Redox - Corrosion

Anyways, can anyone help me with this question..

In 1763, the British Admirality covered wooden ship HMS Alarm with copper sheeting to protect it from marine worms. This was sucessful but, they reported: '... we were surprised to perceive the effect of the copper had upon iron where the two metals touched... the nails and staples... were found dissolved into a rusty paste.' Briefly explain this occurrence and how it might have been prevented.

This should be easy for you guys...

I know that both the metals undergo wet corrosion, but I don't know anything about the effect on having the two metals in contact.
