Thanks gentlemen; very much appreciated.

I had recently bought and watched the DVD "Convoy, War for the Atlantic", a serious lengthy documentary series produced in England. I'd reccommend it t anyobe both the archive film footage an the information.

Although not mentioned in this documentary, a little known fact is that Malaysia's Penang Island was home to a fleet of long range German submarines that preyed upon Allied shipping during WWII. They shared a Japanese submarine base. Apparently the submariners of both countries despsed each other, inly due to the Germans' arrogance and sense of racial superiority. A private outfit has cleared the overgrown jungle that has hidden most of the site and it is now open to visitore.
