battleships would sometimes sail with the convoy, inside the convoy, outside the convoy, and zig zagging ahead and behind.
you have to remember that convoy lanes were much wider in real life than in SH3.
you also have to remember that the Kriegsmarine frequently sent heavy surface units like pocket battleships, commerce raiders and bomber groups into the open sea to engage the convoys... u-boats were not the only threat. These battleships and cruisers were deployed as a means of having some heavy guns around to protect from such threats.
this is the best as it can be simulated within the constraints of SH3
