Ok....thanks for all the advice....decided to wait till dark and headed in.....spent most of the evening jostling and getting into posistion whilst fire off here and there. Mopped three up with the deckgun. Took some damage and lost a good man but think it was worth it in the end.
Back to base, all fuelled and rearmed and its only the 26th Jan...off to find the rest of the Java fleet
Note...In "rea" life would they have just continued to mill around as they did here, whilst all around ships were sinking....wouldnt they have made a run for it. They were just there for the taking ??
