Just picked up a really nice postcard postmark 1935, Gdnyia, of Polish submarine ORP Ryś.
During the pre-war months of 1939, Polish school children were encouraged to save their pocket money to help purchase submarines. ORP Ryś was a Polish mine-laying submarine belonging to the Wilk class. Ryś means “Lynx” in English. The escape of the battle-damaged submarine from the German Navy to neutral Swedish waters during the September 1939 campaign captured the imagination of schoolboys throughout Poland. ORP Ryś was interned in Sweden Sept 18 1939 until war's end.
