Later, Maniots won another victory when the Royal Navy of the United Kingdom defeated the Regia Marina of Italy in the Battle of Cape Matapan (March 27-March 29, 1941) on Cape Tenaro. However, Nazi Germany attacked Greece in order to support the Italians. The Greeks were forced to retreat, and soon Mani revived its forgotten role as a center for refugees. During April 1941, the British started evacuating their troops from Porto Kagio. By the end of that month, Mani and the rest of Greece were under Italian and German occupation.
