Man, these two teams REALLY do not like each other.
Apparently, this feud between the Royal Navy and the Marine Nationale goes back to the late 18th century, when they faced off in the siege of Toulon during the French Revolutionary Wars. Little history lesson for you.
The rugby match itself between the two teams goes back to 2005 and the series is currently tied at 6-6, with the Marine Nationale winning this most recent match, 28-6.
Maybe for the tie-breaking match they should take it out to the seas and duke it out old school naval battle style. Now THAT would make for one crazy video.
