Karl Lennart Oesch (8 August 1892 – 28 March 1978) was one of Finland's leading generals during World War II. He held a string of high staff assignments and front commands, and at the end of the Continuation War commanded three Finnish army corps on the Karelian Isthmus. He received numerous awards, including the Finnish Mannerheim Cross during his service. Following the end of the Continuation War, he was tried and convicted for war crimes relating to the treatment of Soviet prisoners-of-war.

Early life

[edit]

Karl Lennart Oesch was born on 8 August 1892 in Pyhäjärvi to Christian Oesch and Anna Barbara Stegman. His parents were of Swiss origin and had moved to Finland before his birth. He attended school in Sortavala and studied in the Department of Mathematics and Physics at the University of Helsinki from 1911 to 1915.[1]

Jaeger Movement and Civil War

[edit]

Oesch joined the Finnish Jäger Movement, traveling to Germany in 1915. As a member of the Royal Prussian 27th Jäger Battalion, he fought on the German side of World War I on the Eastern Front, participating in combat in the region of Misa. He briefly returned to Finland to recruit more volunteers, before returning to Germany. In 1917, he was promoted Oberzugführer (English: Senior platoon leader).[1]

He returned to Finland in February 1918 with the main forces of the Finnish Jägers to take part in the Finnish Civil War on the side of the Finnish Whites. During the civil war, Oesch commanded the 8th Jaeger Battalion in the regions of Raasuli and Rautu.[1]

Oesch's battalion saw action especially in the area of the Rautu railway station, which was held by the Finnish Reds who were supported by an armored train. The reds withdrew from the station following multiple White attacks which captured the armored train but failed to capture the station area. Oesch reported that the withdrawal resulted in significant casualties, with 1200 Reds killed and 600–800 captured. The 8th Jaeger Battalion lost 199 men with 160 wounded while the total White losses were 670 men.[2]

1918 also saw Oesch commissioned as a captain in the Finnish Army, followed by a promotion to major. He briefly acted as the chief of staff of the Mountain Brigade (Finnish: Vuoristoprikaati) before taking the position of the chief of intelligence in the Finnish General Headquarters. Later that year, he took command of the Guards Jaeger Battalion (Finnish: Kaartin jääkäripataljoona), a position he would hold until 1920.[1]

Interwar years

Oesch married Anna Aitanga Niskanen in 1919. The couple had two children: son Karl Christian (born 1921) and daughter Ann-Mari (born 1922).[1]

In the 1920s and 1930s Oesch advanced rapidly in the Finnish Defence Forces. He briefly acted as an aide to the chief-of-staff of the Army High Command, before being given command of the Vyborg Regiment (Finnish: Viipurin Rykmentti). While holding that command, he was promoted lieutenant colonel in 1921.[1]

From 1924 to 1926, Oesch studied in the French military academy. During this time, he was also promoted colonel. Once he had returned to Finland, Oesch commanded the newly created general staff academy Sotakorkeakoulu. He briefly held command of the 1st Division from 1929 to 1930, after which he was promoted to major general and appointed Chief of the General Staff. During the following years, he oversaw significant reforms in the Finnish armed forces, which, according to Mikko Uola, "made possible the successes of the Finnish army in the Winter War". Oesch also served briefly as Deputy Minister of the Interior Affairs from 3 to 14 March 1932, during the crisis caused by the Mäntsälä rebellion. He was promoted to lieutenant general in 1936.[1]

Winter War and the Interim Peace

[edit]
Main articles: Winter War and Interim Peace

When the Soviet invasion of Finland started the Winter War on 30 November 1939, Oesch continued as Chief of the General Staff at Finnish Supreme headquarters under the Finnish Commander-in-Chief, Marshal Carl Gustaf Emil Mannerheim.[1]

In early March 1940, just prior to the end of the Winter War, Oesch was given command of the Coast Group, whose sector along the Bay of Viipuri had become critical. Oesch replaced Major General Kurt Martti Wallenius, who had taken command only three days prior.[1] According to Robert Edwards, Wallenius had "retreated to his command post and became very drunk" after losing his nerve from the intensity of the combat.[3] The Battle of Vyborg Bay saw both sides suffer significant losses, but by the evening of March 5 the Soviet 173rd Motor Rifle Division had established a bridgehead over the bay.[4] Further Soviet forces arrived at the bridgehead by 10 March, but the signing of the Moscow Peace Treaty on 12 March saw the hostilities end at 11 a.m. on 13 March.[5]

Following the end of the war, Oesch first returned to his previous post as the Chief of the General Staff for a few weeks, before taking the command of II Corps.[1]

