very good to know, but like you say, should be more japanese ships, but is not my case in the first mission i sunk over 100.000tons between luzon and formosa, and other convoy near manila in 29 december 1941, but in the second mission seems disappears everything, in luzon strait too, stuck 3 weeks and nothing.....so....after this, and after all that stuff you said
any suggestion about what i do?
