Major John Sehmer whose home unit was the Royal Tank Regiment had already completed an SOE mission in Serbia when he volunteered for a second mission to Hungary accompanied by Private Willis and Wilson as part of Operation Windproof in Slovakia and Hungary to encourage and support a Slovak uprising by partisans; establish communications with London and assist the Hungarian Government to negotiate an armistice with the allies.
Sehmer and his team worked at the maximum range of the RAF Special Duties Halifax bombers based in Bari Italy, which meant they had a limited time over drop zones before having to return to base. Frequent bad weather also made navigation difficult and supply drops were sometimes cancelled. Added to the problems with air operations were political arguments between the Foreign Office in London, Moscow and several governments in exile.
Shortly after Sehmer and his men parachuted into Slovakia on 18 September 1944 he sent a report saying they had been dropped around fifteen miles from the drop zone and almost on top of German troops and ran the risk of being shot by Slovak sentries.
After arriving the ‘Sehmer Team’ joined forces with an American OSS team informally called ‘Dawes Mission’ located in the Hron Valley in the Lower Tatras where they stayed in a farmhouse in a village called Polomka in the Brenzo district located in the Banska region of Central Slovakia.
The date is unknown when the farmhouse was surrounded by 250 men, and some were locals led by the Germans. It was later said a partisan sentry had fallen asleep and axis forces were able to circle the farmhouse undetected before they came under heavy machine gun fire. The partisans with the support of SOE (Sehmer, Wilson and Wills) along with an unknown number of OSS agents held out for three-hours and after being bombarded by German artillery were forced to escape but all were captured.
Sehmer, Willis and Wilson were imprisoned at Banska Bystrica in central Slovakia and on 6 January 1945 were transported to Mauthausen concentration camp and interrogated the same day.
SS-Standartenfuhrer Franz Zieries
On 7 January Sehmer was badly beaten by SS-Standartenfuhrer Franz Zieries who was the Mauthausen camp commander. It is known Sehmer was suspended by his arms from the ceiling of the interrogation room and tortured for four days.
On or around 23 January 1945 Major Sehmer was shot through the head by camp commander Zieries. It is not known what happened to his body but was most likely thrown into a mass grave along with several American OSS operatives who had also been killed; among the victims was Lieutenant James Holt Green serving with OSS who had arrived by parachute a day before Sehmer and his men. In total, eleven Americans were also shot or beheaded by the Germans. On 24 January 1945 the German overseas news agency made the following radio announcement, ‘Eighteen members of the Anglo-American group of agents headed by an American named Green and an Englishman named Sehmer who posed as a major were caught on Slovakia soil in the hinterland of the German fighting sector. Investigations revealed they had the task to carry out acts of sabotage in Anglo-American interests. The agents who wore mufti when arrested were sentenced to death by court martial.
In January 2004 the commander of the unit that captured the SOE and OSS teams along with partisans was arrested at his home in Munich. The German authorities stated that eighty-six-year-old Ludislav Niznansky was being investigated for the murder of civilians; there was no mention of the men serving with SOE and OSS and Niznansky was acquitted when the case came to trial.
According to the Commonwealth War Graves Commission Major John Sehmer was awarded an MBE!
