A cold November wind whips around us. We stand before a simple plaque. It’s a tribute to a man you might not know. A man who changed the course of World War II for Poland. This is the sierż inż Seweryn Wielanier ps. Sapieżyński Plaque.
This unassuming memorial on Londyńska Street marks the home of Seweryn Wielanier. He was an extraordinary engineer. More than that he was a key figure in the Warsaw Uprising. He’s remembered for his ingenious design. It was a submachine gun called the Błyskawica.
Seweryn wasn’t just any engineer. Before the war he studied at the prestigious Wawelberg and Rotwand Engineering School. He worked at the Pocisk ammunition plant. He honed his skills in designing and manufacturing crucial parts for ammunition. His expertise was essential for Poland’s defense efforts.
Then came the Nazi occupation. Seweryn joined the Armia Krajowa. Under the pseudonyms Sapieżyński Witold and PR he worked in secret. He was pivotal in the clandestine production of Błyskawica submachine guns.
Imagine the risk involved. Working in clandestine workshops across occupied Warsaw. Producing weapons under the very noses of the enemy. It was a dangerous job but vital for the resistance. The Błyskawica was unique. It was designed for easy assembly in small workshops. This was crucial given the scarcity of resources and the high risk of discovery.
Seweryn’s design borrowed elements from the British Sten Mk II and the German MP 40. However the Błyskawica was distinctively Polish. It had a simple yet robust design. The lightness and collapsible stock made it easy to conceal under a coat. The fact that it didn’t require welding made mass production possible.
Over 700 of these guns were produced during the war. They played a key role in the Warsaw Uprising. The sheer number produced is a testament to the skill and dedication of Seweryn Wielanier. His contribution to the fight for freedom remains significant.
After the Uprising Seweryn left Warsaw with the civilian population. He later returned. He lived here on Londyńska Street until his death in 1993. This plaque a small but significant tribute. It stands as a reminder of his ingenuity. It is a symbol of resistance and Polish resilience during World War II. It is a testament to one man’s extraordinary contribution to his country. So take a moment to reflect on the legacy of sierż inż Seweryn Wielanier ps. Sapieżyński. A true hero of the Warsaw Uprising.
