I'll try to take a screenshot tomorrow if the mission is still available. About the black ships, I got a Tirpitz B from a Black Friday Container and I have the Tirpitz mission to play 10 battles each for 250 doubloons (2500 doubloons total). The mission in question was a surprise to me because I haven't done anything. It's not from a code, bundle, purchase nor anything like that. I thought this mission was something from Christmas or New Year for all players but I haven't seens anyone else get it.
