The Psilander affair was an incident that occurred in Skálafjørður near Tórshavn in the Faroe Islands on 20 June 1940 in World War II. The British Royal Navy captured the four Swedish destroyers HSwMS Psilander, Puke, Romulus and Remus, together with the Swedish Lloyd passenger ship Patricia and the Trelleborgs Ångfartygs tanker Castor, despite the fact that Sweden was neutral. The Swedish Navy had chartered Patricia to take the crews for the destroyers from Sweden to Italy, and accompanied them on their return voyage. After the crew did work to adopt them, they left La Spezia on 14 April.
