"'raiding harbours'' is just not a very fair thing"
We're sure in agreement there.

Throw in my magazine guide and it's even less fair. I sank a battleship and two heavy cruisers just this morning in Yokosuka Harbor with just three torps. Then I created a little more carnage on the way up to Tokyo Harbor where I had a photo recon assignment. Then it took about an HOUR to get back out to open sea, what with destroyers, convoys and gun boats all over the place. So, while the harbors, themselves, are usually cupcakes, just getting out of there can be its own little challenge.
But, such is the peril of war.
