Joint Operations in The Indian Ocean

The idea of stationing U-boats in Malaya and the East Indies for operations in the Indian Ocean was first proposed by the Japanese in December 1942. As no supplies were available at either location, the idea was turned down, although a number of U-boats operated around the Cape of Good Hope at the time. A few days after Cappellini reached the East Indies, U-511 became the first U-boat to complete the voyage. This boat carried the Japanese naval attache Admiral Naokuni Nomura from Berlin to Kure. The boat was given to Japan as RO-500; its German crew returned to Penang to provide replacement personnel for the main submarine base being established at a former British seaplane station on the west coast of the Malayan Peninsula. A second base was established at Kobe; small repair bases were located at Singapore, Jakarta and Surabaya. As part of the dispersal of U-boat operations following heavy losses in the North Atlantic during the spring of 1943, Wilhelm Dommes was ordered to sail his U-178 from his operating area off South Africa to assume command at Penang.
