If you're feeling really brave, the HMS Nelson is at anchor in Gibraltar, along with 2 Southampton Class in early October 1940 (can't remember the exact date, but within the first 2 weeks of Oct). I remember cos me and the rest of my crew died a slow death on the bottom as flooding consumed us after a pesky Elco spotted us during an early hours surface infiltration. Those guns from the Nelson certainly caused a few holes that no amount of fingers could plug....
It's over on the far eastern side of the bay. (GWX).
