You can see the bismark fighting the hood if you have IUB installed.
You gotta be in grid AD52 early morning on May 24th 1941, the exact place to be is 58km from the grids western edge and 36km up from the southern edge, here you will pick up war ship screws at about 5 AM.
You can just watch or try and intervene - the best part is there are no destroyers present though out the whole battle!
So, you can nail a revenge BB (Hood) and her cruiser escort making for some nice tonnage! if you have and engine upgrade you might be able to follow the bismark and her escort further and possibly bag more capitals that attack the bismark, i think another BB and an illustrious fleet carrier join in the hunt also, it just might be possible to get 10k in warship tonnage alone if you play your cards right, though it wouldnt be very historically accurate
