Lauri Törni was born on May 28, 1919, in the town of Viipuri, then part of independent Finland and today the Russian city of Vyborg. His father, Hjalmar Törni, was a ship captain, while his mother, Rosa Maria (Kosonen), managed the household. He had two younger sisters, Salmi and Kaija.
The family was stable and respected, and Törni grew up in an environment that valued physical achievement. He attended a commercial school and excelled in sports, especially skiing and boxing. As a young man, he was a childhood friend of Sten Suvio, who later won a gold medal in boxing at the 1936 Berlin Olympics.
Törni served in the anti-communist paramilitary Civil Guard, and in 1938 he entered military service, joining the 4th Jaeger Battalion stationed in the village of Kiviniemi on the Karelian Isthmus.
World War II began on September 1, 1939, when Nazi Germany invaded Poland. Three months later, when the Soviet Union attacked Finland and the Winter War began on November 30, 1939, Törni's enlistment was extended and his unit was moved to the front.
He held the rank of corporal and was responsible for supply logistics, a position that did not satisfy his energy or ambition. One night, with temperatures dropping to 42 degrees below zero Celsius, he slipped out of his camp unnoticed by his guards, walked alone to a Soviet position, captured a soldier, and brought him back to the Finnish lines.
Recognizing his potential, his commanders assigned him to light infantry duties, and his unit took part in fighting around Lake Ladoga, including the encirclement and destruction of Soviet divisions at Lemetti, a battle that demonstrated the Finnish forces' ability to annihilate a numerically superior opponent.
As the Winter War ended with the Moscow Peace Treaty in March 1940 and Finland ceded territory including the Karelian Isthmus, Törni had been sent for officer training and was appointed a second lieutenant in the reserve forces.
The peace lasted a little more than a year. In June 1941, following Germany's invasion of the Soviet Union, Finland entered the war again in what became known in Finland as the Continuation War, or the second Soviet-Finnish war, fighting alongside Nazi Germany with the stated aim of recovering the territory lost in 1940.
Before the new conflict began, Törni had gone to Vienna, Austria, for seven weeks of training with the Waffen-SS, the military wing of the Nazi paramilitary organization. He returned to Finland in July 1941 holding the rank of Untersturmführer in the special forces, equivalent to a second lieutenant in the U.S. Army, in addition to his Finnish rank.
This training was part of a broader arrangement under which about 1,400 Finnish volunteers joined the Waffen-SS. Marshal Carl Gustaf Emil Mannerheim, commander of the Finnish forces, later requested their return to serve in the Finnish army.
In the Continuation War, Törni's reputation grew far beyond what he had achieved during the Winter War. He returned to active service in the Finnish armed forces and was seriously wounded in 1942 when he skied over a landmine that detonated. He was not stopped by this, and in 1943 the Finnish high command established a dedicated unit under his command, an infantry detachment that carried his name unofficially and operated deep behind Soviet lines.
Törni's detachment was a light infantry force trained for reconnaissance, sabotage, and combat in the forested terrain of Karelia, a border region between Finland and the Soviet Union. The detachment became feared by Soviet commanders and celebrated in Finnish military culture.
One of the men who served under Törni during that period was a young reconnaissance soldier named Mauno Koivisto, who later became president of Finland from 1982 to 1994. The unit's effectiveness reached such a level that the Soviet army put a bounty of 3 million Finnish marks on Törni's head.
The last battle fought by Törni's unit was the Battle of Ilomantsi in July and August 1944, the last significant battle between Finland and the Soviet Union in the Continuation War, fought in the forests of northern Karelia. Finnish forces, operating in difficult terrain against a much larger Soviet army, succeeded in encircling and repelling two Soviet divisions.
Earlier, specifically on July 9, 1944, Törni was awarded the Mannerheim Cross, Second Class, Finland's highest military decoration. Of the nearly 600,000 Finns who served in the Continuation War, only 191 received this honor.
The Moscow Armistice in September 1944 ended the Continuation War. Its terms required Finland to expel German forces from its territory, leading to the start of the Lapland War, a conflict between former allies that lasted until 1945. This time, the Finns were fighting against Nazi Germany.
