until the afternoon of May 6, with British troops practically on his doorstep, that he saw the writing on the wall.^[6]

From May 1 to May 8, over 150,000 people were evacuated from the beaches of Hela. At 21:00 on May 8, 1945, the last day of the war, a convoy consisting of 92 large and small vessels left the Latvian city of Liepāja (German: Libau) with 18,000 soldiers and civilians.^[7] While several hundred of those who had boarded small ships on the last day of the war or after were captured by Soviet MTBs, evacuations to the West continued for at least a week after all such movements were prohibited by the terms of the German surrender.

Losses

In addition to the Goya, Gustloff, and Steuben, 158 other merchant vessels were lost during the 15-week course of Operation Hannibal (January 23-May 8, 1945).^[8]
