Kazimierz Leski, known by his nom de guerre Bradl, utilized a stolen identity as a Wehrmacht Generalmajor to navigate German-occupied Europe over 25 times during the Second World War. A versatile operative, he combined engineering precision with clandestine intelligence work, later enduring years of imprisonment under Poland's communist regime before his eventual rehabilitation.
Engineering and Naval Design
Born in Warsaw in 1912, Leski pursued a technical career despite the political setbacks faced by his father, a pioneer in the Polish arms industry. After graduating in 1936, he joined the Nederlandse Verenigde Scheepsbouw Bureaus in The Hague. He contributed significantly to naval architecture, particularly through his studies at the Delft University of Technology. He served as the head designer for the Orzeł class submarines, specifically the ORP Orzeł and ORP Sęp, after patenting a new mounting system for ballast-tank funnels.

Following the 1939 German invasion, Leski served in the Polish Air Force until his plane was downed by Soviet forces. After escaping captivity, he joined the underground organization Muszkieterowie, which later merged into the Home Army. Despite lingering physical injuries, he excelled in intelligence gathering, compiling comprehensive data on German military units, supply logistics, and transport infrastructure. His clandestine network facilitated communication between occupied Poland and the Polish Government in Exile in the United Kingdom.
Espionage Under Cover
Leski conducted high-risk courier missions across Europe, often posing as General Julius von Halmann. This persona granted him access to critical military installations, including the Atlantic Wall construction sites and the field staff of Field Marshal Gerd von Rundstedt. Beyond intelligence, he directed efforts to aid individuals held within the Pawiak prison system. During the 1944 Warsaw Uprising, he commanded the Bradl company of the Miłosz battalion, earning multiple decorations, including the Silver Cross of the Virtuti Militari.
Post-War Imprisonment and Later Life
In the aftermath of the war, Leski worked to reconstruct the Gdańsk Shipyard under the alias Leon Juchniewicz. His cover was compromised in 1945, leading to his arrest by the communist secret police. He spent years on death row and in solitary confinement, enduring torture while facing fabricated charges of collaboration with German forces. Following his 1956 rehabilitation, he returned to engineering. He received the Righteous Among the Nations award in 1995 and remained a resident of Warsaw until his death in 2000.
