In February, the British destroyer HMS Cossack boarded the German transport ship Altmark while in Norwegian waters, thereby violating Norwegian neutrality, rescuing POWs also held in violation of Norwegian neutrality (the Altmark was obliged to release them as soon as she entered neutral territory).
Pada bulan Februari, kapal perusak Inggris HMS Cossack menumpang kapal angkut Jerman Altmark sementara di perairan Norwegia, dengan demikian melanggar kenetralan Norwegia, menyelamatkan tawanan perang yang juga melanggar kenetralan Norwegia (Altmark berkewajiban untuk melepaskan mereka begitu dia memasuki wilayah netral).
