There is an exhibition currently on at The National Maritime Museum in Greenwich: « Turner and the Sea », which you might be interested in if you are going to London soon.
Here’s the link: http://www.rmg.co.uk/whats-on/events/turner-and-the-sea
Tickets can be bought online.
Also at the National Maritime Museum is a free exhibition called: « Nelson, Navy, Nation »
If you can’t get to the museum, you might be interested to read a series of « tweets » from the Battle of Trafalgar 1805, which tell the story of the battle ‘live’.
Once you get your head around modern technolgy reporting historical events, it’s quite riveting .
