Was just about to comment. What a boat load of answers! Hadn't heard of TRIREME before, so have learned something new today.
Googled Armada, just out of interest & it said:
The Spanish Armada brought with it 22 galleons & 108 armed merchant vessels. They fought an English Force of 34 warships & 163 armed merchant vessels. Now we know! Thanks everyone for help & humerous comments.
