In November 1939, he was arrested by the NKWD (Soviet Secret Police) for attempting to escape to Hungary to join the newly forming Polish Army. He was imprisoned in Nadwrna and Stanislaww and then spent nine months in prison in Odessa. In September 1940, he was sentenced without trial to three years in the Russian Gulag. First he worked in the stone quarries in the Samara Labour Camp, and then in May, 1941 he was sent to the Northern USSR to the Peczora Gulag.
Amnesty and release from prison were granted to the Polish soldiers as a result of the Sikorski - Majski Treaty in September, 1941. After difficult travels through the southern part of the USSR, he reached Buzuluk and joined the army of General Anders.

He was decorated with the Cross of Valour, as well as many other medals. At the end of the war he received the rank of lieutenant.
After the war he studied at the University of London, but left in 1947 to settle in Canada, where he continued his studies and was subsequently employed by Ontario Hydro. In retirement, he was an active member of the Polish church, choir and social groups in Toronto, and a member of the Society of "Siberians" in Krakw.
