In May 1945, German submarines sat in Japanese ports from Singapore to Kobe, their crews half a world from home. When Germany's war ended, their Japanese ally had its own plans for them, and it had written those plans down a week before.

This is what happened to U-181, U-862, U-195, U-219 and the two former Italian boats at Kobe: the admiral's dinner at Seletar, the flags that came down, the jungle internment camp, and the German sailors kept back to teach Japanese crews how to run their boats.

Topics covered: the Monsun U-boats in the Far East, Admiral Wenneker's code word, Vice Admiral Fukudome at Seletar, the seizure of the U-boats as I-501 to I-506, UIT-24 and UIT-25 (Comandante Cappellini and Luigi Torelli) under three flags, Japan's April 1945 plan for Germany's surrender, Batu Pahat and Changi, and the scuttling of the boats in 1946.