The armistice also required Finland to demobilize most of its military forces. Törni was discharged in November 1944, suddenly finding himself unemployed and unwilling to accept an outcome that left the Soviets in control of his family's homeland.
In January 1945, a Finnish resistance network loyal to Germany recruited him, and he left for Germany for training in possible sabotage operations in the event of a Soviet occupation of Finland. When that training stopped in March 1945, and with no way to return to Finland, Törni joined a Waffen-SS unit fighting Soviet forces near the city of Schwerin in northern Germany.
He surrendered to British forces in the final days of the war, and in June 1945 he escaped from a British prisoner-of-war camp in Lübeck in northern Germany and made his way back to Finland.
What awaited him at home was not the reception he deserved. Finland, operating under the constraints of the Moscow Armistice and Soviet pressure, had no room to protect men who had continued fighting in German ranks after the armistice.
When Törni arrived in Helsinki, Finland's capital, he was arrested by the Finnish state police, Valpo. Törni escaped, was arrested again in April 1946, and was tried for treason for continuing to serve in the German army during the Lapland War. In January 1947, he was sentenced to six years in prison.
He served part of the sentence in a regional prison in the city of Turku in southwestern Finland, and escaped again in June 1947. He was recaptured and transferred to the Riihimäki state prison in southern Finland. He remained there until December 1948, when President Juho Paasikivi granted him a pardon.
After his release, unable to find a stable future in Finland, Törni left in 1949 with his wartime executive officer, Holger Pitkänen. They crossed the border from the Finnish city of Tornio to the Swedish city of Haparanda and traveled to Stockholm, Sweden's capital, where Törni stayed with an aristocratic Swedish family that had sheltered a number of Finnish officers after the war.
In Stockholm, he met a Swedish-Finnish woman named Marja Kops and became engaged to her. To find work, he joined as a sailor under an assumed name aboard the merchant ship SS Bolivia, bound for Caracas, Venezuela.
From Caracas, he made his way to a Swedish cargo ship, MS Skagen, heading to the United States. In the Gulf of Mexico, he jumped from the ship and swam ashore. He arrived in the United States as an undocumented immigrant and a stateless man.
Törni traveled to New York City, where the Finnish-American community helped him. In 1954, he enlisted in the U.S. Army under the name Larry Thorne.
He was immediately drawn to the U.S. Army Special Forces, and between 1958 and 1962 he served with the 10th Special Forces Group in Bad Tölz, West Germany. During this period, he was second-in-command of a search and rescue operation in the Zagros Mountains of Iran, a mission in difficult mountain terrain that strengthened his reputation among Special Forces officers as a man who solved problems no one else could.
In November 1963, Thorne was deployed to South Vietnam, where he operated near the Cambodian border. His unit ran camps for irregular civil defense groups, training and leading local fighters against communist Viet Cong forces. During this time, he was wounded and received the Purple Heart and the Bronze Star for valor.
By then he had fought communists for a quarter of a century under the flags of three very different countries.
On October 18, 1965, Törni boarded a South Vietnamese Air Force CH-34 helicopter as part of Operation Shining Brass, the first secret mission tasked with identifying Viet Cong supply points along the Ho Chi Minh Trail in Laos and directing airstrikes against them.
Two helicopters launched from the camp and met a U.S. Air Force forward air control aircraft amid deteriorating weather over a mountainous area in Phuoc Son district in central Vietnam's Quang Nam province. As one helicopter flew through a gap in the clouds to insert the six-man team, Törni's helicopter and the small observation aircraft remained near the location. When the first helicopter returned above the clouds, both aircraft had disappeared. Search teams found nothing, and the crash site was never located.
Shortly after his disappearance in the helicopter crash, Thorne was posthumously promoted to major and awarded the Legion of Merit and the Distinguished Flying Cross. He remained listed as missing in action for 34 years.
In 1999, a joint Finnish-American team recovered the remains of those aboard the crashed helicopter. In 2003, after his identity was officially confirmed through dental records, Lauri Törni, known as Larry Thorne, was buried with full military honors at Arlington National Cemetery in Virginia. He remains the only former member of the Waffen-SS buried at Arlington.
He was 46 years old when his helicopter crashed in South Vietnam.
