Born on 23 June 1915 at St Petersburg, Russia, to a Polish family. While still a school student he obtained glider and powered aircraft pilot licences. In 1935 he joined the Polish Air Force Cadet Officers' School, from which he graduated as the 3rd best. Until August 1939 he was an instructor and commanded the training platoon of the 3rd Air Regiment's Training Flight. At the end of August he was posted to the 131st Fighter Flight, and with the unit he fought in the Polish campaign of 1939. He was credited with 3.5 confirmed kills. Wounded on 6 September in a combat with a He 111 raid he was sent to a hospital, remaining there until March 1940. As he was likely to be arrested by the Germans, he had to escape from the hospital while still not fit. He joined the Home Army (Polish underground resistance movement) and was active in the Aviation Intelligence Department of the Home Army HQ. Among others, he was the take off officer responsible for departure of RAF Dakotas that landed in occupied Poland to pick up essential people and cargo ('Wildhorn' operations). He was particularly distinguished in the operation 'Wildhorn III' when the Dakota loaded with V2 rocket missile components and technical documentation captured by the Polish Home Army bogged down in the ad hoc landing field. After three unsuccessful take off attempts the British pilot wanted to try no more and set the aircraft on fire, as he was aware that there was a troop of some 200 Luftwaffe soldiers and two AA guns within a mile of the field. Gedymin proposed to break down a wooden shed and put the planks under wheels. This time the aircraft successfully took off and delivered its invaluable cargo to RAF Campo Cassale in Italy.Following WWII Capt. Gedymin has worked for many years in the LOT Polish Airlines.
His decorations include
the Silver Cross of Virtuti Militari
and Cross of Valour and two Bars.
