After his secondary school time in Schleiz he decided to become an officer in the police force and was taken over by the army in Worms with a patent from April 1, 1934.

In 1940 he married Gabriele Döber, at that time living in Katowice/Upper Silesia (today Poland), who, according to his official missing persons report on August 1, 1944, is said to have emigrated to the USA at the end of the Second World War.

During this time he took part in the campaigns to Poland (September 1939), France (May to June 1940) and the Battle of Britain (July to November 1940).

Major Blechschmidt and his group flew missions in the Great Don Arc from an airfield surrounded by the enemy, probably Tazinskaya.

[5] Although Soviet tanks advanced to the edge of the airfield, the destroyer group under his command flew rolling missions against tanks, artillery and infantry positions of the Soviets despite the lowest cloud height, snowdrift and lowest visibility conditions and despite the artillery and mortar fire lying on the airfield.

On 13 July 1943 he was shot down by Noël Castelain[8] in air combat with Soviet and Allied fighters east of Orel near Ulyanovo-Bolchov.
