Józef Pszenny

In 1939 during the September campaign, holding the rank of lieutenant, he commanded the 2nd company of sappers of the 7 Sapper Battalion.[2] During the German occupation of Poland, he was the creator of the underground sabotage group Batalion Saperów Praskich (eng. Praga Sapper Battalion),[3] which was established in 1940, bearing the colloquial name of "Chwacki Battalions". Later, he was the commander of the disposable patrol squad separated in the middle of 1942 from the Sapper's Battalion, and at the same time commanded the line battalion of this branch constituting its staff and technical facilities. At the end of July 1943, "Chwacki" was dismissed to work in the command of the Sapper Department of "XII-s" District Warsaw AK, and his position was taken by Ludwik Witkowski "Kosa".[4]

After the war he was in exile in the United States, where he was active in veteran organizations.