Continuation War

Following Finno-German negotiations that had been ongoing from at least May 1941, the Finns mobilized on 10 June 1941 in preparation for the Continuation War, the Finnish component of the German invasion of the Soviet Union.[6][7] As part of these preparations, Oesch's II Corps was renamed IV Corps.[8] Consisting of the 4th, 8th, 10th and 12th divisions,[9] it was initially tasked with the defense of the southernmost sector of the Finno-Soviet border on the shore of the Gulf of Finland.[10]

Following the Soviet 23rd Army's withdrawal from Vyborg,[11] parts of IV Corps followed in pursuit.[12] A Finnish amphibious landing to Lokhaniemi, south of Vyborg,[13] together with a by-land envelopment conducted by the 4th and 12th divisions,[14] resulted in the pocketing of the Soviet 43rd, 115th and 123rd divisions following the Battle of Porlampi.[14] While most of the 115th and 123rd divisions eventually escaped the encirclement,[15] the operation resulted in the capture of some 3000 prisoners of war, including the commander of the Soviet 43rd Division, Major General Kirpichnikov, and large amounts of materiel.[15][16]

In 1942, Oesch was given command of Olonets Group in the Olonets Isthmus between Lakes Onega and Ladoga.[1] While the front had stabilized into trench warfare,[17] Oesch's forces soon came under attack by six soviet divisions and four brigades.[18] The attack was eventually repulsed, but caused significant casualties for both sides.[18]

The trench warfare period ended on 9 June 1944 with the Soviet Vyborg–Petrozavodsk Offensive, which soon broke the Finnish lines.[19] On the morning of 14 June 1944, Oesch received a call from Lieutenant General Aksel Airo with the following message:[20]

Everything's going to hell on the Isthmus. Get yourself there on orders from the commander-in-chief, the corps are yours.

Oesch was given the title Commander of the Isthmus Forces,[21] with the forces under his command soon including the III, IV and V Corps.[22] The Soviet offensive pushed the Finnish forces first to the VT-line, and eventually to the VKT-line, where the situation eventually stabilized around 17 July, following the fall of Vyborg and the battles of Tali-Ihantala and Vyborg Bay.[23] Oesch was awarded the Mannerheim Cross on 26 June 1944.[24]

Following the stabilization of the situation, Soviet forces from the Finnish front were redirected to other fronts, and on 27 July the Soviets indicated they would be open to a negotiated peace that allowed for an independent Finland. The Finnish parliament accepted the Soviet demands on 2 September. As agreed during the negotiations, Finnish forces began to observe a cease-fire at 07:00 a.m. on 4 September. Soviet forces followed suite some 25 hours later, at 08:00 a.m. on 5 September.[25]

After the end of the war, Oesch briefly commanded the General Staff of the Finnish General Headquarters before taking command of an army corps later that year.[1]

Trial for war crimes

[edit]

Oech was arrested for war crimes in 1945. In 1946, he was sentenced to 12 years in prison on involuntary manslaughter charges for having encouraged the killings of 17 Soviet prisoners of war. The sentence was later reduced to three years by the Supreme Court of Finland.[26][27]

The trial and sentence stemmed from events in November 1941, when Oesch had given an order to shoot political commissars and other prisoners-of-war who refused to work or follow orders. Any paperwork related to such executions would not be properly filled, listing the executed as "removed" (Finnish: poistettu)[28][29] In addition, in the fall of 1944, Oesch had ordered the destruction of documents relating to shot prisoners-of-war.[30]

Later life

[edit]

After Oesch was released from prison in 1948, he devoted himself to military history, researching and writing extensively on Finnish experiences in World War II. He founded the Kansa Taisteli magazine and wrote a book on the 1944 events on the Karelian Isthmus. According to Mikko Uola, Oesch was embittered by what he perceived as a lack of recognition for his actions.[1]

Oesch died in Helsinki on 28 March 1978[1] and is buried in the Hietaniemi cemetery.[31]

Awards

[edit]

During his life, Oesch received several notable military awards. The most notable of these are the Finnish Mannerheim Cross and the Grand Cross of the Order of the Cross of Liberty. In addition, he received the Finnish Order of the White Rose of Finland; the Latvian Order of the Three Stars; the Norvegian Order of St. Olav; the Polish Order of Polonia Restituta and Golden Cross of Merit; the French Legion of Honour; the Swedish Order of the Sword and Order of the Polar Star; several German and Prussian Iron Crosses; the Danish Order of the Dannebrog; and the Estonian Order of the Cross of the Eagle.[1]

In 1960, he was given an honorary doctorate by the University of Turku.[32]
