Advice for harbour raids

[Wreford-Brown]

What harbours have you raided, when did you raid them and what advice can you offer to fellow Kaleuns who wish to follow in your footsteps?

If you enjoy harbour raiding then please give others the benefit of your hard won experience. What route did you take, what ships were anchored, what ships defended the harbour?

I've raided Gibraltar in April 1941. It is possible to get almost to the Rock of Gibraltar under the layer (160m or deeper) then creep into the harbour area. HMS Nelson (33k tons) and a small depot ship (6500 tons) were on the north western side and three Southampton/London class (10-13k tons each) were on the north eastern side along with a couple of static destroyers. In the harbour itself there's another Southampton class plus a troop transporter, modern tanker, large and medium cargo and a few other smaller ships. Watch out for torpedo nets on the northern side of the harbour - I took a lot of damage when I hit one net and broke the surface for a few seconds as those capital ships have a shedload of firepower (but can't traverse very quickly). Torpedo nets in general seem to finish about 2 submarine widths from the harbour walls in any port, so I sneak in by running very close to harbour walls.
The only things protecting Gib are the static surface ship's guns and 2 or 3 ASW trawlers and Isles class, all of which seem to be either blind and deaf or just plain stupid in early 1941.
