I have heard that pirate ships would use a fellow national flag until they got close to their prey and then raise the Jolly Roger.
This was known as "showing their true colors."
Hmmmm
Actually, flying the colors of another nation was common practice among naval vessels (as well as merchant vessels trying to avoid becoming a "prize") during times of war in the 17th and 18th centuries. This type of subterfuge was used when a captan spotted and wished to engage another vessel that was believed to be an enemy nation's or, if a merchant vessel, an ally of an enemy nation. The captain would choose the colors that he thought would give him the best chance to attack with the element of surprise, or pass unmolested if he was a merchant or was not up to an engagement and couldn't outrun the vessel in question. The true colors were run up just before engaging in battle. This type of misinformation increased the importance of the signal code books. If another ship flying the same colors couldn't respond to signal flags properly, they were pretty well known to be an enemy.
This aspect of the naval warfare of bygone days is brilliantly depicted in the "Aubrey, Martin" novels by the prolific Irish historical novelist Patrick O'Brian. O'Brian is considered the absolute best historical novelist to write about the ships and the seas of that perion. The movie starring Russel Crow was based on this series of novels, and if my memory serves correctly, there climax of the movie takes place when he disguises his (British) ship as an American whaler. I guess I'll just have to watch it again to be sure.

It was all about making the enemy think you were someone who you weren't and getting close enough to do him in.
The Patrick O'Brian novels are really good reading, but be warned, if you start reading them you will risk missing out on a bunch of DOD's. And if you are a shark, you may just end up being downgraded to a flounder.
BTW sorry if I'm drifting too far from the topic, but I'd love to hear the opinions of the forumites regarding the blades (or anything else) in that movie. If you haven't seen it you missed a great show. :thumbup: :thumbup:
