​​​ He began his pilot training in 1922 and quickly rose to the rank of Captain. In 1927, he achieved the title of Major Chief Pilot and became the head of several pilot training schools.

By 1939, already a Colonel, he was involved in mapping the advance of the German armed forces in the regions of Gdańsk and East Prussia. After escaping the German occupation, he reached the United Kingdom, where he was placed in charge of the Polish Air Camp in Eastchurch on 18 December 1939. On 1 July 1940, he was appointed Commander of RAF Bramcote and later RAF Swinderby.

​​Having passed the age of forty and being a high-ranking officer, he was forbidden by the military command to fly due to his valuable operational skills. However, on 4 July 1941, Stachoń chose to disobey this order when one of the missions lacked sufficient crew.

He had trained on Wellington aircraft and now served in No. 301 (Pomeranian) Squadron, RAF, a Polish heavy bomber squadron. Out of a strong sense of duty, he decided to join the operation, which ultimately resulted in his death when his aircraft was shot down by German fighters near Absen, Netherlands. The rest of his crew survived and were taken prisoner.

After Stachoń’s death, because he had disobeyed military orders, he was posthumously stripped of his Major General rank. As a result, his wife was denied a military pension, and he was buried among lower-ranking soldiers at the Maczek Memorial. Years later, after considerable effort, his son succeeded in having his father’s rank officially reinstated.
