Lothar Witzke

Born in Kreis Koschmin, in the Province of Posen, Witzke was educated at Posen Academy and then entered the German Naval Academy as a seventeen-year-old cadet. By the beginning of the First World War he was a lieutenant[3] in the Imperial German Navy on the light cruiser SMS Dresden. After many months of excitement, during which the Dresden played havoc with Allied shipping and hid from British warships, she was eventually caught and sunk. Witzke's leg was broken in the action. Together with other survivors of the crew, he was interned in Valparaíso, Chile.

Early in 1916 Witzke escaped; and under an assumed name he succeeded in reaching San Francisco in May 1916 as a merchant seaman on board the SS Calusa. In California he reported to Franz Bopp, the German Consul General, who put him in touch with another saboteur, Kurt Jahnke, based in Mexico City. At this time the American law enforcement knew nothing of Jahnke's and Witzke's surreptitious activities. Both showed special aptitude for secret service work and were of a caliber far superior to Bopp's other agents. So cleverly did they cover their tracks that they were never even suspected during the period of US neutrality.

In addition to their work on the West Coast, Witzke and Jahnke made frequent trips east on sabotage missions. After Bopp was arrested, they gradually shifted their operations to the industrial Eastern seaboard. Double agents of the U.S. Military Intelligence Corps connected Witzke to the munitions explosion of July 1917 at the Mare Island Naval Shipyard in Vallejo, California.[4] Later, Witzke himself implied that he had taken part in the massive Black Tom explosion in New York harbor on July 30, 1916,[5] which killed at least four and as many as seven people and was heard as far away as Philadelphia. Later investigations would rule out his connection to both.[6][7]

Witzke was arrested at the Mexican border at 10 a.m. on February 1, 1918, near Nogales, Arizona. He claimed to be a Russian-American, "Pablo Waberski", returning to San Francisco. A 424-letter cryptogram was found sewn into the left upper sleeve of his jacket. Several months later this cryptogram was broken by John Matthews Manly,[8] who worked with Herbert Yardley[9] at the fledgling MI-8 and identified the bearer to the "Imperial Consular Authorities of the Republic of Mexico".[10] Witzke was convicted by a military court at Fort Sam Houston and sentenced to death. Twice he attempted to escape and once got out, but he was caught the same day emerging from a Mexican shack. On his return, a razor blade was found in his cell, and since suicide was feared, his top clothes were removed. On November 2, 1918, his sentence was approved by the Department Commander. However, with the Armistice of 11 November 1918 putting an effective end to the war, the death sentence was not carried out.

On May 27, 1920, President Woodrow Wilson commuted Witzke's death sentence to life imprisonment,[11] and he was transferred to Leavenworth Prison. Meanwhile, the Weimar Republic was exerting great pressure for his release. On April 30, 1923, the German Ambassador asked for Witzke's release on the grounds that other countries, including Germany, had released all POWs, including spies. At the same time, a prison report showed that Witzke had heroically prevented a disaster by entering a prison boiler room after an explosion. On that basis, Witzke was pardoned by President Calvin Coolidge, released on September 26, 1923, and deported to Berlin.

On his arrival in the Weimar Republic, Lieutenant Witzke was decorated by the Reichswehr with the Iron Cross, First and Second Class. He later joined the Abwehr. After the Second World War, Witzke lived in Hamburg.[12] He was a monarchist and a represented the German Party in the Hamburg Parliament from 1949 to 1952.[13]
